    • A communication network management system has: a communication network including a plurality of nodes and a plurality of links connecting between the plurality of nodes; and a management computer that manages the communication network. The management computer has: a storage means in which a route information indicating a transfer route of frames in the communication network is stored; and a monitoring means configured to perform, based on the route information, transmission and reception of frames to and from the communication network. The monitoring means transmits a frame to the transfer route. Each of the plurality of nodes, when receiving a frame, not only forwards the received frame along the transfer route but also sends a reply to the management computer. The monitoring means identifies a location of failure occurrence on the transfer route, based on reception state of the reply from the plurality of nodes.
    • 通信网络管理系统具有:包括多个节点的通信网络和在所述多个节点之间连接的多个链路; 以及管理通信网络的管理计算机。 管理计算机具有:存储装置,其中存储指示通信网络中的帧的传送路由的路由信息​​; 以及监视装置,被配置为基于所述路由信息来执行到所述通信网络和从所述通信网络的帧的发送和接收。 监视装置将帧传送到传送路由。 多个节点中的每一个在接收帧时不仅沿着传送路由转发接收到的帧,而且还向管理计算机发送回复。 监视装置基于来自多个节点的回复的接收状态来识别传送路由上的故障发生的位置。
