METHOD, RELEVANT DEVICE AND SYSTEM FOR ACQUIRING A TARGET TRANSMISSION PATH

摘要

Provided are a method, relevant device and system for acquiring a target transmission path. The method is applied in flexible Ethernet (FlexE) networking, and the method comprises: receiving a first message, sent by a second node, for requesting to query a transmission path of a first FlexE client; and sending a second message to the second node, wherein a path information table entry in the second message comprises path information of the FlexE client on each node. By means of recoding ingress information and egress information of the FlexE client on path nodes and taking same as a transmission path of each hop, the transmission path of the FlexE network from segment to segment may be dynamically found in real time, a transmission path planned for deployment may be compared with an actually found path so as to evaluate the operation condition of the network, the connectivity on the transmission path may further be detected, and failure nodes on the transmission path in the FlexE network may be further positioned.
