Abstract: This application discloses a network slice information transmission method and apparatus. For example, a controller performs slice division on a network based on a service requirement and then obtains slice information, and sends the slice information to a first network device in the network by using a path computation element protocol (PCEP) packet, which includes first slice information corresponding to the first network device. After receiving the PCEP packet, the first network device parses the PCEP packet to obtain the first slice information, and further performs network slice configuration based on the first slice information. That is, in this application, the controller delivers the slice information by using the PCEP packet, so that after obtaining the PCEP packet, the first network device can obtain the first slice information corresponding to the first network device in a timely manner and perform network slice configuration without waiting for a configuration command.

Abstract: This application discloses a communication method and a related apparatus, and relates to the field of communication technologies. The method is applied to an SD-WAN overlay network. A CPE autonomously generates an SD-WAN overlay routing table, so that communication reliability and flexibility are improved. An RR specifies an overlay multicast RPF route to the CPE to implement SD-WAN overlay multicast communication, and the CPE does not need to perform path computation autonomously, so that a computing power requirement of the CPE is reduced. An identifier of the CPE and an identifier of a site are carried in a multicast join message to implement the SD-WAN overlay multicast communication. A standard IP header is carried in a multicast service packet to implement the SD-WAN overlay multicast communication, so that generalization, applicability, and compatibility are improved.
