▼ Virtualization has become a very popular research topic in recent years. Virtualization is used in varied applications such as e-Learning, business-to-business communication, social networking, computer simulation and enterprise development. These advances are due to the availability of high-speed computers, fiber-optic-enabled internet connections and advanced virtualization programs. However, only a very small amount of research has been conducted, most especially on the performance of virtualization programs. Thus little is known about the performance of the various virtualization programs such as VMware Workstation and VirtualBox. When dealing with virtualization, performance is of primary importance. This thesis reports on the performance of different virtualization programs, such as VMware Workstation 7 and Oracle VM VirtualBox 4 using MS Windows 7 guest-and host-operating systems. The chosen research methodology for this research is a mixed research methodology based on both qualitative and quantitative. A mixed research methodology allows the researcher to easily collect primary data via qualitative methods and then analyze the data using quantitative methods. The main purpose of this study is to find any performance differences in between VMware Workstation and VirtualBox based on Windows 7 guest and host OSs. Various experiments were conducted regarding the performance of VMware Workstation, VirtualBox and Microsoft Windows Virtual PC using Windows 7 and Linux Mint guest OSs and Windows 7 host OS. Findings of the experiments revealed that there are performance differences among VMware Workstation, VirtualBox and Virtual PC. In virtualization, it is generally thought that VMware Workstation is superior to other virtualization programs. However empirical results obtained from this study show that the performance of VMware Workstation and VirtualBox are similar. VMware Workstation has many features but its performance is not very different from VirtualBox. Virtual PC on the other hand is not a reliable product for serious virtualization as it lacks features, performance and support for different host and guest OSs. The overall findings of this study show that VMware Workstation and VirtualBox both meet performance and feature requirements for creating reliable virtual environments. This study opens a new path for research in the area related to performance of virtualization programs. Data gathered from this study was used to make meaningful conclusions in Chapter 6. The conclusion explores possible directions for future research on the performance of virtualization programs. Findings of this study may help businesses to select appropriate virtualization program as part of their information technology infrastructure and thereby benefit from using virtualization technology.

▼ The requirement of high quality services is increasing day by day. So, in order to meet up with this requirement new technologies are being developed one of them being virtualization. The main agenda of introducing virtualization is that though virtualization needs more powerful devices to run the hypervisor, the technique also helps to increase consolidation which makes efficient use of resources like increase in the CPU utilization. The virtualization technique helps us to run more VM’s (Virtual Machine) on the same platform i.e. on the same hypervisor. In virtualization as number of VM’s share the CPU will there be any effect on the performance of TCP with the performance influencing factors of virtualization. While TCP being the most widely used protocol and most reliable protocol can performance of TCP vary if different TCP congestion control mechanism are used in the virtualized environment are the main aims of this research. In this study, we investigate the performance influencing factor of TCP in the virtualized environment and whether those influencing factors have any role to play with the performance of the TCP. Also which TCP congestion control mechanism is best suitable in order to download files when virtualization is used will be investigated by setting up a client-server test bed. The different TCP congestion control mechanism which have been used are CUBIC, BIC, Highspeed, Vegas, Veno, Yeah, Westwood, LP, Scalable, Reno, Hybla. Total download time has been compared in order to know which congestion control algorithm performs better in the virtualized environment. The method that has been used to carry out the research is by experimentation. That is by changing the RAM sizes and CPU cores which are the performance influencing factors in virtualization and then analyzing the total download time while downloading a file by changing the TCP congestion control mechanisms by running a single guest VM. Apart from changing only congestion control mechanisms the other network parameters which effect the performance of the TCP such as Delay have been injected while downloading the file, to match up with the real time scenarios. Results collected include average download time of a file by changing the different memory sizes and different CPU cores. Average Download time for different TCP congestion controls mechanisms with inclusion of the parameter that effects the total download time such as Delay. From the results we got we can see that there is a slight influence on the performance of TCP by the performance influencing factors memory sizes and CPU cores allotted to the VM in the KVM virtualized environment and of all the TCP congestion control algorithms having TCP – BIC and TCP- YEAH performs the best in the KVM virtualized environment. The performance of TCP – LP is the least in the KVM virtualized environment.

