In WDM passive star networks (PSN), Two critical problems that determine transmission performances are a data channel collision on transmission and a receiver collision at a receiver node. We propose a new transmission scheduling scheme that can efficiently avoid the above two collision problems and makes the class of service possible with high channel utilization. The proposed protocol introduces the self collision prediction mechanism with a fixed roundtrip delay by using the FDL at node registration state and adopts the multiple control slots for guaranteeing a low channel reservation time of the high class' real time traffic.
