1. A method for obtaining a target transmission path, applied to a network domain, comprising:
obtaining, by a first network node in the network domain, a physical link delay between an ingress node and an egress node;
obtaining a node residence time of each network node;
determining at least two target transmission paths between the ingress node and the egress node based on the physical link delay and the node residence times; and
transmitting a low-delay service packet on the at least two target transmission paths.
