Method for acquiring target transmission path and network node

摘要

Embodiments of the present invention relate to a method for obtaining a target transmission path and a network node. In the method, the first network node in the network area obtains topology information of a plurality of network nodes on each path between the ingress node and the egress node in the network area, and the first network node Obtain the transmission delay of each path according to the information, and the transmission delay of each path is the sum of the physical link delay between all network nodes on each path and the node residence time of all network nodes on each path. Including a first network node determining a target transmission path according to a transmission delay of each path. In a method and network node for obtaining a target transmission path in an embodiment of the present invention, a transmission of a low-latency service in a network satisfies a delay request, and a plurality of low-latency paths between an ingress node and an egress node in the network are completely It can be ensured that it can be used, thereby improving the transmission reliability of low-latency services.