peer-reviewed

Trusted Computing is a relatively new approach to computer security in which a system should be permanently maintained in a well-defined state - and therefore it will reside in a trustworthy state. The word "trustworthy" in this context means that the system always behaves in a specific way as defined by the platform manufacturer and/or the administrator/owner. A key element of this approach is to employ a security module, which is implemented in hardware, and which is tied to the platform so as to serve as a trust anchor. Based on that ’root of trust’ and other features, an effective security architecture is proposed in this research. Virtualization techniques, which were formerly developed for server consolidation, cost reduction, and conservation of energy are now gaining more and more interest in the field of trusted computing. Virtualization can greatly enhance the security of a system by isolating applications, or even whole operating systems, by splitting the computer system into smaller parts, whose integrity can be more easily assured. This project is concerned with the development of a system that will effectively combine the isolation features of the virtualization schemes with a state-of-the-art hardware security module. This system will provide reliable protection against sophisticated software-based attacks and will withstand elementary hardware-based attacks. The building block approach of this proposed security architecture makes sure that many different application fields can archive a high level of security by combining the appropriate components. The research examines some emerging approaches to computer security and proposes a novel security architecture based on a hardware trust anchor. An experimental system is developed to provide a ’proof-of-concept’ model for evaluation. The target application area for the architecture is the embedded computing space, in particular x86 based architectures. The selection of hardware elements and the choice of hypervisor are discussed and justified. The assumptions on the features of the architecture are evaluated and validated in the context of potential security improvements. Future research in this niche area is proposed.

▼ The Internet of the Things (IoT) is evolving rapidly, and its significant impacts are expected to affect many application domains. Challenges in areas that humans have been striving to understand, measure, or predict—such as wildlife, healthcare, or environmental hazards—are likely to be addressed by the time IoT emerges. The underlying elements of IoT are wireless sensor networks (WSNs), which consist of a large number of sensor nodes. In the IoT sphere, sensor nodes represent tangible objects—Things—that monitor changes, collect information, and eventually send it through the Internet to a recipient party. Inherently, however, a wireless sensor node relies on limited computational resources with a limited power source. These undesirable qualities result in a low level of dependability. This research explores the viability of applying the unfolding network programmability concepts to overcome survivability obstacles in WSNs and the IoT. In particular, it examines the viability of software-defined networking (SDN) in network lifetime maximisation, failure detection, and failure recovery problems in WSNs. Software-defined networking is a new network programmability concept that separates the traditionally-tied control and data planes. It offloads the route computations and management from network devices to a logically centralised controller. This separation directly leads to better allocation of computational resources for the network nodes and allows endless orchestration possibilities for the controller. This thesis proposes an SDN-based solution to increase the survivability and resilience of WSN environments. Following an approach that conforms with the centralised nature of SDN environments and considers the limited resources of the WSN. A routing algorithm based on A-star was developed for WSNs, then deployed within an SDN environment to maximise the network lifetime. Apart from finding the path with the lowest energy burden, the algorithm offloads most of the control traffic from sensor nodes to the controller. This algorithm resulted in improved resource utilisation among the nodes due to plane decoupling. Additionally, it increased the lifetime of the network by 22.6% compared to the widely explored LEACH protocol. This thesis also investigates different failure detection and recovery practices in the SDN architecture. The simulation results show that adopting bidirectional forwarding detection (BFD) with the asynchronous echo mode for WSN in an SDN environment reduces control traffic for failure detection to between 27% and 48%. The thesis also evaluates the performance of multiple recovery approaches when adopting the premises of SDN. The simulation results indicate that path protection, using group tables from the OpenFlow protocol, has a recovery time up to eight times shorter than the restoration time. The results of the study reveal that using protection as a failure recovery technique significantly reduces control traffic overhead.

