▼ We will look at the dynamics of tra c
congestion that is formed without any
specifc origin. This type of event can be viewed in metropolitan areas daily as
highway traffic jams. We assume that these tra c congestions are formed from small disturbances in the flow of traffic. This will be modelled using a dynamical system where each differential equation represents a vehicle's behaviour. We will utilize Matlab's built-in numerical integration function ode45 which uses Runge-Kutta integration methods. Through our simulations, we are able to determine that with the addition of small perturbations to an equation in the steady-state flow solution, we will induce traffic
congestion.

A transport protocol for best-effort content-based

▼ Content-based publish/subscribe (or simply
content-based) networking is a relatively new communication
paradigm compared to IP networking, with a different approach to
addressing network hosts. In content- based networking addressing
as well as information dissemination center around information and
interests. A host's address is represented by its interest and
information is routed by a network of brokers to hosts with
relevant interests. We advocate the idea that content-based
networking should be implemented and offered as a basic network
service and be accessible everywhere and to all applications.
Best-effort content-based systems which substantiate this idea are
high-throughput low-delay publish/subscribe systems in which
messages are treated as datagrams without end-to-end or in-network
acknowledgments and flow control. In such systems, publishers
(senders) do not avoid or even detect
congestion, and brokers
respond to
congestion by simply dropping overflowing messages.
These systems are therefore unable to provide reliable message
delivery and fair resource allocation and to properly handle
traffic anomalies, which may degrade the overall quality of
service. Furthermore, extensive usage of concurrent matching and
routing algorithms in broker software causes frequent message
reordering in the brokers and ultimately out- of-order delivery of
messages to clients. These shortcomings of best- effort
content-based systems impede their deployment for many applications
and environments. For instance, the lack of
congestion control
hinders the deployment of such systems in the open Internet, where
congestion-unaware flows are considered a major threat to the
stability of the network. With this motivation, we propose an
end-to-end ``transport protocol'' that improves three key
properties of best-effort content-based systems namely, message
ordering, reliability, and
congestion control. These essential
requirements have been previously addressed at the protocol and
broker-level, at the cost of much higher complexity and lower
messaging efficiency. On the contrary, our guiding principle in
designing this transport protocol is to view the underlying
best-effort publish/subscribe network as a black box and only
assume that it provides a general publish/subscribe API. This
design principle has multiple advantages. First, the transport
protocol works with virtually every best-effort content-based
system, for it makes no assumptions about the underlying network.
Second, individual clients can optionally take advantage of this
transport protocol for better quality of service while those with
relaxed requirements can opt out and avoid unnecessary overheads.
More importantly, the end-to-end protocol has a minimum impact on
the favorable performance and inherent simplicity of the
best-effort network since it does not require the involvement of
the broker network. Our methodology in developing this transport
protocol, on the one hand, is based on understanding the body of
related research on end-to-end solutions for FIFO…

▼ Historically, congestion pricing is considered as an
efficient pricing mechanism to decrease total social cost by
eliminating rush hour congestion. However, in order to eliminate
rush hour congestion, deterministic settings are usually necessary.
In recent research, even if some uncertain sources are introduced,
congestion price under uncertainty is still not clear addressed. In
this thesis, I brief the literature of congestion pricing for
deterministic cases, discuss the traditional sources of uncertainty
in literature, and introduce the possible source of uncertainty for
congestion pricing. Base on those congestion pricing uncertainties,
I analytically show how the road congestion and total social cost
will be influenced. Also, congestion option is introduced as a
market-based treatment to deal with uncertainty to reduce the total
social cost. Furthermore, this thesis analytically shows that the
congestion option can be used to reduce total social cost by
altering commuters’ departure behavior and reducing commuters’
risk. At last, numerical formulations are given to justify the
robustness of our results respect to more general congestion
uncertainty.

▼ Dérégulation du marché de l'électricité a affiché de nombreux changements dans l'économie et a influencé les chercheurs à initier des études dans ce domaine. Italie fournit une étude de cas intéressante pour explorer le marché de l'électricité en raison de ses spécifications. Notre projet se compose de trois études quantitatives indépendant pour voir le marché de l'électricité Italien en trois angles différents. La première étude permet de répondre la question de la prévision causée par la volatilité du marché de l'électricité. Le résultat suggère une méthode de prévision alternative pour la modélisation de prix de l'électricité sur l'Italie. La deuxième recherche examine l'impact des énergies renouvelables sur l'apparition de la congestion et ses coûts. Nous analysons les propriétés quantitatives de l'estimation économétrique afin de comprendre le mécanisme économique et d'en tirer la suggestion de la politique. Enfin, la recherche finale analyse l'interdépendance des prix dans six macro-zones du marché italien de l'électricité.
Deregulation of electricity market has displayed many changes in the economy and has influenced researchers to initiate studies in this field. The issue of the deregulated arises as the volatility of the wholesale price increases because of the new mechanism in price determination. Italy provides an interesting case study for exploring the electricity market because of its specifications. Our project consists of three independent quantitative research to view the Italian electricity market in three different angles. The first study is aimed to address the forecasting issue caused by the volatility of electricity market. The result suggests alternative forecasting method for modelling electricity price on Italy and comparisons between univariate and panel framework. The second research examines the impact of renewable energy on the congestion occurrence and cost. We analyse quantitative properties of the econometric estimation in order to gain insight into the economic mechanism and to draw policy suggestion. Finally, the final research attempts to address the interdependence of prices in six macro-zones of the Italian electricity market.

