A new scheme to provide Reliable transmission in optical burst switch networks

A key challenge faced by optical burst switch networks(OBS) is how to resolve burst contention that happens when two or more incoming bursts contending for the same output line (the same wavelength) at an optical switch. Most of the research effort has been devoted to reduce the burst loss probability due to contention, which cannot eliminate the loss completely. We propose an algorithm named as RCO (redundant coding optical) to provide reliable burst transmission in OBS networks. The simulation result confirms the correctness and performance of our algorithm.
