Book excerpt: Wavelength division multiplexing (WDM) has emerged as a viable solution to the increasing bandwidth demands of current backbone networks. Traffic grooming allows the resources available on a single wavelength to be utilized by multiple traffic streams. These networks will support large amounts of traffic from various sources. In view of this, our research focuses on the analysis of such types of networks, and in particular on a traffic-groomed tandem optical network that supports multiple sources each with unique resource requirements. We developed a decomposition algorithm for the analysis of this network using a modified version of Courtois' method. This work was extended to analyze tandem networks with a large number of wavelengths and resources per wavelength using a modified version of the recursion developed by Nilsson et. al. Finally, we extended our work to a traffic-groomed tandem optical network employing alternate routing and supporting traffic from multiple sources. For each method, numerical results show that, overall, our approximation provides good accuracy.

Book excerpt: Optical networks based on wavelength-division multiplexing (WDM) tech nology offer the promise to satisfy the bandwidth requirements of the Inter net infrastructure, and provide a scalable solution to support the bandwidth needs of future applications in the local and wide areas. In a waveleng- routed network, an optical channel, referred to as a lightpath, is set up between two network nodes for communication. Using WDM technology, an optical fiber link can support multiple non-overlapping wavelength channels, each of which can be operated at the data rate of 10 Gbps or 40 Gbps today. On the other hand, only a fraction of customers are expected to have a need for such a high bandwidth. Due to the large cost of the optical backbone infrastruc ture and enormous WDM channel capacity, connection requests with diverse low-speed bandwidth requirements need to be efficiently groomed onto hi- capacity wavelength channels. This book investigates the optimized design, provisioning, and performance analysis of traffic-groomable WDM networks, and proposes and evaluates new WDM network architectures. Organization of the Book Significant amount of research effort has been devoted to traffic grooming in SONET/WDM ring networks since the current telecom networks are mainly deployed in the form of ring topologies or interconnected rings. As the long-haul backbone networks are evolving to irregular mesh topologies, traffic grooming in optical WDM mesh networks becomes an extremely important and practical research topic for both industry and academia.

This book was released on 2006-01-19 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of fiber optic transmission systems and wavelength division multiplexing (WDM) have led to a dramatic increase in the usable bandwidth of single fiber systems. This book provides detailed coverage of survivability (dealing with the risk of losing large volumes of traffic data due to a failure of a node or a single fiber span) and traffic grooming (managing the increased complexity of smaller user requests over high capacity data pipes), both of which are key issues in modern optical networks. A framework is developed to deal with these problems in wide-area networks, where the topology used to service various high-bandwidth (but still small in relation to the capacity of the fiber) systems evolves toward making use of a general mesh. Effective solutions, exploiting complex optimization techniques, and heuristic methods are presented to keep network problems tractable. Newer networking technologies and efficient design methodologies are also described.

Available in PDF, EPUB and Kindle. Book excerpt: The convergence of multiservice heterogeneous networks and ever increasing Internet applications, like peer to peer networking and the increased number of users and services, demand a more efficient bandwidth allocation in optical networks. In this context, new architectures and protocols are needed in conjuction with cost effective quantitative methodologies in order to provide an insight into the performance aspects of the next and future generation Internets. This thesis reports an investigation, based on efficient simulation methodologies, in order to assess existing high performance algorithms and to propose new ones. The analysis of the traffic characteristics of an OC-192 link (9953.28 Mbps) is initially conducted, a requirement due to the discovery of self-similar long-range dependent properties in network traffic, and the suitability of the GE distribution for modelling interarrival times of bursty traffic in short time scales is presented. Consequently, using a heuristic approach, the self-similar properties of the GE/G/∞ are being presented, providing a method to generate self-similar traffic that takes into consideration burstiness in small time scales. A description of the state of the art in optical networking providing a deeper insight into the current technologies, protocols and architectures in the field, which creates the motivation for more research into the promising switching technique of 'Optical Burst Switching' (OBS). An investigation into the performance impact of various burst assembly strategies on an OBS edge node's mean buffer length is conducted. Realistic traffic characteristics are considered based on the analysis of the OC-192 backbone traffic traces. In addition the effect of burstiness in the small time scales on mean assembly time and burst size distribution is investigated. A new Dynamic OBS Offset Allocation Protocol is devised and favourable comparisons are carried out between the proposed OBS protocol and the Just Enough Time (JET) protocol, in terms of mean queue length, blocking and throughput. Finally the research focuses on simulation methodologies employed throughout the thesis using the Graphics Processing Unit (GPU) on a commercial NVidia GeForce 8800 GTX, which was initially designed for gaming computers. Parallel generators of Optical Bursts are implemented and simulated in 'Compute Unified Device Architecture' (CUDA) and compared with simulations run on general-purpose CPU proving the GPU to be a cost-effective platform which can significantly speed-up calculations in order to make simulations of more complex and demanding networks easier to develop.

