    • Provided is a method of monitoring link performance and diagnosing an active link state without interrupting traffic in an Ethernet passive optical network (EPON) while the link is in the active state. The method of monitoring link performance and diagnosing an active link state without interrupting data flow to logic links which are in active states in the EPON, includes: a) allowing an operator of the EPON to select a link performance monitoring function or a link active state diagnosing function; b-1) if the link performance monitoring function is selected, setting a monitoring cycle timer and periodically transmitting a performance information request frame from a local node to a remote node; b-2) if the remote node receives the performance information request frame, collecting corresponding link performance information and transmitting a response frame from the remote node to the local node in a format which is predetermined in accordance with a corresponding frame format; b-3) if the local node receives the response frame from the remote node, analyzing the performance information of the response frame and determining whether the link performance has deteriorated or if a failure has occurred in the local node; b-4) if the deterioration of the link function or the degree of the failure reaches a predetermined threshold, reporting to an upper layer that a failure has occurred.
    • 提供了一种在链路处于活动状态时监视链路性能和诊断活动链路状态而不中断以太网无源光网络(EPON)中的业务的方法。 监视链路性能和诊断活动链路状态而不中断到EPON中处于活动状态的逻辑链路的数据流的方法包括:a)允许EPON的运营商选择链路性能监视功能或链路活动状态 诊断功能; b-1)如果选择了链路性能监视功能,则设置监视周期定时器并且周期地从本地节点向远程节点发送性能信息请求帧; b-2)如果所述远程节点接收到所述性能信息请求帧,则收集对应的链路性能信息,并以根据对应的帧格式预定的格式从所述远程节点向所述本地节点发送响应帧; b-3)如果本地节点从远程节点接收到响应帧,分析响应帧的性能信息,确定链路性能是否恶化,或者本地节点是否发生故障; b-4)如果链路功能的劣化或故障程度达到预定阈值,则向上层报告发生故障。