▼ This thesis proposes a new problem of identifying large and tangled logic structures in a
synthesized netlist. Large groups of cells that are highly interconnected to each other can
often create potential routing hotspots that require special placement constraints. They can
also indicate problematic clumps of logic that either require resynthesis to reduce wiring
demand or specialized datapath placement. At a glance, this formulation appears similar
to conventional circuit clustering, but there are two important distinctions. First, we are
interested in finding large groups of cells that represent entire logic structures like adders
and decoders, as opposed to clusters with only a handful of cells. Second, we seek to pull
out only the structures of interest, instead of assigning every cell to a cluster to reduce
problem complexity. This work proposes new metrics for detecting structures based on
Rent?s rule that, unlike traditional cluster metrics, are able to fairly differentiate between
large and small groups of cells. Next, we demonstrate how these metrics can be applied to
identify structures in a netlist. Finally, our experiments demonstrate the ability to predict
and alleviate routing hotspots on a real industry design using our metrics and method.

▼ Transmission Control Protocol (TCP) is the dominant transport protocol today and likely to be adopted in future high‐speed and optical networks. A number of literature works have been done to modify or tune the Additive Increase Multiplicative Decrease (AIMD) principle in TCP to enhance the network performance. In this work, to efficiently take advantage of the available high bandwidth from the high‐speed and optical infrastructures, we propose a Stratified TCP (STCP) employing parallel virtual transmission layers in high‐speed networks. In this technique, the AIMD principle of TCP is modified to make more aggressive and efficient probing of the available link bandwidth, which in turn increases the performance. Simulation results show that STCP offers a considerable improvement in performance when compared with other TCP variants such as the conventional TCP protocol and Layered TCP (LTCP).

▼ La problématique de la congestion automobile à Bruxelles pousse divers acteurs (politiques, organismes de gestion, lobbys, citoyens) à se mobiliser pour favoriser ou s’opposer à une modification de la politique de mobilité en vigueur, ce qui peut donner lieu à une lutte de pouvoir. Si modifier la fiscalité de la mobilité n’est pas jugé crédible en raison de l’étroitesse du territoire à Bruxelles et de la faible élasticité de la demande des automobilistes aux taxes, l’instauration d’un péage urbain apparaît comme crédible, c’est-à-dire réalisable et efficace. Mais la prudence reste de mise car personne n’est capable de prédire, à l’heure actuelle, l’impact qu’aurait l’instauration d’un péage urbain à Bruxelles en termes économique, sociétal et environnemental. L’acceptabilité du péage urbain par la population nécessite la mise en œuvre préalable d’autres alternatives, plus modestes, pour réduire la congestion comme la nécessité d’une meilleure communication aux usagers, le télétravail, le covoiturage, l’efficacité du réseau de transports publics et un plan de stationnement à l’échelon régional. Chacune de ces solutions est plus ou moins crédible à son échelle, mais l’utilité, l’intérêt et l’efficacité des mesures seront perçues de manière différente et chacun adaptera ou non à sa façon sa manière de se déplacer dans la ville. Ces cinq mesures peuvent permettre, si pas de solutionner, du moins de réduire, en partie, la congestion automobile à Bruxelles et ainsi de favoriser une mobilité plus durable, générant moins d’externalités négatives.

▼ A cluster-based router is a new router architecture
that is composed of a cluster of commodity processing nodes
interconnected by a high-speed and low-latency network. It inherits
packet processing extensibility from the software router, and
forwarding performance scalability from clustering. In this thesis,
we describe a prototype cluster-based router, including the design
of the cluster-based router architecture and the addressing of
critical issues such as the design of a highly efficient
communication layer, reduction of operating system overheads,
buffer recycling and packet packing. By experimental evaluation, we
expose its forwarding capacity scalability and latency variance. We
also evaluate and analyze the potential hardware bottlenecks of its
commodity processing nodes, and present the correlation between the
reception and transmission capabilities of an individual port as
well as ports on the same bus. We propose an adaptive scheduling
mechanism based on system state information to manage the adverse
effect of this correlation on the router performance. We also
investigate internal congestion in the cluster-based router. To
manage the internal congestion, we propose two backward explicit
congestion notification schemes: a novel queue scheduling method
and an optimal utility-based scheme. We show the effectiveness of
these schemes either by ns-3 simulation, experimental evaluation,
or both. We also analyze the stability of the optimal utility-based
BECN internal congestion control scheme through theoretical proof,
simulation and experimental evaluation.

