Abstract
A forwarding entry generation method includes sending, by a controller, a plurality of resource allocation request messages to a plurality of network devices in a network slice, to trigger the plurality of network devices to allocate resources, where the resource allocation request message includes an identifier of the network slice and a resource that needs to be allocated by a corresponding network device to the network slice; receiving, by the controller, a plurality of resource allocation response messages including the identifier of the network slice and a segment identifier of a corresponding network device, and a resource allocated by each device belongs to the network slice; and generating, by the controller, a forwarding table corresponding to the network slice, where the forwarding table includes a forwarding entry for arriving at a network device in the network slice.
