Load balanced multipath deflection Routing and scheduling with burst Loss recovery in optical burst Switching networks

Abstract

The telecommunications industry has faced extraordinary challenges newlineduring the past twenty five years and with the applications requiring large newlinebandwidth includes Voice over IP VoIP Video on Demand VoD services newlineand Grid computing The state of the art telecommunication networks must be newlineable to provide huge and increasing capacities without additional bandwidth newlineOptical Burst Switching OBS has sky high prospects as a newlineswitching technique that can support the high bit rate transport service with newlinebandwidth efficient under dynamic Internet traffic loads Data and control newlineinformation are sent through different wavelength channels in an OBS newlinesystem The user data is transmitted in variable size data packets, called burst newlinewhich is an optical signal along its path The control packet for each burst is newlinetransmitted prior to its corresponding burst and it is electronically processed newlineat each hop along the path of the upper layer traffic newlineThe loss of a single burst may create severe issues for the upper newlinelayer connection establishments Hence the performance of an OBS network newlineis normally determined based on the burst loss probability However the burst newlineloss performance is highly affected by burst contention in the network newline newline
