In Optical Burst Switching networks there is a need for the promising solution to minimize the burst loss. When a burst enters into the ingress node of the network and finds the server free, burst transmission takes place normally. If the server is busy, the burst would enter into the buffer at the ingress node and the burst retransmission takes place after sometime or the burst leaves the network as impatient burst. This reduces number of bursts being processed in the network. To avoid burst loss, buffering and retransmission techniques are combined. The effect due to the presence of positive bursts and negative bursts and the effect of pre emptive priority on the number of bursts being processed in the network are analyzed.
