Paper Abstract

To support efficiently the ever growing burst traffic on the Internet (web traffic, broadband multimedia services) over all-optical WDM networks, optical burst switching (OBS) has been proposed as a promising switching method to exploit terabit capacity of optical networks. Fault- tolerant routing for OBS networks has not been studied in the literature. In this paper, we present a distributed scheme of fault- tolerant routing using detours for OBS Networks. Offset time between control packet and subsequent data bursts is varied to accommodate detours. The performance of the routing scheme is evaluated, through simulation, in terms of the burst loss probability for different network parameters like a number of wavelengths and the traffic load. We show that by tuning the offset time, the routing can very efficiently achieve low burst loss probability.