Mestrado em Engenharia Informática

In an era marked by the so-called technological revolution, where computing power has become a critical production factor, just like manpower was in the industrial revolution, very quickly this dispersal of computing power for numerous facilities and sites became unsustainable, both economically as well in terms of maintenance and management. This constringency led to the need of adopting new strategies for the provision of information systems equally capable but in a more consolidated way, while also increasing the desired levels of the classic set of information assurances: availability, confidentiality, authenticity and integrity. At this point enters a topic not as new as it may seem, virtualization, which after two decades of oblivion presents itself as the best candidate to solve the problem technology faces today. Throughout this thesis, it will be explained what this technology represents and what approach should be taken in the evolution of a systems architecture classical model into a model based in optimization, high availability, redundancy and consolidation of information communications and technology, using networks and systems virtualization. A number of good management principles to adopt will also be taken into account to ensure quality standards in providing services, culminating in a practical application of this model to the infrastructure of the company Metro do Porto, SA. Briefly, this document can almost be classified as a step by step manual for the understanding and implementation of this model, transversal to any infrastructure without extremely particular needs or constraints which derail conversion.

Numa era marcada pela chamada revolução tecnológica, em que o poder de computação se tornou um factor crítico de produção, tal como a mão-de-obra o foi na revolução industrial, rapidamente esta dispersão do poder de computação por inúmeros equipamentos e locais tornou-se insustentável, quer ao nível económico como de manutenção e gestão. Este constrangimento levou à necessidade de adopção de novas estratégias para a disponibilização de sistemas de informação igualmente capazes mas de forma mais consolidada, procurando simultaneamente aumentar os níveis desejáveis do clássico paradigma dos factores a garantir na informação: disponibilidade, confidencialidade, autenticidade e integridade. É neste ponto que entra um tema não tão novo como parece, a virtualização, que após duas décadas de esquecimento se apresenta como o maior candidato à resolução do problema que a tecnologia enfrenta. Ao longo desta tese, será explicado o que esta tecnologia representa e qual a abordagem a ter na evolução de um modelo clássico de arquitectura de sistemas para um modelo baseado em optimização, alta disponibilidade, redundância e consolidação de tecnologias de informação e comunicações com recurso à virtualização de redes e sistemas. Serão igualmente tidos em conta um número de bons princípios de gestão a adoptar de forma a garantir parâmetros de qualidade na…

▼ Cloud computing has emerged as an economically attractive utility model for computational resources. An increasing number of industries, from businesses to governments, are embracing cloud computing. However, the economic benefits of the cloud computing model come at a price: the loss of control over how services and applications can use computing resources. In other words, cloud computing is fundamentally provider-centric. Cloud providers (the providers of computational resources), not cloud users (the consumers of computational resources), dictate rules and policies governing how computational resources can be used. For large enterprise application workloads, adhering to cloud provider rules and policies may be prohibitive. This dissertation explores the question: how can large enterprise workloads efficiently utilize and control computational resources from a variety of providers in the cloud computing model? The main contributions of this dissertation relate to a fundamental change to the cloud computing model. Instead of a provider-centric model, we propose a user-centric model in which the cloud user can maintain control over how computational resources obtained from cloud providers can be used. We have devised a new abstraction, called cloud extensibility, to enable the implementation of provider-level functionality by cloud users. Leveraging cloud extensibility, we describe steps towards a user-centric cloud computing model that grants cloud users-including large enterprises-control over resources obtained from one or more cloud providers. We call this new model the supercloud model. More specifically, we focus on three key areas in which current providercentric cloud computing models do not expose the necessary control or lack the features to support large enterprise workloads without significant reconfiguration effort. First, clouds are not interoperable, restricting workloads to a single provider and hindering incremental migration to the cloud. Second, clouds lack support for complex enterprise network configurations, including flow policies between application components and low-level network features (e.g., IP addresses, multicast, VLANs). Finally, high utilization of cloud resources cannot be applied through techniques like oversubscription, and existing techniques do not apply well to common workload patterns. We subsequently make three contributions, embodied in the design, implementation and evaluation of three systems that leverage cloud extensibility. Cloud extensibility itself is instantiated in the first system, a nested virtualization layer called the Xen-Blanket. The Xen-Blanket additionally enables cloud interoperability by homogenizing existing cloud interfaces and services. The second system, VirtualWire, provides a virtual network abstraction to support complex enterprise networks in which the cloud user manages the network control logic. Finally, we present Overdriver, a system that enables high resource utilization through memory oversubscription and the handling of the resulting-often… Advisors/Committee Members: Weatherspoon, Hakim (chair), Pond, Steven F.

