Abstract: Optical burst switching (OBS) is developed as an alternative switching technology, which combines advantages of both optical circuit switching (OCS) and optical packet switching (OPS) and avoids the disadvantages. In OBS control packet called control burst is separated from data packet called data burst. A control burst is sent in advance, which configures the switches in the path for the data burst. Due to lack of adequate contention resolution technique data burst loss is high in OBS. Schemes such as fiber delay line (FDL), wavelength conversion, deflection routing are the solution to prevent network congestion. But they have their own limitations. So a contention resolution technique is needed in OBS. In this paper we propose a scheme to minimize contention and to control traffic flow in the network. The proposed scheme logically divides a given network to clusters and selects a node as cluster head from each cluster. Cluster head keeps track of the resources available in the networ...
