Embodiments of the present invention provide a packet forwarding method and a network device, which are applicable to a system that includes a source node, a destination node, a first device, and a second device, where a first logical channel L1 is established between the source node and the first device and a second logical channel L2 is established between the source node and the second device, a third logical channel L3 is established between the destination node and the first device and a fourth logical channel L4 is established between the destination device and the second device, and the packet forwarding method includes: receiving, by the second device through a universal tunnel, a packet to be sent to a destination node, where the packet carries service data and one of identifiers of the L1, the L2, the L3, and the L4; according to the identifier carried in the packet, querying a preconfigured logical channel mapping in the second device, determining that a forwarding channel is the L4, and sending the service data in the packet to the destination node through the L4, where the logical channel mapping is a mapping between a logical channel and the L4, and the logical channel corresponds to the identifier. By using the technical solutions, the number of ICB PWs can be reduced. |
