In Optical Burst Switching (OBS) networks, issues related to burst losses are of major concern. Burst contention recovery techniques are needed in the OBS layer in order to reduce random burst-contention losses, thereby improving the transmission reliability of OBS networks. The existing works rarely consider the burst loss and loss of recovery packets which may lead to contention, burst failures and shrinking of congestion window. In this paper, the authors propose to design a simultaneous multi-path transmission along with path interleaving. Initially, in the FEC coding technique, the data blocks containing redundant bursts are gathered together and the redundant bursts are separated. When burst loss occurs continuously, the FEC encoding technique is combined with path interleaving which can be used to recover the continuous lost bursts.