Book excerpt: This book presents an in-depth treatment of routing and wavelength assignment for optical networks, and focuses specifically on quality-of-service and fault resiliency issues. It reports on novel approaches for the development of routing and wavelength assignment schemes for fault-resilient optical networks, which improve their performance in terms of signal quality, call blocking, congestion level and reliability, without a substantial increase in network setup cost. The book first presents a solution for reducing the effect of the wavelength continuity constraint during the routing and wavelength assignment phase. Further, it reports on an approach allowing the incorporation of a traffic grooming mechanism with routing and wavelength assignment to enhance the effective channel utilization of a given capacity optical network using fewer electrical-optical-electrical conversions. As a third step, it addresses a quality of service provision scheme for wavelength-division multiplexing (WDM)-based optical networks. Lastly, the book describes the inclusion of a tree-based fault resilience scheme in priority-based dispersion-reduced wavelength assignment schemes for the purpose of improving network reliability, while maintaining a better utilization of network resources. Mainly intended for graduate students and researchers, the book provides them with extensive information on both fundamental and advanced technologies for routing and wavelength assignment in optical networks. The topics covered will also be of interest to network planners and designers.

Book excerpt: This book contains the refereed proceedings of the 3rd International IFIP-TC6 Networking Conference, Networking 2004. Conferences in the Networking series span the interests of several distinct, but related, TC6 working groups, including Working Groups 6.2, 6.3, and 6.8. Re?ecting this, the conference was structured with three Special Tracks: (i) Networking Technologies, Services, and Protocols; (ii) Performance of Computer and Communication Networks; and (iii) Mobile and Wireless Communications. However, beyond providing a forum for the presentation of high-quality - search in various complementary aspects of networking, the conference was also targetedtocontributingtoauni?edviewofthe?eldandtofosteringtheinter- tion and exchange of fruitful ideas between the various related (and overlapping) specialized subcommunities therein. Towards this second objective, more than a few conference sessions (and thematic sections in this book) ‘cut across’ the Special Tracks, along more generic or fundamental concepts. Networking 2004 was fortunate to attract very high interest among the c- munity, and the conference received 539 submissions from 44 countries in all ?ve continents. These ?gures correspond to a remarkable increase in subm- sions from the previous very successful events (roughly, a 156% increase over Networking 2000 and 71% over Networking 2002), and indicate that Netw- king conferences are progressively becoming established as worldwide reference events in the ?eld.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Wavelength Division Multiplexing (WDM) is now being widely used in optical networks. WDM significantly increases the capacity of a single fiber by allowing it to simultaneously transmit multiple wavelengths. While such enormous capacity is very exciting, it has also led to the advent of drastically more complex WDM networks. In this work, we consider two architecture design problems for optical networks: (1) the optimal amplifier placement problem, and (2) the traffic grooming, routing, and protection problem for optical networks. In an optical network, optical signals from transmitters attenuate gradually as they propagate through optical fibers, therefore their strength needs to be restored by optical amplifiers before they become too weak to be detected by receivers. Optical amplifiers, however, also introduce the spontaneous emission noise, which is a major problem associated with them. In general, a long optical channel needs enough amplifiers in order to limit the cumulative spontaneous emission noise and attain adequate amplification gain. In our amplifier placement problem, the goal is to minimize the cost associated with optical amplifiers in an optical network subject to constraints on the cumulative spontaneous emission noise. The optical network can be a linear or a mesh network, and the locations of amplifiers can be arbitrary or pre-specified, which are referred as continuous and discrete case, respectively. We propose several different methods based on various optimization techniques and heuristics to solve the problem. In the second part of this work, we consider the traffic grooming, routing, and protection problem in optical networks. There are two basic architectures used in optical networks: ring and mesh. The ring architecture is relatively simple and easy to implement, and it also provides a straightforward way for traffic protection. On the other hand, the mesh architecture is more resilient to various network failures, but is much more complex. Recently, a hybrid architecture that is based on and takes advantage of both ring and mesh architectures has been proposed. We study the traffic grooming, routing, and protection problem for ring, mesh, and hybrid architectures, and use a two-step approach in conjunction with the linear programming technique to solve the problem. Numerical results are provided for a comprehensive comparison between these different architectures.
