Available in PDF, EPUB and Kindle. Book excerpt: Optical burst switching (OBS) is the most promising all-optical architectures for the next generation Internet. OBS is still being developed and several issues still need to be addressed. Several studies have stressed the importance of the choice of the offset time and its criticality in influencing the burst loss phenomenon in OBS networks. The main problem arises in estimating the initial delay that is compatible with the optical burst switching architecture implemented. This thesis aims to provide a mechanism to calculate the offset time and to study its effect on the network performance and refining QoS levels. The study is extended to networks under failure to investigate the influence of the delay factor on the restoration process especially in compensating failed-network performance degradations. The simulation studies validated the proposed mechanism and formed an annex that can be integrated on any OBS restoration mechanism. A new QoS parameter is defined to meet service differentiation with respect to the data losses and delays.

Available in PDF, EPUB and Kindle. Book excerpt: Optical Networks - Architecture and Survivability, is a state-of-the-art work on survivable and cost-effective design of control and management for networks with IP directly over Wavelength Division Multiplexing (WDM) technology (or called Optical Internet). The authors address issues of signaling mechanisms, resource reservation, and survivable routing and wavelength assignment. Special emphasis has been given to the design of meshed, middle-sized, and wavelength-routed networks with dynamic traffic in the optical domain, such as the next-generation Metropolitan Area Network. Research and development engineers, graduate students studying wavelength-routed WDM networks, and senior undergraduate students with a background in algorithms and networking will find this book interesting and useful. This work may also be used as supplemental readings for graduate courses on internetworking, routing, survivability, and network planning algorithms.
Download or read book Optical Burst Switched Networks written by Jason P. Jue and published by Springer Science & Business Media. This book was released on 2006-06-07 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Next-generation high-speed Internet backbone networks will be required to support a broad range of emerging applications which may not only require significant bandwidth, but may also have strict quality of service (QoS) requirements. Furthermore, the traffic from such applications are expected to be highly bursty in nature. For such traffic, the allocation of static fixed-bandwidth circuits may lead to the over-provisioning of bandwidth resources in order to meet QoS requirements. Optical burst switching (OBS) is a promising new technique which attempts to address the problem of efficiently allocating resources for bursty traffic. In OBS, incoming data is assembled into bursts at the edges of the network, and when the burst is ready to be sent, resources in the network are reserved only for the duration of the burst. The reservation of resources is typically made by an out-of-band one-way control message which precedes the burst by some offset time. By reserving resources only for the duration of the burst, a greater degree of utilization may be achieved in the network. This book provides an overview of optical burst switching. Design and research issues involved in the development of OBS networks are discussed, and approaches to providing QoS in OBS networks are presented. Topics include: - Optical burst switching node and network architectures - Burst assembly - Signaling protocols - Contention resolution - Burst scheduling - Quality of service in OBS networks
Download or read book Survivability and Traffic Grooming in WDM Optical Networks written by Arun Somani and published by Cambridge University Press. 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.

Book excerpt: WDM optical networks make it possible for the bandwidth of transport networks to reach a level on which any failures would cause tremendous data loss and affect a lot of users. Thus, survivability issues of WDM optical networks have attracted a lot of research work. Within the scope of this dissertation, two categories of problems are studied, one is survivable mapping from IP topology to WDM topology, the other is p-cycle protection schemes in WDM networks.

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.

Available in PDF, EPUB and Kindle. Book excerpt: COST – the acronym for European COoperation in Science and Technology – is the oldest and widest European intergovernmental network for cooperation in - search. Established by the Ministerial Conference in November 1971, COST is presently used by the scientific communities of 35 European countries to coop- ate in common research projects supported by national funds. The funds provided by COST – less than 1% of the total value of the projects – support the COST cooperation networks (COST Actions) through which, with € 30 million per year, more than 30,000 European scientists are involved in - search having a total value which exceeds € 2 billion per year. This is the financial worth of the European added value which COST achieves. A “bottom up approach” (the initiative of launching a COST Action comes from the European scientists themselves), “à la carte participation” (only countries interested in the Action participate), “equality of access” (participation is open also to the scientific communities of countries not belonging to the European - ion) and “flexible structure” (easy implementation and light management of the research initiatives) are the main characteristics of COST.
