▼ The open all-digital communications protocol FOUNDATION Fieldbus offers a wide range of benefits to process control systems through data reliability, diagnostics, interoperability, and distribution of controls to an unprecedented level. However, lack of media redundancy on its H1 networks can compromise the availability of view and control of a critical process. In this thesis a novel approach is proposed to add fault tolerance by achieving media redundancy on H1 networks. It presents an H1 topology framework capable of detecting and handling a break in the network to allow control and communication to continue uninterrupted. A test network with a functional prototype was constructed to evaluate real-world control application in fully redundant settings. Results showed that continuity of control and supervisory view to the process remained uninterrupted when a cable break is induced, resulting in a fault tolerant H1 network.

▼ Because of the high bandwidth demand, the optical fabric becomes very important in Internet infrastructure. The switching technologies also pose unique challenges for optical fabric. The optical infrastructure has to face all these challenges created by advanced Internet technologies as well as the challenge of scalability of optical fabric. This thesis proposes a novel stackable structure of optical fabric which is easy to expand and has low installation cost.
In this work, the concept of reconfigurable scheduler for stackable optical fabric has been introduced, and the architecture of this scheduler has been designed. The scheduler considers intrinsic connectivity of physical layers as well as the service requirements of the application layer. In order to verify the design, the prototype was designed and realized on a FPGA board. For evaluating the cost saving of the proposed stackable optical fabric, a general cost model was developed and compared with the flat optical fabric. The stackable fabric was observed to be the trade-off between cost and performance.

▼ This thesis describes a hybrid optical/electronic network architecture that overcomes the limitations of using only modified commodity hardware in such networks, and is easy for industry to adopt. Test results show significant performance improvements when the proposed system is added to a highly oversubscribed electronic network and good performance with no detrimental effects when the system is added to a traditional electronic network that is not oversubscribed. This allows for greater oversubscription ratios in the electronic network and therefore cheaper and less complex hardware. The primary contributions of this work include a method of seamlessly integrating optical switching into an existing network using custom hardware, a research platform that allows greater flexibility in the analysis of hybrid optical/electronic networks, and a software platform for simulating such networks.

▼ Unmanned flight vehicles have received considerable attention from researchers in multiple areas. They can be used as a research platform to evaluate new concepts in different fields including control theory, real-time system, robotics, and navigation. One of the most typical designs for unmanned flight vehicle is Quadcopter. Although quadcopters are mechanically simple, controlling them is a challenging task because the system is highly non-linear and unstable.
In this thesis, the mathematical model of a basic quadcopter is presented. Full State Feedback control method and PID control method are proposed and applied to the quadcopter model. In order to verify the effectiveness of the designed controller, a simulation is also provided. The results show that both controllers can be both effective with a good set of initial parameters.

▼ Classical cryptography protocols are becoming vulnerable due to increasing computer power. However, optical fibers provide another method of securing the communication, by means of quantum cryptography. The concept of encoding the information in polarization states of photons has proven to be unconditionally secure. A few protocols have been proposed but the practical implementation of most of them have posed complications.
In this thesis work, a Quantum control protocol is proposed to safeguard a secure transaction over an optical network. The protocol provides a robust re-configurable architecture capable of incorporating several promising quantum cryptography protocols. The quantum control protocol has been prototyped on a FPGA test bed. The prototype yielded an error free transaction across the network. Thus, validating the claim of a practically realizable secure system.

▼ With the spread of the cloud-computing today, local networks have been gradually developed to have better support for cloud applications. For a specific sub-network, different ports may have different requirements. Traditional symmetric router assumes uniformed resource distribution among all ports, overestimating resources needed at some ports. This thesis proposes an innovative Asymmetric Multi-Channel edge router, which supports non-uniformed port distribution based on the clients’ demand.
In this work, the concept of Asymmetric Multi-Channel (AMC) router is introduced, and the architecture of the AMC router is designed. In order to verify the cost saving of the proposed router, a general cost model is developed to provide cost comparison between the traditional symmetric router and the proposed AMC router. A reconfigurable scheduling scheme is proposed, which can achieve constant-time (O(1)) performance with the introduction of pipeline paralleled comparators and updaters. A configuration strategy is proposed for the most suitable resource distribution.

