Performance Analysis of Optical Burst Switching (OBS) Network

Optical Burst Switching (OBS) is a promising switching paradigm for all-optical WDM networks. It combines advantages of both Optical circuit switching (OCS) and Optical packet switching (OPS) and avoids the disadvantages. Optical Burst Switching (OBS) is a new paradigm where the use of modeling and simulation tools is very important. In OBS there is strong separation between control packet called control burst and 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. In this paper we present a complex topology. NS-2 is used as simulation software in this parametric study. The result shows the significant reduction in the BLR
