Abstract

A new scheme for optical burst switching (OBS) networks under self-similar traffic is proposed in this paper. Self-similar traffic is classified into two types of payload by partial pre-deflection edge node router, and the two types of payload are transferred using different routing algorithms - least hop first routing and shortest path first routing respectively, in order to properly utilize network resources and avoid burst contention at the core node switch. Simulation results indicate that the new scheme performs better than fixed routing and alternative routing for OBS networks under self-similar traffic. Furthermore, the implement of this scheme is feasible and easy, which makes OBS technology more applicable in network engineering (NE).
