APON中MAC协议的研究现状

The Current Development of MAC Protocol in APON

以高度概括来观察MAC协议,分别从APON承载的业务、带宽分配的对象、承载请求信息的通道和动态带宽分配算法等几个方面介绍了当前MAC协议研究的进展。最后,提出了一个有待研究的新问题。

MAC protocol is a key technology in APON system, so this paper makes great efforts to investigate it from a general viewpoint. The current development of MAC protocol is presented from several aspects, such as carried services, the object of bandwidth allocation, the channel of requests and dynamic bandwidth assignment. Furthermore, a new problem is introduced at the end of this paper expecting more study.
