Deflection Routing in OBS Networks

Abstract

Optical Burst Switching (OBS) network proposed as future optical internet is capable of carrying bursty traffic and adapting to the present technological constraints. Since the OBS network is buffer-less in nature, contention resolution using deflection technique received much attention. Deflection routing can work with limited optical buffering or even no buffering. This paper gives an overview of the research done so far in this area of deflection routing in OBS networks.