▼ Successful realization of practical computer security improvements requires an understanding and insight into the system's security architecture, combined with a consideration of end-users' needs as well as the system's design tenets. In the case of Android, a system with an open, modular architecture that emphasizes usability and performance, acquiring this knowledge and insight can be particularly challenging for several reasons. In spite of Android's open source philosophy, the system is extremely large and complex, documentation and reference materials are scarce, and the code base is rapidly evolving with new features and fixes. To make matters worse, the vast majority of Android devices in use do not run the open source code, but rather proprietary versions that have been heavily customized by vendors for product differentiation. Proposing security improvements or making customizations without sufficient insight into the system typically leads to less-practical, less-efficient, or even vulnerable results. Point solutions to specific problems risk leaving other similar problems in the distributed security architecture unsolved. Far-reaching general-purpose approaches may further complicate an already complex system, and force end-users to endure significant performance and usability degradations regardless of their specific security and privacy needs. In the case of vendor customization, uninformed changes can introduce access control inconsistencies and new vulnerabilities. Hence, the lack of methodologies and resources available for gaining insight about Android security is hindering the development of practical security solutions, sound vendor customizations, and end-user awareness of the proprietary devices they are using. Addressing this deficiency is the subject of this dissertation. New approaches for analyzing, evaluating and understanding Android access controls are introduced and used to create an interactive database for use by security researchers as well as system designers and end-user product evaluators. Case studies using the new techniques are described, with results uncovering problems in Android's multiuser framework and vendor-customized System Services. Finally, the new insights are used to develop and implement a novel virtualization-based security architecture that protects sensitive resources while preserving Android's open architecture and expected levels of performance and usability.

▼ Cloud services are currently being extensively used for server hosting, data storage, scientific and research purposes. Virtualization technology is an essential element for these services. Virtualization enables the creation of multiple virtual instances on physical or hardware infrastructure. Network virtualization is a recent advancement in this field through which virtual networks can be created over real physical networks (also called as substrate networks). Such virtual networks facilitate testing and quick deployment of new technologies, better utilization of hardware and provide more flexibility to users. A crucial element of network virtualization is the stage in which the virtual networks are created on the substrate network. This process is of critical nature as the number of virtual networks that are created on the substrate are high. Hence the placement of these virtual networks needs to be done in a strategic way. The creation of virtual networks on a substrate network is referred to as Virtual network embedding. Determining the best way to place or create multiple virtual networks on a substrate network while satisfying a given set of constraints is referred to as Virtual network embedding problem. The technique or algorithms used to solve this problem are known as virtual network embedding algorithms. In this thesis we evaluate and compare six virtual network embedding algorithms for embedding short-lived virtual networks on substrate networks with fat-tree topology and UUNET topology. We discuss different metrics to evaluate the performance of embedding algorithms and compare the algorithms based on these metrics. In particular, we examine the probability of success of embedding a virtual network, average substrate path length and the distribution pattern of virtual networks in the substrate network for six different algorithms. The aim of this thesis work is to compare the performance of virtual network embedding algorithms, observe the nuances of the approaches that contribute to optimal results and investigate the embedding for the case of short-lived virtual networks.

