Contention resolution is one of the critical technologies in optical burst switch network, In this paper, we focused on this challenging issue, and introduce a novel scheme called batch channel-schedule. In a conventional OBS network, core node will process BHP(burst head packet)at once when it arrives, yet in our batch schedule mode, BHP is queued and then processed combining with a certain schedule algorithm at a batch schedule time. In this way, a much better decision can be made about a lot of bursts all-together. Through simulations, our algorithm is proved to improve performance and reduce burst loss probability.
