摘　　要：随着APON在接入网市场占有率的不断上升,人们对APON接入网的可靠性和灵活性也提出了更高的要求。基于此,在简单比较了现有的几种APON自愈保护机制的基础上,根据ITU-T G983.5建议,探讨了一种类似于SDH自愈环的高可靠性APON网络拓扑结构,详细分析了其APS协议操作过程及实现方案,最后给出了这种方案的性能评价。With the continuous increase of market share of APON system in local access network field, higher survivability and flexibility of APON system are required . This paper begins with a survey of exited APON self-healing architecture .Then based on ITU-T recommendation G983.5 this paper discusses a high survivability APON topology similar to a SDH self-healing ring , analyzes the implementation of APS protocal and its realization. Finally, the performance analysis of this scheme is given.
