Modeling the High Performance Transmission Control Protocol for Supporting IP Packet over WDM Ring Networks

In this paper, a carrier preemption access control protocol based on carrier sense multiple access schemes has been investigated for supporting IP packets over all optical WDM ring networks. The intention of our protocol design is to reduce the communication overhead of IP packets over optical networks for local/metropolitan area. To facilitate spatial reuse on the bandwidth of all optical ring networks, a special design is made for the carrier preemption scheme. An approximate analysis, base on the M/G/l queuing model, has been developed to evaluate the performance of our protocol. The analytical results show an excellent agreement with simulation results over a broad range of parameters. The results show that the proposed protocol can achieve higher bandwidth efficiency and lower access delay.