▼ In this thesis, the problems of pricing are investigated on networks with heterogeneous users. I seek the possibility and conditions through an anonymous toll scheme to achieve a simultaneously improvement of multi-criteria system performance. First, I look into the possibility and conditions of a Pareto-improving and Revenue-neutral congestion pricing scheme on a simple bi-mode network: this scheme aims at improving system performance, making every individual user better off (includes increasing social welfare) and having zero total revenue simultaneously. Second, comparing with the “do-nothing” case, I look into the possibility of Pareto-improving of system performances measured in both time and monetary units (the system time and the system cost) through a congestion pricing scheme in general networks. In the first part, since Pareto-improving and Revenue-neutral scheme suggested here charges transit users negative tolls and automobile users positive tolls, it can be a proper way to implement congestion pricing and transit subsidy in one step; also it will possibly improve system performance, increase social welfare and offset the inequity for the poor. I concern with two problems. First, whether or not Pareto-improving and Revenue-neutral pricing scheme exists for certain targeted modal split flow pattern? Second, what are the different Pareto-improving situations when a bi-mode transportation system serves for travel groups with different VOT distributions respectively? For a general VOT distribution, the condition that everyone will be better off is found. Furthermore, the impacts of details of different travel communities’ VOT distributions on the better off situations after Revenue-neutral toll are studied and the better off situations can be classified into three cases. Then I focused on travel groups with uniform VOT distributions. A continuous range in terms of the targeted highway flow always exists to realize everyone better off through Revenue-neutral pricing. The larger the VOT range is, the smaller the range is. A common range that the system time is decreased is exactly the range that Pareto-improving and Revenue-neutral pricing scheme exists, independent of VOT distribution. However, considering the increasing and decreasing property of the loss of the most adverse user among the community, a large VOT range does not always mean the adverse inequitable situation after Revenue-neutral pricing. When the reduction of travel time on highway through pricing is large enough, the large widening rich-poor gap will give more benefit to the most adverse user. In the second part, comparing with the untolled user equilibrium situation, the necessary condition of Pareto-improving of the total system travel cost and the total system travel time through a road pricing scheme in general networks is found. I give a classification of the untolled user equilibrium situations which are collectively exhaustive and mutually exclusive. Two among the classification are identified as extreme situations where the two…

▼ In this study we investigate the vulnerability of road
networks to interdictions. We consider that an intentional attacker
wants to maximize the congestion level on the network by
interdicting some links of the network. The behavior of the drivers
traveling on the network is assumed to follow user equilibrium
traffic assignment which is affected by the interdiction initiated
by the attacker. In this problem, we propose a method, to reduce
the damage to lowest level. An attack-to-protect (ATP for short)
method is developed to solve for optimal interdiction strategies
and to explore the effectiveness of protecting the identified
vulnerable links of the network. Numerical experiments are
conducted to examine factors that influence the effectiveness of
this method. Specifically, we compare the efficiency of this method
when applied on different Cartesian grids. Managerial insights into
the vulnerability and protection of road networks are drawn from
the analysis.

▼ The original use of the Internet was to share expensive resources by addressing endpoints using IP addresses. These days the Internet is mostly used to access distributed content rather than to share resources, but we still end up addressing endpoints in order to access distributed content. Named Data Networking (NDN) is an approach where content names are addressable, rather than endpoints. NDN's main approach is moving the internet towards a content distribution architecture and provides better support to mobile devices compared to TCP/IP. One of the design concerns of NDN is congestion control, which is the topic of this paper. Many recent studies on congestion control in NDN suggest either using an end-to-end approach or a hop-by-hop approach. Our NDN Congestion Control Protocol (CCP) is designed to detect and control congestion at the consumer end without the use of RTT measurements or congestion signaling. CCP is a receiver driven, window based protocol that can detect and control congestion by making use of measurements of delay along the forwarding path. We implement CCP using ndnSim simulator and compare it to an end-to-end AIMDD (additive increase/multiplicative decrease) scheme that behaves the same way as TCP.

▼ The Internet is constantly changing and evolving. In this thesis the behaviour of various aspects of the implementation of TCP underlying the Internet are measured. These include measures of Initial
Congestion Window (ICW), type of reaction to loss, Selective Acknowledgment (SACK) support, Explicit
Congestion Notification (ECN) support. We develop a new method to measure
congestion window reduction due to three duplicate ACK inferred loss. In a previous study 94% of classified servers showed window halving, whereas we found that 50% of classified servers exhibited Binary Increase
Congestion control (BIC) or Cubic style behaviour, which is a departure from a Request For Comments (RFC) requirement to reduce the
congestion window by at least 50%. ECN is predicted to improve Internet performance, but previous studies have revealed a low support for it 0.5%, and ECN connections failed at a high rate due to middlebox interference 9%; in this thesis we show a steady increase over time of ECN being implemented and supported 7.2%-10.3%. ECN testing of webservers with globally routable IPv6 adderesses showed a higher success rate 21.9%. Analysis of
congestion control behaviour such as Tahoe, Reno and New Reno showed New Reno dominating more strongly than before, increasing from 35% to 70% of popular webservers. SACK sending analysis revealed that 45% of popular webservers implement it properly, as compared to 18% in earlier studies. SACK receiving analysis showed higher results to the earlier studies, with success increasing from 64.7% to 81.1%. For both of these SACK studies results for webservers with globally routable IPv6 addresses showed a higher success rate when errors remained low. Analysis of ICW indicates that 75% of popular webservers implement the older ICW regime of an initial
congestion window of two or less packets, as compared to 96% in previous studies. The new regime of an ICW of three or four packets depending on segment size was implemented at 20%. We see from these results that RFCs do affect TCP implementation, but change can be slow. However we see that implementation and support for modern TCP features is increasing.

