Abstract

Provided are a message forwarding method, device and system, the method comprising: a first network device obtains a first message, the first message comprising a multicast message; the first network equipment determines a next-hop destination address DA of the multicast message according to a source address SA and a first corresponding relation, the SA is used for identifying a multicast path corresponding to the multicast message, and the first corresponding relation comprises the SA and the next-hop DA of the first network equipment on the multicast path; the first network equipment obtains a second message according to the next-hop DA, wherein the second message is a unicast message obtained by carrying out IPv6 encapsulation on the multicast message; and the first network equipment forwards the second message along the multicast path according to the next hop DA. According to the technical scheme provided by the invention, waste of address space can be reduced.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010671831.7 and the title of the invention "a multicast forwarding method, device and system" submitted to the China Patent Office on July 14, 2020, the entire contents of which are incorporated by reference In this application. technical field [0002] The present application relates to the field of network communication, and more specifically, relates to a method, device and system for message forwarding. Background technique [0003] Multicast (multicast) is a method of sending data to multiple recipients on a transmission control protocol (transmission control protocol, TCP) / Internet protocol (internet protocol, IP) network at the same time in an efficient manner by using a multicast address. The data transmission method of the user. The multicast source sends the multicast flow to the multicast group members in the multicast group through the link in the network...
