Executive Summary

In this paper a novel contention resolution technique based on control packet buffering in OBS networks is proposed. This buffering is implemented in the electronic domain, thus avoiding complex optical domain solutions. The aim of this paper is to add a new feature, namely the control packet buffering, to the MAC layer of the OBS network as a new contention resolution technique. This feature represents a new modification to the Just In Time (JIT) one way reservation protocol and does not depend on the medium access technique. Therefore, it can be implemented, for example above a WDM or OCDMA layer, to enhance the overall performance of the system.