▼ In this dissertation, we propose that it is necessary
to consider wireless neighborhood as a single indivisible entity
for
congestion control in multi-hop wireless networks. We precisely
define this neighborhood for a class of contention-based wireless
networks and validate it with three protocols. We design IFRC, an
open-loop rate-based fully distributed
congestion control protocol
for multi-hop wireless sensor networks with tree-like traffic
pattern. We design WCP, a closed-loop AIMD-based fully distributed
end-to-end
congestion control protocol for multi-hop wireless
networks with arbitrary traffic pattern. In addition, we design
WCPCap, an explicit-rate feedback
congestion control protocol for
multi-hop wireless network. While they differ in their local
mechanisms to achieve
congestion control all these protocols
recognize neighborhood, as per our definition, as a single entity
and achieve near optimal performance in both simulations and real
deployments.

▼ The topic of this thesis is to study how weather is affecting regional bus traffic in Tampere region. Study focuses on evaluating the direct effects of air temperature and snowfall. Delays of regional bus traffic were evaluated by using real time location data and timetable schedule data from regional buses in Tampere region. Based on this information, link travel times were counted for each stop-to-stop trip on the route of the bus. This approach also enabled the evaluation of between which stops the biggest delays occur and during which time of the day. The weather conditions were evaluated by using open weather observation data from Finnish Meteorological Institute and different ranges of air temperature and precipitation were categorized. Link travel times during good driving conditions were used as a baseline when compared to link travel times observed during more challenging conditions. Effect of weather was also evaluated during different times of the day and week.
It is expected that there is a correlation between adverse weather and longer link travel times in bus traffic.
• Hypothesis 1a: Adverse weather causes longer link travel times for the bus traffic
• Hypothesis 1b: Effects of adverse weather to link travel times are more severe in specific stop-to-stop links
First objective is to evaluate Hypothesis 1a and to find out how clear and big the correlation between severe weather and changes in bus link travel times are. Objective of the study is also to try to find out which components of the weather are affecting the link travel times more (air temperature or precipitation).
If hypothesis 1a is proven to be true, the next object will be to try to examine if delays are affected by weather more in some specific places or areas of the region.

▼ Morning commuters congest central business district roadways as they search for
parking. A survey of studies suggests that on average 30% of downtown
congestion is
attributed to drivers searching for parking. This imposes great commuting costs. Drivers
may behave in a more socially-optimal manner if parking spots were priced in such a way
as to internalize the
congestion externality or if a driver were made more aware of the
parking
congestion prior to selecting a parking destination. If efficiency in parking were
improved through policy, there would be the added benefit from declines in fuel
consumption, and associated negative environmental effects, as well as less traveled
roadways, decreasing both accidents and annual maintenance.
Vickrey (1971) was first to propose a responsive price policy to address urban
traffic
congestion. Drivers could coordinate their actions to reduce
congestion and
maximize efficiency through full information and a responsive pricing mechanism. With
today's technology it may be possible to provide real time information to drivers at a
reasonable cost. This thesis uses a laboratory experiment to determine the extent to
which responsive pricing improves efficiency and coordination over a fixed parking price system. It also seeks to find whether the effect differs when drivers know the real-time
parking price. No clear consensus has emerged on the ability of responsive pricing to
improve parking efficiency or that providing agents with information about
congestion
and prices improves coordination or efficiency. This thesis explicitly examines the
differences of
subject and group welfare and the ability to coordinate between a
responsive price and a fixed price system with and without specific price information.
Welfare and coordination were measured by the
subject's earnings and their decisions of
where and when to park in the different market settings.
The experiment results show that the availability of pricing information and not
the type of pricing has a statistically significant impact on the level of coordination, yet
the reduction does not translate into an improvement in total welfare. No treatment
effects on total net commuter earnings were statistically different across treatments for
the total group of commuters or by group of the two commuter types, but statistical
significant differences did occur for gross earnings. The treatment effects on gross
earnings occurred only at the individual level and the improvement in gross earnings
depended on the type of commuter. The commuter that had a greater willingness to pay
to park in the central business district compared to the other type of commuter earned
significantly more gross earnings, on average, in the full information responsive price
treatment than the same type of commuter in the other treatments. The level of
coordination did not reach the optimal level for any of the treatments, but the full
information treatments did have a greater degree of coordination. These results suggest that…