▼ Dense Wavelength Division Multiplexing (DWDM) allows hundreds of wavelength channels to be carried in a single optical fiber, at the rate of 40 Gb/s and beyond, and is the most promising solution for next generation networks. However, an all-optical-packet
switched DWDM network cannot be practically realized due to limitations on optical technologies.
We present a DWDM multimode router architecture, which supports electronic packet switching, optical circuit switching, and optical burst switching modes on the same router platform. The multimode router is capable of dynamically reconfiguring wavelengths to operate in the desired switching modes. This approach allows short messages to
be switched electronically using packet switching, while allowing the majority of the data
transfer (e.g., video) to pass core routers optically. It greatly reduces the need for expensive
Optical-Electrical-Optical (O-E-O) converters.
In this work, we have proposed the design and also analyzed the multimode router architecture. We analyzed the cost, performance, and energy consumption of the multimode
router. More specifically, we developed an analytical cost model to show that the multimode router is cost effective across a wide range of technology factors. A novel dynamic resource allocation method called Predictive Need-based Optimized Resources Allocation (PNdORA) was proposed. The scheme predicts the need of each optical port in the future time frame, and allocates O-E-O converter pairs in real-time. Results indicate
that this method improves performance of the multimode router, by several orders of
magnitude, under abruptly varying traffic. We have also developed an energy consumption model of the multimode router, and compared it with existing models. We propose the use of MEMS actuated mirrors in the optical switching fabric, as these consume far less energy than any other optical switching fabrics. We show that by deploying the strengths of electronic packet switching, optical circuit switching, and optical burst switching, the multimode router is a cost effective candidate for future bandwidth needs while having a low carbon footprint.

▼ The Internet today is dominated by more and more multimedia applications such as HD videos, VoIP services and online gaming, which have driven the bandwidth demand. Dense Wavelength Division Multiplexing (DWDM) enables hundreds of wavelength channels to be transmitted within one physical optical fiber with rates at 100Gbps per channel and beyond. This is the most promising solution to build the next generation networks. However, the all-optical DWDM network is not practical right now due to the limitations on optical technologies. On the other hand, new services such as cloud computing produce heterogeneous data traffic, which has different Quality-of-Service (QoS) requirements for different applications. A reconfigurable multimode switching router is positioned as a service platform to support the next generation networks in this dissertation. The reconfigurable multimode switching router can perform electronic packet switching, optical circuit switching and optical burst switching concurrently with dynamic reconfiguration capability.
In this work, a mathematical model to analyze the blocking probability of the multimode router with full wavelength conversion and partial wavelength conversion is presented. The model provides an efficient way to evaluate performance of the multimode router under various traffic scenarios, and gives insights into traffic sharing and queueing in the multimode router. In order to enable packet level traffic managements in optical networks, a packetized DWDM network is proposed to provide a better QoS guarantee. A dynamical resource allocation scheme is proposed to assign bandwidth to different flows with absolute end-to-end delay guarantees. Results show the efficiency of the proposed QoS provisioning method to assign the appropriate amount of bandwidth to the traffic to meet its QoS requirements. An Open Channel multimode switching network is designed to improve the QoS support. Open channels can be established dynamically based on requests and real-time traffic conditions. A dynamic online routing scheme is applied to create open channels using the traffic information at each hop. Numerical results demonstrate the efficiency of the open channel approach. The-state-of-the-art research and commercial network architectures are reviewed, and the reconfigurable multimode switching router is considered as a promising service platform to support new network paradigms and services.

▼ In the era of information explosions, the size and complexity of data is expanding dramatically. To meet this requirement, lots of efforts have been made in both the time domain and the frequency domain. In the wireless communication area, the prevalent Time-Division Multiple-Access (TDMA) used in second generation global system for mobile communications (GSM) network is a good example of manipulating the signal in the time domain in order to share bandwidth over time. Orthogonal frequency-division multiplexing (OFDM) on the other hand, utilizes orthogonal sub-carrier signals to carry data on parallel data channels, achieving high spectrum efficiency. On the optical link side, the Dense Wavelength Division Multiplexing (DWDM) is a promising solution to meet the requirement. By multiplexing different carrier wavelengths onto one single strand of fiber, the link bandwidth can increase exponentially.
But the all optical DWDM network is hard to utilize due to technology limitations. This dissertation aims at solving the current limitations on all-optical network from both switching technology and network architecture aspects. From the perspective of switching technologies, the DWDM Multi-Mode router provides an integrated platform to support three different switching technologies simultaneously. The dynamic reconfiguration capability in DWDM Multi-Mode enables the bandwidth sharing among three switching methods which increases the channel utilization. From the perspective of the applications, the Application-Aware (A2) optical network features the reverse data path reservation is a good candidate of asymmetric traffic transmission. By creating alternative switching technique towards optical switching network, the A2 optical scheduler eliminates the setup latency problem in traditional optical router. At the same time, the path reservation can be changed in real-time, increasing the probability of packets delivery.
The 3-D switching opened another dimension in optical network to reduce traffic blocking. A dynamical resource allocation scheme is proposed to assign bandwidth for different traffic flows. The hardware experiments showed the feasibility of the proposed 3-D switching and it is expected to serve as a building block of future optical networks.