▼ Graphics Processing Units (GPUs) are being adopted in many computing facilities given their extraordinary computing power, which makes it possible to accelerate many general purpose applications from different domains. However, GPUs also present several side effects, such as increased acquisition costs as well as larger space requirements. They also require more powerful energy supplies. Furthermore, GPUs still consume some amount of energy while idle and their utilization is usually low for most workloads. In a similar way to virtual machines, the use of virtual GPUs may address the aforementioned concerns. In this regard, the remote GPU virtualization mechanism allows an application being executed in a node of the cluster to transparently use the GPUs installed at other nodes. Moreover, this technique allows to share the GPUs present in the computing facility among the applications being executed in the cluster. In this way, several applications being executed in different (or the same) cluster nodes can share one or more GPUs located in other nodes of the cluster. Sharing GPUs should increase overall GPU utilization, thus reducing the negative impact of the side effects mentioned before. Reducing the total amount of GPUs installed in the cluster may also be possible. In this dissertation we enhance one framework offering remote GPU virtualization capabilities, referred to as rCUDA, for its use in high-performance clusters. While the initial prototype version of rCUDA demonstrated its functionality, it also revealed concerns with respect to usability, performance, and support for new GPU features, which prevented its used in production environments. These issues motivated this thesis, in which all the research is primarily conducted with the aim of turning rCUDA into a production-ready solution for eventually transferring it to industry. The new version of rCUDA resulting from this work presents a reduction of up to 35% in execution time of the applications analyzed with respect to the initial version. Compared to the use of local GPUs, the overhead of this new version of rCUDA is below 5% for the applications studied when using the latest high-performance computing networks available.; Las unidades de procesamiento gráfico (Graphics Processing Units, GPUs) están siendo utilizadas en muchas instalaciones de computación dada su extraordinaria capacidad de cálculo, la cual hace posible acelerar muchas aplicaciones de propósito general de diferentes dominios. Sin embargo, las GPUs también presentan algunas desventajas, como el aumento de los costos de adquisición, así como mayores requerimientos de espacio. Asimismo, también requieren un suministro de energía más potente. Además, las GPUs consumen una cierta cantidad de energía aún estando inactivas, y su utilización suele ser baja para la mayoría de las cargas de trabajo. De manera similar a las máquinas virtuales, el uso de GPUs virtuales podría hacer frente a los inconvenientes mencionados.

▼ The development of virtualization started in 1960, when VMware introduced partitioning of large mainframes for better hardware utilization. (Virtualization History, 2010) Since then virtualization has matured and been adopted to a wide extent in the industry. Recent developments include branching into areas of server virtualization, storage and application virtualization and, very recently, desktop virtualization. Desktop virtualization has so far been through two models: the Client hosted model, which is typically operated from the user’s workstation using Windows Virtual PC; and the VMware workstation or Java Virtual Machine (VM). However, recently a third model has emerged, called the server hosted model or Hosted virtual desktop (HVD), which is a virtualized form of desktop (VM) delivered to users from the cloud infrastructure. In other words virtualization in computing has progressed to an extent where desktops can be virtualized and accessed from anywhere. The server hosted model has already surpassed 1% market share of the worldwide professional PC market, with estimates indicating that this is a rapidly growing area. This study investigates the adequacy of current digital forensic procedures on hosted virtual desktops (HVDs) as there does not appear to be specific methods of locating and extracting evidences from this infrastructure. Using the Forensic Iterative Development Model (FIDM), HVDs deployed in private cloud were simulated to reflect three different computer crime (quasiexperimental) scenarios. It was found that current digital forensic procedures may not be adequate for locating and extracting evidence, since the infrastructure in scenario 2 and 3 introduces complications such as non-persistent disk modes and segregating data in a multitenant environment. However in scenario 1, findings illustrate that all standard investigation techniques can be followed as a result of the persistent user environment. Furthermore, suggestions are made to extend the current research in the areas of techniques to acquire virtual machines from hypervisors, hashing evidence and forensic readiness in environments consisting HVDs.

