abstract = {Optical Burst Switching (OBS) aims to provide
higher utilization and greater flexibility at a lower cost and reduced
complexity than current optical circuit switched networks. We introduce a new
routing protocol for Optical Burst Switching, Shortest Path Prioritized Random
Deflection Routing (SP-PRDR), that aims to lower burst loss probabilities while
only using limited state information from traditional Internet Protocol
technologies. We show, through analysis and simulation, that loss in OBS
networks is significantly reduced by SP-PRDR for loads that previously gave
moderate or low losses in the unmodified case. In the simulation examples
studied, by using SP-PRDR we are able to increase the input load by
approximately 15-20% while maintaining a constant burst loss probability of
0.001. Additionally, unlike other schemes, we show that the worst case burst
loss probability of SP-PRDR is provably upper-bounded by the burst loss
probability of standard OBS.}
