中文摘要：

在以太网无源光网络帧结构的基础上,针对正交频分复用无源光网络的特点,提出了一种适用于正交频分复用无源光网络的媒质接入控制协议.对多点控制协议、控制消息的结构、业务优先级等进行了设计,提出了一种提供服务质量保障的特殊情况下区别用户服务等级的动态带宽分配算法.该算法引入两级调度的机制,将带宽资源的分配分为不同优先级业务的调度和同类型业务下不同等级的光网络单元调度.文章对提出协议的时延、丢包率、吞吐量等方面的性能进行了仿真,仿真结果显示提出的媒质接入控制协议很好地实现了对各业务的服务质量保障,符合多业务接入对服务质量等的需求.

英文摘要：

A novel media access control protocol is proposed based on EPON considering of the character of orthogonal frequency-division multiplexing passive optical network. Multi point control protocol,control message format and the priority of services are designed and a dynamic bandwidth allocation algorithms is proposed, which supports multi-service access and ensures quality of service distinguishing user level in specified case. The proposed algorithm uses two- level mechanisms and the allocating progress can be divided into two steps-schedule for different priority of services and schedule for different level optical network unit. The proposed protocol is simulated and the results of delay, packet loss ratio and throughput performance show that the proposed protocol guarantees the quality of service requirements for different services excellently, and meets quality of service requirements of multi-service access.
