Performance analysis of a centralized resource allocation mechanism for time-slotted OBS networks

Abstract

Time-Slotted Optical Burst Switching (TS-OBS) is one of the most promising next-generation transport network technologies. This paper proposes a time-slot assignment procedure using centralized control for TS-OBS networks. Our scheme attempts to improve burst contention resolution and optical channel utilization. Analysis and simulation results show that the channel utilization of the TS-OBS network is improved markedly at the expense of ingress buffering delay.
