Feasibility Study of Optical Packet Switching Network
Optical technology supplies capabilities necessary to create an optical packet switching network providing large bandwidth, high-speed data transmission and service differentiation. The aim of this thesis work is a logical performance analysis of optical packet-switching network.Studied network is based on the synchronous optical packet switching. Main part of this work deals with the analysis of two architectures: interior switch and access node. Two interior node architectures are proposed: a memory less switch and switch incorporating memory buffers based on the fiber delay lines. The access node is studied with focus on its ingress functions. Two algorithms of optical packet creation are considered: assembly and segmentation.Performance of proposed nodes is evaluated using simulation tool and discrete-time Markov chain. We show that optical packet switching network performs very well under different conditions and it is one of the promising solutions for the future high-speed networks.

Optical Switching/Networking and Computing for Multimedia Systems
This volume reveals the latest research on commercial systems with up to 160 OC-48 channels, optical ATM switch architectures, optical multiprotocol lambda and label switching, synchronous optical networks and digital hierarchy, and the Internet Protocol layer. The text includes recent developments in the routing efficiency of multihop optical networks supported by wavelength division multiplexing (WDM) with limited wavelength conversion. It also explores different routing techniques in WDM networks for virtual topology mapping, wavelength routing and assignment, dynamic routing, QoS provisions, and multicasting. The book examines challenges facing carriers and service providers in expanding optical networking capabilities for the next generation Internet.
