In this paper, we evaluate the performance of a burst retransmission scheme in which the bursts lost due to contentions in an OBS network are retransmitted at the OBS layer. The retransmission scheme aims to reduce burst loss probability in OBS networks. We develop an analytical model for obtaining the burst loss probability over an OBS network that uses the retransmission scheme. We also compare the performance of the burst retransmission scheme with the deflection scheme. Simulation results also show that at a moderate traffic load, the retransmission scheme provides an improvement of up to four times the burst loss probability with the deflection scheme. Results also show that the retransmission scheme significantly improves the burst loss probability compared to an OBS network without the retransmission scheme.
