摘　　要：随着EPON的部署规模逐渐增大,对EPON系统的测试越发显得重要。多点控制协议(MPCP)是EPON的核心控制协议,MPCP协议一致性验证对EPON设备互通测试和运行维护管理都是必要的。文章针对被动测试下MPCP协议一致性的验证方法展开研究。通过分析比较几种典型状态机模型,确定采用NFSM模型描述MPCP协议,设计并实现了MPCP协议一致性验证的算法。该算法已应用于参与研发的EPON被动测试仪中,能够完成对协议交互的正常过程及典型错误过程的识别。With gradually increasing scale of the deployment of EPON, the test solutions for EPON become more and more important. MPCP is the core control protocol for EPON protocol suite, The conformance test for MPCP implements is essential for EPON devices＇ interoperation and runtime management, The research in this thesis focus on the design and implement of MPCP conformance test, By analyzing several typical state machine model, we adopt NFSM model to describe the MPCP protocol, then design and implement the algorithm of MPCP conformance test. The algorithm have been applied in the prototype of EPON passive analyzer, and test activities on normal conversation and typical exceptions of MPCP protocol have been performed.
