Available in PDF, EPUB and Kindle. Book excerpt: Many applications and telecommunications services in futurehigh-speed networks will require some form of multipointcommunication. The problems associated with providing network support formultipoint communication have been widely studied within anumber of different networking contexts. As current network technologies evolve to an all-optical, largely passive infrastructure, these problems takeon new significance and raise a number of challenging issuesthat require novel solutions. We consider the problem of supporting multipoint communication at the media access control (MAC) layer of broadcast-and-select Wavelength Division Multiplexed (WDM) networks. In this environment, bandwidth consumption and channel utilization arise as two conflicting objectives in the design of scheduling algorithms for multicast traffic. We present a new technique for the transmission of multicast packets which is based on the concept of a virtual receiver. This is a set of physical receivers which behave identically in terms of tuning. We focus on the problem of optimally selecting the virtual receivers, and prove that it is NP-complete. We then present four heuristics of varying degrees of complexity for obtaining virtual receivers that provide a good balance between the two conflicting objectives. The dynamic nature of multicast traffic could affect the balance obtained with the virtual receivers when the network conditions change. We study the sensitivity to changes of the virtual receiver sets and the cost associated with handling the changes. Also, the cost of three different approaches to handling the changes is analyzed. Finally, we study the performance of various strategies for scheduling a combined load of unicast and multicast traffic in a broadcast WDM network. Three different scheduling strategies are presented, namely: separate scheduling of unicast and multicast traffic, treating multicast traffic as a number of unicast messages, and treating unicast traffic as multicasts of size on.

Available in PDF, EPUB and Kindle. Book excerpt: Research and development on optical wavelength-division multiplexing (WDM) networks have matured considerably. While optics and electronics should be used appropriately for transmission and switching hardware, note that "intelligence'' in any network comes from "software,'' for network control, management, signaling, traffic engineering, network planning, etc.The role of software in creating powerful network architectures for optical WDM networks is emphasized. Optical WDM Networks is a textbook for graduate level courses. Its focus is on the networking aspects of optical networking, but it also includes coverage of physical layers in optical networks. The author introduces WDM and its enabling technologies and discusses WDM local, access, metro, and long-haul network architectures. Each chapter is self-contained, has problems at the end of each chapter, and the material is organized for self study as well as classroom use. The material is the most recent and timely in capturing the state-of-the-art in the fast-moving field of optical WDM networking.

This book was released on 2016-01-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: To meet the recently increasing traffic demand, WDM techniques have been evolving to efficiently exploit the huge capacities of all-optical networks. This book focuses on constrained all-optical multicast routing (AOMR) in WDM networks. Conventional consensus to model optical multicast routes based on trees is no longer adequate. Therefore the study relies on a more general graph-related structure called hierarchy. The book begins by introducing fundamental WDM technological backgrounds, mathematical modeling to the problems and literature review in the three first chapters. The detailed investigations for specific network scenarios are presented in the next three chapters, including ILP formulations, techniques to prove NP-hardness, and heuristic algorithms. Simulation results show that the optimal solutions for constrained AOMR problems correspond to hierarchies which can model not only the existing solutions as light-trees, but also the novel light-structures as light-hierarchies. Those who are interested in optical WDM networks, graph theory, complexity theory, combinatorial optimization, or heuristic algorithms can find this book a very interesting and helpful reference.

Available in PDF, EPUB and Kindle. Book excerpt: There is a growing number of services over the Internet which are best supported by multicasting transmission, defined as one source node of information delivering it to a number of destinations. Optical networking is a promising technology for supporting the expected large volume of multicast traffic, due to its native ability to offer high transmission rates, e.g., 10, 40, 100 Gbps. Optical technology is also well suited for circuit oriented services. Circuits can be created by either reserving an entire wavelength (color) in Wavelength Division Multiplexing (WDM) network, or by reserving just a sub-carrier of a wavelength. In the dissertation, we refer to this assigned wavelength or sub-wavelength as a color which has to be assigned to the circuit. The main contribution of this dissertation is the introduction of a metric (contention degree) solution that is enabling the routing algorithm (or protocol) to account for the problem of assigning a color to the circuit. The objective of the routing algorithm is to compute the multicast tree for the multicast request to span across the network.

Download or read book Optical Multicasting in Multi-Line-Rate Ethernet-over-WDM Backbone Networks written by Shruthi Harve and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ethernet is the dominant technology for local-area networks (LANs) due to its simplicity, flexibility, and cost efficiency. In order to carry Ethernet traffic over backbone networks of metropolitan-area networks (MANs) and wide-area networks (WANs), the current mode of operation requires the conversion of Ethernet signals to technologies used by the backbone networks using complex and expensive equipment. In order to avoid this sort of unnecessary conversion, efforts are now under way to extend the usage of Ethernet from LANs to carrier-grade Ethernet in backbone networks of different service providers, and to provide a unified platform for transporting traffic. With the advent of muticast applications such as Internet Protocol TV (IPTV) and Video-on-Demand, there is a need for techniques to efficiently route multicast traffic over Ethernet backbone networks. Here, we address the problem of Routing and Wavelength Assignment (RWA) of a set of multicast requests in a Multi-Line-Rate (MLR) Ethernet backbone network with the objective of minimizing the cost of setting up the network, in terms of the Service Provider's Capital Expenditure (CAPEX). We present an Auxiliary Graph-based heuristic algorithm that routes each multicast request on a light-tree structure, and assigns minimum-cost wavelengths along the route. The algorithm utilizes the flexibility extended by MLR wavelength-division-multiplexed (WDM) optical networks used to construct the Ethernet backbone, by re-using channels, and using appropriate weight-assignment schemes to make a cost-efficient choice of wavelengths. We compare the properties of the algorithm to the optimal solution given by a mathematical model formulated as an Integer Linear Program (ILP), and show that they compare very well for small networks. The algorithm is tested on bigger networks, and it is shown that the algorithm is most cost-effective when the incoming traffic requests are processed in descending order of their bandwidth requirements, while using the linear weight-assignment scheme with volume discount.

Book excerpt: With the rapid growth of bandwidth demand from network users and the advances in optical technologies, optical networks with multiterabits per-second capacity has received significant interest from both researchers and practitioners. Optical networks deployment raises a number of challenging problems that require innovative solutions, including net work architectures, scalable and fast network management, resource efficient routing and wavelength assignment algorithms, QoS support and scheduling algorithms, and switch and router architectures. In this book, we put together some important developments in this exiting area during last several years. Some of the articles are research papers and some are surveys. All articles were reviewed by two reviewers. The paper, "On Dynamic Wavelength Assignment in WDM Optical Networks," by Alanyali gives an overview of some issues in the analy sis and synthesis of dynamic wavelength assignment policies for optical WDM networks and illustrates a new method of analysis. The paper by Ellinas and Bala, "Wavelength Assignment Algorithms for WDM Ring Architectures," presents two optimal wavelength assignment algorithms that assign the minimum number of wavelengths between nodes on WDM rings to achieve full mesh connectivity.