▼ Dans cette thèse, nous proposons un mécanisme appelé Initial Spreading qui permet une optimisation remarquable des performances de TCP pour les connexions de petites tailles, représentant plus de 90% des connexions échangées dans l’Internet. Cette solution est d’autant plus intéressante que pour certaines technologies telles qu’un lien satellite, le temps d’aller-retour particulièrement long est très pénalisant, et des solutions spécifiques ont dû être implantées qui empêchent l’intégration du satellite dans un système de communication plus large. Nous montrons que l’Initial Spreading est non seulement plus performant, mais surtout plus général car pertinent dans toutes les situations. De plus, peu intrusif, il ne compromet aucune des évolutions de TCP passées ou à venir.
In this Ph.D. Thesis, we propose a mechanism called Initial Spreading that significantly improves the TCP short-lived connexions performance, and so more than 90% of the Internet connections. Indeed, if regular TCP without our mechanism can be considered as efficient for terrestrial networks, its behavior is strongly damaged by the long delay of a satellite communication. Satellite community developed then some satellite specific solutions that provide good performance, but prevent the joint use of satellite and other technologies. We show therefore that Initial Spreading is not only more efficient than regular solutions but enables also the use of an unique protocol whatever the context. Moreover, being non-intrusive, it is suitable for past and future TCP evolutions.

▼ Congestion threshold is embedded in the
congestion definition. Two basic
approaches exist in current practice for setting the
congestion threshold. One common
approach uses the ?free-flow? or unimpeded conditions as the
congestion threshold.
Another approach uses target or ?acceptable? conditions. The limited research that has
been conducted on the
congestion threshold issue focuses on operational problems or
policy debates, but relatively little investigation of the effect on decision-making for
transportation investment and resource allocation.
This research investigated the differences inherent in the threshold choices using
detailed freeway data from seven metropolitan areas.
Congestion performance measures
of delay per mile, Travel Time Index and Planning Time Index were evaluated. This
research specifically examined: 1) the ranking values of
congestion measure for different
congestion thresholds under a variety of real-world travel time distributions, 2) the
relationship between change of
congestion threshold and change of performance
measure, and 3) the appropriateness of using speed limit as a
congestion threshold
choice by evaluating the peak and off-peak average speed changes in relation to a speed
limit change in Houston, Texas.
The rankings of
congestion measures for freeway segments hold steady across
the
congestion thresholds ranging from 60 mph to 30 mph and across the
congestion
measures. From an investment point of view, the
congestion threshold speed used is not
a concern for funding allocation.
The relationship between the delay values for an alternative threshold and the 60
mph threshold has a quadratic form. As the alternative threshold decreases further away
from 60 mph, the increment is larger. The more congested a section is, the less the
threshold affects measured
congestion. For very congested sections, most of the delay is
associated with speeds below 30 mph.
The posted speed limit affects travel time distribution in the free flow driving
condition but does not affect travel time distribution during congested driving conditions.
However, if the speed limit or a percentage of speed limit is used to estimate the
congestion, the amount of
congestion may be underestimated because the free flow
speed is higher than the speed limit.

▼ The Internet has become the preferred transport medium for almost every type of communication, continuing to grow, both in terms of the number of users and delivered services. Efforts have been made to ensure that time sensitive applications receive sufficient resources and subsequently receive an acceptable Quality of Service (QoS). However, typical Internet users no longer use a single service at a given point in time, as they are instead engaged in a multimedia-rich experience, comprising of many different concurrent services. Given the scalability problems raised by the diversity of the users and traffic, in conjunction with their increasing expectations, the task of QoS provisioning can no longer be approached from the perspective of providing priority to specific traffic types over coexisting services; either through explicit resource reservation, or traffic classification using static policies, as is the case with the current approach to QoS provisioning, Differentiated Services (Diffserv). This current use of static resource allocation and traffic shaping methods reveals a distinct lack of synergy between current QoS practices and user activities, thus highlighting a need for a QoS solution reflecting the user services. The aim of this thesis is to investigate and propose a novel QoS architecture, which considers the activities of the user and manages resources from a user-centric perspective. The research begins with a comprehensive examination of existing QoS technologies and mechanisms, arguing that current QoS practises are too static in their configuration and typically give priority to specific individual services rather than considering the user experience. The analysis also reveals the potential threat that unresponsive application traffic presents to coexisting Internet services and QoS efforts, and introduces the requirement for a balance between application QoS and fairness. This thesis proposes a novel architecture, the Congestion Aware Packet Scheduler (CAPS), which manages and controls traffic at the point of service aggregation, in order to optimise the overall QoS of the user experience. The CAPS architecture, in contrast to traditional QoS alternatives, places no predetermined precedence on a specific traffic; instead, it adapts QoS policies to each individual’s Internet traffic profile and dynamically controls the ratio of user services to maintain an optimised QoS experience. The rationale behind this approach was to enable a QoS optimised experience to each Internet user and not just those using preferred services. Furthermore, unresponsive bandwidth intensive applications, such as Peer-to-Peer, are managed fairly while minimising their impact on coexisting services. The CAPS architecture has been validated through extensive simulations with the topologies used replicating the complexity and scale of real-network ISP infrastructures. The results show that for a number of different user-traffic profiles, the proposed approach achieves an improved aggregate QoS for each user when compared…

