Comparison of Various Scheduling Techniques in OBS Networks

Optical burst switching (OBS) is a viable approach proposed with the objective of utilizing the huge transmission capacity available with WDM links both efficiently and cost effectively. In this paper simulation results for an OBS node with self-similar traffic comparing with drop history schemes, CTBR with the Horizon and the LAUC-VF scheduling algorithms clearly indicate their overall scheduling performance aligned with burst drop checks and their burst length. CTBR is the fastest scheduling algorithm that can produce an efficient burst schedule than other scheduling techniques. The CTBR scheduler is entirely able to schedule both bursts successfully on the multiplexing link.
