We propose a simple and scalable scheduler called Elapsing Time-based Priority (ETP) scheduler for the optical burst switch (OBS) control channel; it eliminates the requirements of global synchronization and core-state information. This scheduler reduces edge-to-edge delays of burst control packets and total latencies of data bursts.