▼ In this dissertation we examine some of the challenges faced by the
congestion
control algorithms of TCP in emerging networks. We focus on three main issues.
First, we propose TCP with delayed
congestion response (TCP-DCR), for improving
performance in the presence of non-
congestion events. TCP-DCR delays the conges-
tion response for a short interval of time, allowing local recovery mechanisms to
handle the event, if possible. If at the end of the delay, the event persists, it is treated
as
congestion loss. We evaluate TCP-DCR through analysis and simulations. Results
show significant performance improvements in the presence of non-
congestion events
with marginal impact in their absence. TCP-DCR maintains fairness with standard
TCP variants that respond immediately.
Second, we propose Layered TCP (LTCP), which modifies a TCP flow to behave
as a collection of virtual flows (or layers), to improve eficiency in high-speed networks.
The number of layers is determined by dynamic network conditions. Convergence
properties and RTT-unfairness are maintained similar to that of TCP. We provide the
intuition and the design for the LTCP protocol and evaluation results based on both
simulations and Linux implementation. Results show that LTCP is about an order
of magnitude faster than TCP in utilizing high bandwidth links while maintaining
promising convergence properties.
Third, we study the feasibility of employing
congestion avoidance algorithms
in TCP. We show that end-host based
congestion prediction is more accurate than previously characterized. However, uncertainties in
congestion prediction may be un-
avoidable. To address these uncertainties, we propose an end-host based mechanism
called Probabilistic Early Response TCP (PERT). PERT emulates the probabilistic
response function of the router-based scheme RED/ECN in the
congestion response
function of the end-host. We show through extensive simulations that, similar to
router-based RED/ECN, PERT provides fair bandwidth sharing with low queuing
delays and negligible packet losses, without requiring the router support. It exhibits
better characteristics than TCP-Vegas, the illustrative end-host scheme. PERT can
also be used for emulating other router schemes. We illustrate this through prelim-
inary results for emulating the router-based mechanism REM/ECN.
Finally, we show the interactions and benefits of combining the different proposed
mechanisms.

▼ We investigate the issues in making a delay-based protocol adaptive to heterogeneous
environments. We assess and address the problems a delay-based protocol
faces when competing with a loss-based protocol such as TCP. We investigate if noise
and variability in delay measurements in environments such as cable and ADSL access
networks impact the delay-based protocol behavior significantly. We investigate these
issues in the context of incremental deployment of a new delay-based protocol, PERT.
We propose design modifications to PERT to compete with the TCP flavor SACK.
We show through simulations and real network experiments that, with the proposed
changes, PERT experiences lower drop rates than SACK and leads to lower overall
drop rates with different mixes of PERT and SACK protocols. Delay-based protocols,
being less aggressive, have problems in fully utilizing a highspeed link while operating
alone. We show that a single PERT flow can fully utilize a high-speed, high-delay link.
We performed several experiments with diverse parameters and simulated numerous
scenarios using ns-2. The results from simulations indicate that PERT can adapt
to heterogeneous networks and can operate well in an environment of heterogeneous
protocols and other miscellaneous scenarios like wireless networks (in the presence of channel errors). We also show that proposed changes retain the desirable properties
of PERT such as low loss rates and fairness when operating alone.
To see how the protocol performs with the real-world traffic, the protocol has
also been implemented in the Linux kernel and tested through experiments on live
networks, by measuring the throughput and losses between nodes in our lab at TAMU
and different machines at diverse location across the globe on the planet-lab.
The results from simulations indicate that PERT can compete with TCP in
diverse environments and provides benefits as it is incrementally deployed. Results
from real-network experiments strengthen this claim as PERT shows similar behavior
with the real-world traffic.

