Design of Three Priority Control Protocol Applied to Plastic Optic Fiber Access Network
用于塑料光纤接入网的三优先级控制协议设计

A novel multi-priority reservation protocol for plastic optical fiber access network based on OCDMA technology was proposed.Using reservation scheme and distributed arbitration algorithm,channel collision and destination conflict can be avoided.The network throughput and average delay were investigated by numerical analysis and simulation experiments through discrete time Markov model.Transmit channels are distributed according to the different delay demands of all kinds of services by using priority control protocol.The network throughout and system delay are calculated and simulated.The delay-time decreased as the number of the channel increases.The throughout stabilized while the delay-time increased with the increasing of load.It is shown that the multi-priority reservation protocol in POF access network based on OCDMA technology can efficiently support the transmission of multimedia messages that require the different time-delay.