This master’s thesis explains why certain network services are difficult to provision and configure using IT automation and cloud orchestration software. An improvement is proposed and motivated. This proposed improvement enables network operators to define a set of data models describing how to provision and interconnect a set of Virtual Network Functions (VNFs) (and possibly existing physical network functions) to form networks. Moreover, the proposed solution enables network operators to change the configuration at runtime. The work can be seen as a step towards self managing and auto scaling networks. The proposed approach is compared to a well known cloud management system (OpenStack) in order to evaluate if the proposed approach decreases the amount of time needed for network operators to design network topologies and services containing VNFs. Data is collected through observations of network operators, interviews, and experiment. Analysis of this data shows that the proposed approach can decrease the amount of time required for network operators to design network topologies and services. This applies if the network operators are already acquainted with the data modeling language YANG. The amount of time required to provision VNFs so that they respond to connections can also be decreased using the proposed approach. The proposed approach does not offer as much functionality as OpenStack, as it is limited to VNF scenarios.

Denna masteruppsats förklarar varför vissa nätverkstjänster är svåra att skapa och konfigurera med IT-automationsverktyg och mjukvara för molnorkestrering. En förbättring föreslås och motiveras. Den föreslagna förbättringen tillåter nätverksoperatörer att definiera en mängd datamodeller, för att beskriva hur Virtuella Nätverksfunktioner (VNF:er) skall instantieras och kopplas ihop till nätverkstjänster. Dessutom tillåter lösningen nätverksoperatörer att ändra konfiguration under tiden nätverken hanterar trafik. Arbetet kan ses som ett steg mot självhanterande och automatiskt skalande nätverk. Den föreslagna lösningen jämförs med ett välkänt molnorkestreringsverktyg (OpenStack) för att utvärdera om den föreslagna lösningen sänker mängden tid som nätverksoperatörer behöver för att designa nätverkstopologier och tjänster som innehåller VNF:er. Data samlas in genom observationer av nätverksoperatörer, intervjuer, och experiment. Analys av datan visar att den föreslagna lösningen kan minska tiden som behövs för att designa nätverkstopologier och tjänster. Fallen där detta är applicerbart, är när VNF:er närvarar i nätverk. Dessa är enklare att skapa, konfigurera, och ändra under tiden de exekverar, med den föreslagna metoden. Detta kräver också att nätverksoperatören är bekant med datamodelleringsspråket YANG. Tiden det tar att provisionera VNF:er, tills dess att de svarar till anslutningar, kan sänkas med hjälp av den föreslagna metoden. Den förslagna metoden erbjuder väsentligt begränsad funktionalitet jämfört med OpenStack, den fokuserar på att hantera…

▼ While one always works to prevent attacks and failures, they are inevitable and situational awareness is key to taking appropriate action. Monitoring plays an integral role in ensuring reliability and security of computing systems. Infrastructure as a Service (IaaS) clouds significantly lower the barrier for obtaining scalable computing resources and allow users to focus on what is important to them. Can a similar service be offered to provide on-demand reliability and security monitoring? Cloud computing systems are typically built using virtual machines (VMs). VM monitoring takes advantage of this and uses the hypervisor that runs VMs for robust reliability and security monitoring. The hypervisor provides an environment that is isolated from failures and attacks inside customers’ VMs. Furthermore, as a low-level manager of computing resources, the hypervisor has full access to the infrastructure running above it. Hypervisor-based VM monitoring leverages that information to observe the VMs for failures and attacks. However, existing VM monitoring techniques fall short of “as-a-service” expectations because they require a priori VM modifications and require human interaction to obtain necessary information about the underlying guest system. The research presented in this dissertation closes those gaps by providing a flexible VM monitoring framework and automated analysis to support that framework. We have developed and tested a dynamic VM monitoring framework called Hypervisor Probes (hprobes). The hprobe framework allows us to monitor the execution of both the guest OS and applications from the hypervisor. To supplement this monitoring framework, we use dynamic analysis techniques to investigate the relationship between hardware events visible to the hyper-visor and OS constructs common across OS versions. We use the results of this analysis to parametrize the hprobe-based monitors without requiring any user input. Combining the dynamic VM monitoring framework and analysis frameworks allows us to provide on-demand hypervisor based monitors for cloud VMs. Advisors/Committee Members: Iyer, Ravishankar K (advisor), Kalbarczyk, Zbigniew T (advisor), Iyer, Ravishankar K (Committee Chair), Bailey, Michael D (committee member), Campbell, Roy H (committee member), Hwu, Wen-Mei W (committee member).