▼ Traffic
Congestion is an ever growing chronic problem in the transportation system soon after
the invention and mass production of automobiles. All major cities both in developed and
developing countries are facing the problem due to increasing travel demand which follows
economic and population growth. Traffic
congestion directly affects commuters with an
increased travel time, excessive delay in a queue, increased fuel cost, delay for important
appointment and job, loss in productive hours; and it indirectly affects the living standard and
the environment as well. Hence, traffic
congestion cause upon road users and cities to incur a
significant amount of money for both economic and social costs. Quantifying the level of the
traffic
congestion and understanding how much effect and cost are being incurred due to traffic
congestion; hence, will be important for making improvement decisions and evaluate
implemented mitigation measures.
Following the economic and population growth in Addis Ababa, traffic
congestion problem has
emerged and the problem is even growing faster. In this study, the level of the traffic
congestion
in Addis Ababa city was quantified using travel time approach. The city’s one of the most
congested East-West corridor was considered and travel time, traffic volume, and vehicle
occupancy data were collected at four midblock and four intersections. Accordingly, the travel
rate, the delay rate, total travel delay (Veh-Min and Per-min), buffer index and planning time
index were calculated. And also, the average hourly travel rate is correlated with the average
hourly traffic accident data and
congestion spots and accident black spots were plotted on the
GIS map to see the relationship between the traffic accident and traffic
congestion.
Accordingly, the result showed that on average about 18,000 Veh-min or 38 Veh-day and about
169,000 Per-min or 352-person-day are wasted at each major intersection entry and the city
incurs annually about 5-8 Million Birr per intersection only for vehicle and fuel cost. The result
also showed that the city’s traffic accident rate correlated with travel rate better than traffic
volume and the
congestion spots identified from questionnaire data conside with the black spots
identified by the national road safety agency.

▼ Congestion has long been a concern to
transportation operation and planning. Various methods and
technologies have been developed and applied in detecting
congestion. This study focuses on using bus as probes to indicate
recurrent
congestion on urban roadway networks.
In this study, bus speeds are used to reflect indications
of
congestion. Bus speed data collected over “homogeneous days” are
pooled in order to find indications of recurrent
congestion. Bus
speeds collected during a time period at each location are compared
to bus speeds collected during other time periods (or during the
whole day) at the same location. For practical purposes, the entire
bus route investigated for the purpose of method development,
validation, and demonstration is discretized into 10 meter spatial
sections, and time of day is discretized into 30 minute time
intervals. Each 10 meter long spatial section and 30 minute
duration time interval constitutes a space-time cell for which
existence or absence of an indication of
congestion is
determined. Three different methods are used to
determine the existence or absence of an indication of
congestion
for each space-time cell. Two of the three methods, the Mean Based
method and the Median Based method, apply traditional statistical
tests. The other method, the Low Speed Threshold (LST) method, is
developed in this study. An empirical study based on Automatic
Vehicle Location (AVL) data collected using The Ohio State
University (OSU) Campus Transit Lab (CTL) is conducted to evaluate
the three methods. The indications of
congestion produced by the
three methods are then compared to a priori expectation of
recurrent congestions along the route. The Mean
Based method produces few indications of recurrent
congestion. It
misses space-time cells where recurrent
congestion is expected. The
Median Based method and the LST method produce similar general
patterns in terms of where and when recurrent congestions are
indicated. However, there exist some differences between the Median
Based method and the LST method in terms of the specific locations
where and specific times when recurrent congestions are indicated.
A systematic analysis and comparison based on
the Median Based method and the LST method is conducted. Based on
the empirical analyses and a priori expectation of recurrent
congestions along the route, the LST method seems more appealing
than the Median Based method (and the Mean Based method) for
determining indications of recurrent
congestion. Although the
empirical results produced by the LST method are encouraging, more
research is necessary before concluding that the LST method could
be used to detect recurrent
congestion on a widespread basis. A
sensitivity analysis of the parameters used in this study is
suggested for future research. Other traffic related elements such
as speed limits, bus trip running times, and schedule adherence
might also be utilized to improve the recurrent

▼ The need for
congestion charge is increasing every year due to many reasons mainly the population growth, which affects the number of vehicles on the roads. Therefore, traffic
congestion is a real problem due to both the effects it causes such as delays, fuel consumption and pollution, road rage and emergency vehicles problems, and road space being a limited resource in its nature. Therefore, the more an individual uses the space on the road, the less available for others which leads to making drivers to travel more than they desire and results in loss of time value given an increase on time spent traveling, assuming identical drivers and speeds. Reducing traffic has both economic and environmental advantages but choosing the best method can be crucial in achieving these goals. This paper examines whether
congestion charge is the best policy for reducing traffic
congestion given London and Stockholm experience or better alternatives still exist. In addition, it aims first on examining the results of London and Stockholm
congestion charge, and whether they have succeeded or not on achieving their goals. Therefore, the data is obtained from Transport for London and some other researchers such as Jonathan Leape and Jan Owen Jansson. Second, this paper provides alternatives to the
congestion charge, which some of them don???t suffer from the disadvantages the
congestion charge does such as high cost and regressive in nature. These alternatives will show that better solutions to a traffic
congestion can be found without the need of making lower income residents suffer the higher cost burden or government paying much higher costs than they need to.

