Abstract

In OBS networks, Burst Header Packet (BHP) contentions occur when two or more BHPs are switched simultaneously to the same output port at a given core node. Such contention events result in significant losses of the corresponding data burst. Accordingly, the present study proposes a Store-and-forward COntention-REsolution mechanism, designated as SCORE, based on fiber delay line buffers to resolve the BHP collision problem in OBS networks, thereby minimizing the associated burst loss rate. A series simulation results performed using an OIRC OBS-ns simulator confirm the effectiveness and efficiency of the proposed scheme.