▼ A promising solution to overcome the Internet ossification is network virtualization in which Internet Service Providers (ISPs) are decoupled into two tiers: service providers (SPs), and infrastructure providers (InPs). The former maintain and customize virtual network(s) to meet the service requirement of end-users, which is mapped to the physical network infrastructure that is managed and deployed by the latter via the Virtual Network Embedding (VNE) process. VNE consists of two major components: node assignment, and link mapping, which can be shown to be NP-Complete. In the first part of the dissertation, we present a path-based ILP model for the VNE problem. Our solution employs a branch-and-bound framework to resolve the integrity constraints, while embedding the column generation process to effectively obtain the lower bound for branch pruning. Different from existing approaches, the proposed solution can either obtain an optimal solution or a near-optimal solution with guarantee on the solution quality. A common strategy in VNE algorithm design is to decompose the problem into two sequential sub-problems: node assignment (NA) and link mapping (LM). With this approach, it is inexorable to sacrifice the solution quality since the NA is not holistic and not-reversible. In the second part, we are motivated to answer the question: Is it possible to maintain the simplicity of the Divide-and-Conquer strategy while still achieving optimality? Our answer is based on a decomposition framework supported by the Primal-Dual analysis of the path-based ILP model. This dissertation also attempts to address issues in two frontiers of network virtualization: survivability, and integration of optical substrate. In the third part, we address the survivable network embedding (SNE) problem from a network flow perspective, considering both splittable and non-splittable flows. In addition, the explosive growth of the Internet traffic calls for the support of a bandwidth abundant optical substrate, despite the extra dimensions of complexity caused by the heterogeneities of optical resources, and the physical feature of optical transmission. In this fourth part, we present a holistic view of motivation, architecture, and challenges on the way towards a virtualized optical substrate that supports network virtualization.

▼ Digital video processing demands have and will continue to grow at unprecedented rates. Growth comes from ever increasing volume of data, demand for higher resolution, higher frame rates, and the need for high capacity communications. Moreover, economic realities force continued reductions in size, weight and power requirements. The ever-changing needs and complexities associated with effective video processing systems leads to the consideration of dynamically reconfigurable systems. The goal of this dissertation research was to develop and demonstrate the viability of integrated parallel processing system that effectively and efficiently apply pre-optimized hardware cores for processing video streamed data. Digital video is decomposed into packets which are then distributed over a group of parallel video processing cores. Real time processing requires an effective task scheduler that distributes video packets efficiently to any of the reconfigurable distributed processing nodes across the framework, with the nodes running on FPGA reconfigurable logic in an inherently Virtual' mode. The developed framework, coupled with the use of hardware techniques for dynamic processing optimization achieves an optimal cost/power/performance realization for video processing applications. The system is evaluated by testing processor utilization relative to I/O bandwidth and algorithm latency using a separable 2-D FIR filtering system, and a dynamic pixel processor. For these applications, the system can achieve performance of hundreds of 640x480 video frames per second across an eight lane Gen I PCIe bus. Overall, optimal performance is achieved in the sense that video data is processed at the maximum possible rate that can be streamed through the processing cores. This performance, coupled with inherent ability to dynamically add new algorithms to the described dynamically reconfigurable distributed processing framework, creates new opportunities for realizable and economic hardware virtualization.'
