In future, the higher bandwidth can only be full-filled by utilizing the enormous bandwidth of the optical fiber. In OBS, packets are assembled into a burst, and a burst control packet is sent in advance to inform and reserve resources at the optical nodes in the path of the burst. OBS is a novel approach of aggregating multiple IP packets into a burst that is then trans-mitted without the need for any type of buffering at intermediate nodes. In this paper, we propose a contention resolution scheme that uses a offset time different from that of conventional optical burst switching (OBS) to reduce burst loss and to provide QoS in optical burst switching networks.
