Available in PDF, EPUB and Kindle. Book excerpt: Optical Burst Switching (OBS) is a prospective networking technology that can carry mankind to the next generation information superhighways. Networking services like HDTV, video-conferencing, grid computing and other bandwidth-hungry applications can see a new day with OBS potentially providing humongous throughput and utilization at the lower layers. The implementation benefits of OBS over the pure-breed optical packet switching (OPS) makes it a favorable technology for both academia and industry to ponder upon. Like any other technology growing through its infancy, OBS faces several challenges and provides several open research topics for researchers. In this dissertation, a few burning issues which we think are important are identified and solutions for them are proposed. In the first part, we propose an implementation of an OBS metropolitan area ring network. We propose several access protocols to efficiently transport different classes of traffc across the ring nodes. Three classes of traffic are identified, one of which has stringent end-to-end delay requirements and the other two require minimal or zero burst loss. Access protocols based on Token and acknowledgement techniques are considered and then developed to accommodate the above requirements. Extensive simulations are then carried out to depict the behaviour of each of the protocols and to verify that our objectives are met. In the second part, we propose a congestion ontrol architecture for OBS mesh networks. Congestion in OBS networks leads to extensive burst losses due to bufferless nature of these networks. We dentify several promising techniques which can be investigated upon to solve the congestion problem. We finally propose a congestion control architecture with multi-tier congestion avoidance schemes for different classes of traffic. In the third part, we present both an analytical solution and a numerical approach for modeling limited-range wavelength conversion in an OBS switch. The analytic.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the current state of the technology, the Optical Burst Switched (OBS) architecture is a practical optical switching solution for the optical networks. In OBS, the user data is transmitted in variable size data units, called bursts, which travel as an optical signal along the entire route. The control information for each burst is transmitted prior to its corresponding burst and it is electronically processed at each hop along the route. The dynamic nature of OBS allows for network adaptability and scalability, which makes it very suitable for the transmission of bursty traffic. In this thesis we study and analyze the performance of OBS networks. We consider the case when the bursts are large enough to simultaneously hold wavelengths on multiple links along the route. Since the size of the bursts varies and the link distance between two adjacent network nodes also varies, a burst may simultaneously occupy wavelengths on a variable number of links as it travels from its source to its destination. As the burst propagates through the network, it dynamically acquires and releases wavelengths from link to link. In this thesis, we propose queueing network models that feature dynamic simultaneous link possession and analyze them in order to obtain the end-to-end burst loss probabilities. This thesis is structured into five parts. In the first part, we describe the Optical Burst Switch architecture and summarize its main design components. In the second part, we define and motivate the simultaneous link possession problem. In the third part, we study an OBS network where the bursts are large enough to simultaneously hold wavelengths on one or two consecutive links. In the fourth part of this thesis, we analytically study an OBS network with simultaneous link possession and a very large number of wavelengths per link. In the fifth part, we address the problem of how to analytically evaluate the performance of OBS networks when the arrival traffic is bursty.

Abstract: Abstract of thesis entitled " Novel Resource Allocation Schemes in Optical Burst Switching Networks" submitted by Li Guangming for the degree of Doctor of Philosophy at The University of Hong Kong in September 2006 Optical communication systems will play an important role in the next generation network. At present, there are three major candidate solutions for optical communication systems based on wavelength-division multiplexing (WDM) technology: optical circuit switching (OCS), optical packet switching (OPS), and optical burst switching (OBS). Given the limitations of current optical processing capability and lack of practical optical buffers, OBS is considered to be the top choice for the next generation network in the near term since it is more efficient than OCS in terms of wavelength utilization efficiency and it does not require the technological breakthroughs needed to make OPS a reality. The main objective of our research is to develop novel resource allocation schemes to improve network performance in OBS networks. We start with a comprehensive review of existing research in OBS networks. We then present the relationships between network performance and network parameters in OBS networks, and provide the guidelines for choosing variousreservation schemes and scheduling algorithms in OBS networks. Switching constraint resolutions are proposed to alleviate the negative effects due to switching configuration time. Next, we propose a window-based reservation scheme and the use of regional controllers to reduce burst contentions. The advantage of using regional controllers and the window-based reservation scheme is that they can be implemented in a generic OBS network and only increase the electronic processing. Simulations show that the proposed schemes can improve network performance even if the network is heavily loaded. Then, we propose a straightforward reservation scheme, dynamic offset, in OBS networks with fiber delay lines (FDLs). Simulations show that the proposed scheme has lower loss probability than the general scheme. We further study the problem of dimensioning fiber delay lines and present the impacts of their parameters on network performance. Finally, we propose a delayed reservation decision scheme in OBS networks with FDLs. Simulations show that the proposed scheme can improve network performance compared with existing schemes.

Available in PDF, EPUB and Kindle. Book excerpt: Optical WDM networking technology is spearheading a bandwidth revolution in the networking infrastructure being developed for the next generation Internet. Rapid advances in optical components have enabled the transition from point-to-point WDM links to all-optical networking. Optical WDM Networks: Principles and Practice presents some of the most important challenges facing the optical networking community, along with some suggested solutions. Earlier textbooks in optical networking have a narrower perspective, and rapidly advancing research has created the need for fresh and current information on problems and issues in the field. The volume editors and contributing authors have endeavoured to capture a substantial subset of the key problems and known solutions to these problems. All of the chapters are original contributions from leading international researchers. The chapters address a wide variety of topics, including the state of the art in WDM technology, physical components that make up WDM fiber-optic networks, medium access protocols, wavelength routed networks, optical access networks, network management, and performance evaluation of wavelength routing networks. The chapters also survey critical points in past research and tackle more recent problems. Practitioners and network product engineers interested in current state-of-the-art information beyond textbook-type coverage, and graduate students commencing research in this area, will appreciate the concise - and pertinent - information presented herein.
