A method for acquiring a target transmission path and a method for acquiring a target node

摘要

An embodiment of the present invention relates to a method and network node for obtaining a target transmission path. The method includes: obtaining, by a first network node of a network domain, topology information of a plurality of network nodes on each path between an ingress node and an egress node in a network domain; The method comprising: obtaining, by a first network node, a transmission delay of each path in accordance with topology information, the transmission delay of each path comprising a physical link delay between all network nodes on each path and a node residence time - the sum of And determining, by the first network node, the target transmission path according to the transmission delay of each path. A method and a method for acquiring a target transmission path in an embodiment of the present invention are provided in which a transmission of a low delay service of a network satisfies a delay requirement and a plurality of low delay paths between an ingress node and an egress node of the network are fully utilized It can be ensured that the transmission reliability of the low-delay service is improved.
