Avoid Congestion Using Control Packet Buffering In Optical Burst-Switched Networks

Abstract - Optical Burst Switching OBS is a proposed new communication technology that seeks to expand the use of optical technology in switching systems. In this paper we propose a scheme to minimize the contention and to decrease a burst loss probability at OBS network. The key idea of the paper is that buffering is implemented in electronic domain. In addition we elaborate our proposed contention avoidance mechanism and system performance using burst loss probability steady state throughput load balancing and energy is presented. We also show through simulation that the proposed protocol is a viable solution for effectively reducing the conflict and increasing the bandwidth utilization for optical burst switching.
