Abstract: Provided is a method for forwarding service data, a network device, and a network system. The forwarding method may include the following operation. A forwarding path for service data is determined according to network resource configuration information of a designated network and a network slice of the service data, wherein the network resource configuration information indicates one or more network slices associated with one or more network resources of the designated network, and a network slice associated with a network resource of the determined forwarding path matches the network slice of the service data; and the service data is forwarded according to the forwarding path.

Abstract: The present invention provides a packet forwarding method and device. The method comprises: a first node receiving a packet for forwarding, wherein a destination address of the packet is a second node; the first node identifying, from topologies generated in advance, a target topology corresponding to the packet, wherein the topologies generated in advance comprise a first topology and a second topology generated according to an MRT algorithm, and a third topology obtained according to an SPF algorithm, wherein the first topology, the second topology and the third topology are different from one another; and the first node identifying, from the target topology, a next hop node for forwarding to the second node, and forwarding the packet to the next hop node. The present invention achieves an object of combining a segmented routing network and an MRT function.