▼ With the rapid growth of population in Hong Kong,
the government has been formulating different policies including
housing, social and transport services to cope with the situation.
Undoubtedly one of the major concerns arising from increase of
population is road traffic congestion problem. If no appropriate
measures are to be taken, the effect would be very detrimental,
which not only affect the general public living but also the whole
economy of Hong Kong. As such, the congestion problem has been
seriously addressed by the government since the early era with
numbers of traffic-related policies formulated which aims at
alleviating the congestion problem in the whole territory in Hong
Kong. Over the past decades, transport services have been expanded
in many aspects so as to cope with the ever-increasing population
demand as well as to relieve the congested situation.
Relieving
traffic congestion measures has always been a heated topic in the
policy agenda in the government, as well as within the society.
Over the past years, the HKSAR had been drawing a number of
traffic-related policies to solve the congested problem especially
at those black spots. Also while working closely with different
public transport stakeholders, more diversified regulations or
traffic management measures have also been launched. In this
dissertation, the traffic congestion problem and the traffic
congestion management measures are the main subjects for
discussion. On examining the effectiveness of the policies
concerned, a Tool-kit approach will be adopted. Each policy will be
addressed under the five policy tools which are used as the basics
for reviewing the traffic policies and traffic management measures
formulated by the government from the previous decades till the
current stage. The 5 chosen Policy Tools are Direct Government;
Economic and Social Regulation; Corrective Taxes; Contracting; and
Information. The effectiveness of those measures will be further
evaluated based on the five criteria: Effectiveness; Efficiency;
Equity; Manageability; and Political Legitimacy. Over the past
decades, transport services have been expanded in many aspects so
as to cope with the ever-increasing population demand as well as to
relieve the congested situation. The measures appear to be
effective, but there seems to be room for further improvement.
Apart from the relieving measures to be discussed, there are still
numbers of alternative proposals that can help to alleviate the
congestion problem in Hong Kong. One is the adoption of the
Electronic Road Pricing System and the other alternatives include
better utilization of the RHCs and control the numbers of vehicles
on roads.
While most of the relieving measures carried out in the
past are considered to be effective, that would not be enough as in
view of the increasing population, It’s time for the government to
take into account other alternatives that are considered to be
effective options in solving the congestion problem. While adopting
or implementing any of the proposed option requires…

▼ Unlike traditional TCP/IP-based networks, Delay and Disruption Tolerant Networks (DTNs) may experience connectivity disruptions and guarantee no end-to-end connectivity between source and destination. As the popularity of DTNs continues to rise, so does the need for a robust and low latency routing protocol capable of connecting not only DTNs but also densely populated, dynamic hybrid DTN-MANET. Here we describe a novel DTN routing algorithm referred to as Congestion Avoidance Shortest Path Routing (CASPaR), which seeks to maximize packet delivery probability while minimizing latency. CASPaR attempts this without any direct knowledge of node connectivity outside of its own neighborhood. Our simulation results show that CASPaR outperforms well-known protocols in terms of packet delivery probability and latency while limiting network overhead.

▼ Internet traffic is expected to grow phenomenally over the next five to ten years. To cope with such large traffic volumes, high-speed networks are expected to scale to capacities of terabits-per-second and beyond. Increasing the role of optics for packet forwarding and transmission inside the high-speed networks seems to be the most promising way to accomplish this capacity scaling. Unfortunately, unlike electronic memory, it remains a formidable challenge to build even a few dozen packets of integrated all-optical buffers. On the other hand, many high-speed networks depend on the TCP/IP protocol for reliability which is typically implemented in software and is sensitive to buffer size. For example, TCP requires a buffer size of bandwidth delay product in switches/routers to maintain nearly 100% link utilization. Otherwise, the performance will be much downgraded. But such large buffer will challenge hardware design and power consumption, and will generate queuing delay and jitter which again cause problems. Therefore, improve TCP performance over tiny buffered high-speed networks is a top priority. This dissertation studies the TCP performance in 10Gbps high-speed networks. First, a 10Gbps reconfigurable optical networking testbed is developed as a research environment. Second, a 10Gbps traffic sniffing tool is developed for measuring and analyzing TCP performance. New expressions for evaluating TCP loss synchronization are presented by carefully examining the congestion events of TCP. Based on observation, two basic reasons that cause performance problems are studied. We find that minimize TCP loss synchronization and reduce flow burstiness impact are critical keys to improve TCP performance in tiny buffered networks. Finally, we present a new TCP protocol called Multi-Channel TCP and a new congestion control algorithm called Desynchronized Multi-Channel TCP (DMCTCP). Our algorithm implementation takes advantage of a potential parallelism from the Multi-Path TCP in Linux. Over an emulated 10Gbps network ruled by routers with only a few dozen packets of buffers, our experimental results confirm that bottleneck link utilization can be much better improved by DMCTCP than by many other TCP variants. Our study is a new step towards the deployment of optical packet switching/routing networks.

▼ In this paper, we examine various branch and bound algorithms for a minimum
congestion origin-destination integer multi-commodity flow problem. The problem consists of finding a routing such that the
congestion of the most congested arc is minimum. For our implementation, we assume that all demands are known a priori. We provide a mixed integer linear programming formulation of our problem and propose various new branching rules to solve the model. For each rule, we provide theoretical and experimental proof of their effectiveness. In order to solve large instances, that more accurately portray real-world applications, we outline a path formulation model of our problem. We provide two methods for implementing our branching rules using branch and price.
