Abstract :
WDM single-hop networks allow a pair of nodes to exchange data packets directly and require an efficient protocol that coordinates the process of data transmission. However, the network performance with such protocols can be deteriorated by collisions that occur on the control channel, data channel, destination node and source node. We present a Collision-Free Reservation Protocol (CFRP) for WDM single-hop networks with a passive optical star coupler. To eliminate all causes of collision, the CFRP properly distributes the transmission schedule both in time (position of data channel on the time axis) and space (wavelength of data channel to be used). Compared with previous reservation-based protocols, the proposed CFRP enhances the overall network performance. This improvement in terms of network throughput and delay is verified through numerical implementations
