Pre-planned Optical Burst Switching routing strategies

Abstract

This paper addresses the problem of pre-planned optical burst switching (OBS) routing strategies. Pre-planned OBS routing strategies can be applied as static routes in normal network operation without the need for resource-update signalling messages, combined with dynamic contention resolution schemes, or when the network tries to recover from a congestion state. In this paper, we discuss the applicability and performance improvement, when compared with shortest path routing, of two path selection strategies, taking into account different network topologies and strategy parameters.
