Abstract

Optical Burst Switching (OBS) is supposed to be a promising switching technology in the future WDM networks, which is suitable to support burst traffic. A problem with OBS network is that bursts with longer routing lengths are more likely to be dropped before arriving at the destination router. In this paper, we propose two approaches using offset time differentiation (OTD) and burst length differentiation (BLD) to solve the burst loss differentiation (BLP) unfairness problem in OBS networks. Simulations show that BLP fairness in OBS is greatly enhanced with our approaches, especially with the OTD approach. Besides, we also investigate the BLP unfairness problem in offset time based QoS scheme.
