Problems solved by technology

[0004] In the traditional multicast technology, since the multicast control plane needs to build a multicast distribution tree and a multicast routing table based on many complex multicast protocols, the multicast control plane builds and maintains the multicast distribution tree and multicast High pressure on routing tables, etc.

Abstract

The present application provides a method and device for forwarding a multicast message, which may include: when receiving a multicast notification message sent by a DR device on the receiver side, extracting the multicast group address and The router of the DR device on the receiver side that binds the multicast group address identifies the Router ID and records it; when receiving the multicast message sent by the multicast source device to the multicast group address, it is determined to bind the multicast group The segment routing SR label stack corresponding to the Router ID of the address; the SR labels of all forwarding devices passing through the Router ID are recorded in the SR label stack; the multicast message is encapsulated into SR packets are forwarded with labels. Using the method provided by this application does not need to maintain a large number of complex multicast protocols, and can improve the forwarding efficiency of multicast messages.

Description

technical field [0001] The present application relates to the field of computer communication, in particular to a method and device for forwarding multicast messages. Background technique [0002] Multicast technology can effectively solve the problem of single-point transmission and multi-point reception, thereby realizing efficient data transmission from point to multipoint in the network, saving a lot of network bandwidth and reducing network load. [0003] Multicast usually consists of a multicast control plane and a multicast forwarding plane. In the traditional multicast technology, the multicast control layer needs to be based on IGP (Interior Gateway Protocol, Interior Gateway Protocol), PIM (Protocol Independent Multicast, Independent Multicast Protocol), IGMP (Internet Group Management Protocol, Internet Group Management Protocol) and other groups The multicast protocol builds a multicast distribution tree and a multicast routing table, etc., and the forwarding la...
