고속 다중 파장망을 위한 효율적인 채널 예약 프로토콜 = An Efficient Channel Reservation Protocol for High Speed Multiwavelength Networks

다국어 초록 (Multilingual Abstract)

In the high speed multi-wavelength networks, signal propagation delay time is much larger than the transmission time of data packet. So retransmission overhead due to destination conflict or control packet collision is one factor of performance degradation.
An efficient WDMA protocol with a collision avoidance mechanism is proposed for high speed optical networks. It can be applied to the WDM single-hop network with a passive star topology. In proposed protocol, each node has source queues and routing table to store routing information. This architecture makes it possible to avoid any kind of collision when a node reserves the channel to transmit a data packet. High system thoughput and channel utilization can be achieved by proposed protocol since there are no discarded packets caused by any collision at transmission time. The performance of proposed is evaluated in terms of throughput and delay with variations in offered load. Simulation results show that the proposed protocol has superior performance to conventional protocols under nonuniform as well as uniform traffic.
