Abstract

Optical Burst Switching (OBS) has been proposed as a cost-effective paradigm for supporting, with adequate flexibility, the increasingly high transmission capacity required by the forthcoming next generation of optical internet networks. However, OBS efficiency can be reduced by resource contention of bursts directed to the same transmission links, leading to burst loss. This paper presents a discrete event simulation model and its implementation using OMNeT++ aimed at the evaluation of different routing strategies in terms of link contention. The simulation model is used to compare the performance of novel path selection strategies proposed in [1] with the traditional routing strategy that uses the shortest path. The simulation results confirm that the proposed path selection strategies are effective in reducing the overall network burst drop probability.
