Despite the current crisis of the telecom industry, our everyday life increasingly depends on communication networks for information exchange, medicine, education, data transfer, commerce, and many other endeavours.

High capacity links are required by the large futemet traffic demand, and optical networks remain one of the most promising technologies for meeting these needs. WDM systems are today widely deployed, thanks to low-cost at extreme data rates and high reliability of optical components, such as optical amplifiers and fixed/tunable filters and transceivers. Access and metropolitan area networks are increasingly based on optical technologies to overcome the electronic bottleneck at the network edge.

Traditional multi-layer architectures, such as the widely deployed IP/ATM/SDH protocol stack, are increasingly based on WDM transport; further efforts are sought to move at the optical layer more of the functionalities available today in higher protocol layers. New components and subsystems for very high speed optical networks offer new design opportunities to network operators and designers.

The trends towards dynamically configurable all-optical network infrastructures open up a wide range of new network engineering and design choices, which must face issues such as interoperability and unified control and management.

Since their commercial arrival in the nineties, they have fundamentally changed the way of dealing with traffic engineering by removing bandwidth bottlenecks and eliminating delays. Today, after the revolutionary bandwidth expansion, the networking functionality migrates more and more to the optical layer, and the need to establish fast wavelength circuits and capacity-on-demand for the higher-layer networks, in particular data networks based on Internet Protocol (IP), has become one of the central networking issues for the new century. The unifying trends toward configurable all-optical network infrastructure open up a wide range of new network engineering and design choices dealing with networks' interoperability and common platforms for control and management. The Fifth Working Conference on Optical Network Design and Modelling, held in the Austrian capital Vienna, February 5-7, 2001, aims at presenting the most recent progress in optical communication techniques, new technologies, standardisation process, emerging markets and carriers. A short look at the Table of Contents of this book tells us, in fact, that this year's conference program reflects the current state of the art precisely. Author by: Kemal Bengi Language: en Publisher by: Springer Science & Business Media Format Available: PDF, ePub, Mobi Total Read: 37 Total Download: 593 File Size: 44,7 Mb Description: The breathtaking success of the WDM technology in backbone networks also pushes the development and implementation of optical packet-switched WDM local and metropolitan area networks.

Local and metropolitan area optical WDM networks are emerging as viable and cost-effective solutions for many telecommunication operators and service providers who have to face an extremely growing bandwidth demand and expensive additional fiber installation costs. Thus, the strong need for the development of novel high-speed architectures and protocols for such networks arises. In Optical Packet Access Protocols for WDM Networks, different basic and novel medium access control (MAC) protocols for WDM-based LANs/MANs, typically belonging to the group of single-hop networks, are proposed and analyzed. Thereby, solutions for the direct and efficient support of distinct Quality-of-Service (QoS) classes over the WDM transmission layer are provided.

Besides a comprehensive overview on the state-of-the-art photonic metro networks, highly dynamic reservation-based access protocols relying on the passive-star and the ring topology are presented while assuming the deployment of wavelength-tunable transceivers at the network nodes. Optical Packet Access Protocols for WDM Networks provides both a comprehensive survey on existing WDM local and metro lightwave systems and the design of novel highly efficient medium access control protocols with QoS support for such systems. Accordingly, this work is appropriate for communication and network engineers from both the academic and industrial world working in the field of optical communication networks, computer science, and communication engineering.

Author by: Stephan Pachnicke Language: en Publisher by: Springer Science & Business Media Format Available: PDF, ePub, Mobi Total Read: 35 Total Download: 503 File Size: 44,5 Mb Description: Next generation optical communication systems will have to transport a significantly increased data volume at a reduced cost per transmitted bit.

To achieve these ambitious goals optimum design is crucial in combination with dynamic adaptation to actual traffic demands and improved energy efficiency. In the first part of the book the author elaborates on the design of optical transmission systems. Several methods for efficient numerical simulation are presented ranging from meta-model based optimization to parallelization techniques for solving the nonlinear Schrﾃｶdinger equation. Furthermore, fast analytical and semi-analytical models are described to estimate the various degradation effects occurring on the transmission line. In the second part of the book operational aspects of optical networks are investigated.

Physical layer impairment-aware routing and regenerator placement are studied. Finally, it is analyzed how the energy efficiency of a multi-layer optical core network can be increased by dynamic adaptation to traffic patterns changing in the course of the day.

Author by: Ramesh Bhandari Language: en Publisher by: Springer Science & Business Media Format Available: PDF, ePub, Mobi Total Read: 37 Total Download: 361 File Size: 42,8 Mb Description: Survivable Networks: Algorithms for Diverse Routing provides algorithms for diverse routing to enhance the survivability of a network. It considers the common mesh-type network and describes in detail the construction of physically disjoint paths algorithms for diverse routing. The algorithms are developed in a systematic manner, starting with shortest path algorithms appropriate for disjoint paths construction. Key features of the algorithms are optimality and simplicity. Although the algorithms have been developed for survivability of communication networks, they are in a generic form, and thus applicable in other scientific and technical disciplines to problems that can be modeled as a network.

A notable highlight of this book is the consideration of real-life telecommunication networks in detail. Such networks are described not only by nodes and links, but also by the actual physical elements, called span nodes and spans. The sharing of spans (the actual physical links) by the network (logical) links complicates the network, requiring new algorithms.
