摘　　要：在研究链路管理协议(LMP)单域故障定位的基础上,提出了一种自动交换光网络(ASON)的域间节点故障定位的新型方法。基于网关节点跨域通信的域间节点故障定位机制,利用ASON分布式控制平面完成故障定位功能,可以不依赖于传送平面的编码方式和网管人员的参与,并在各种域间节点故障情形下分别阐述了定位机制的工作原理以及定位过程。On the basis of research on fault localization in single-domain using link management protocol （LMP）, a novel method to locate inter-domain node failure in automatic switched optical network（ASON） is proposed based on the communications between inter-donmain nodes. The proposed method accomplishes the inter-domain fault localization by using distributed control plane in ASON,thus it is not dependent on transport plane s encoding manners and network manager s experience. Further the principle of our proposed method and the process of fault localization are set forth under different circumstances of inter-domain node failure.
