Example Embodiment

[0048] The technical solution in this application will be described below in conjunction with the drawings.

[0049] The technical solutions of the embodiments of the present application can be applied to support Internet protocol version 6 (IPv6) functions and segment routing version 6 (segment routing version 6) in a multicast virtual private network (VPN). , SRv6) function or BIER IPv6 forwarding function in one or more function nodes. Among them, SRv6 functions include IPv6 functions, and BIER IPv6 forwarding functions include encapsulation of BIER IPv6 messages, forwarding of BIER IPv6 messages, and decapsulation and transmission of BIER IPv6 messages. In this application, the BIERIPv6 message may also be called a BIER message.

[0050] Specifically, the above-mentioned node may be a node capable of realizing BIER message encapsulation, BIER message forwarding, and BIER message decapsulation, such as a router or a switch. Among them, the aforementioned nodes may also be refe...

Abstract

The invention provides a message forwarding method, a message sending device and a message receiving device. The method comprises the following steps: a first node configures a first identification and a first IPv6 address of a first VPN on a control plane, wherein the first identification corresponds to the first IPv6 address; the first node carries the first identification and the first IPv6 address in a first indication message and sends the first indication message to a second node; the second node firstly determines a second identification satisfying a preset corresponding relationship with the first identification in the second node according to locally configured information of the first VPN and the first identification in the first indication message, and then establishes a corresponding relationship between the first IPv6 address and the second identification; and the first node encapsulates a multicast data message belonging to the first VPN based on the first IPv6 address ona forwarding plane to obtain a BIER message to be forwarded and send the BIER message, so that the message encapsulation and forwarding performance can be improved.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a message forwarding method, a device for sending a message, and a device for receiving a message. Background technique [0002] Internet protocol (Internet protocol, IP) multicast technology realizes efficient point-to-multipoint data transmission in IP network, can effectively save network bandwidth and reduce network load, so IP multicast technology is used in real-time data transmission, multimedia conference, data Copying, Internet protocol television (Internet protocol television, IPTV), games, and emulation are widely used in many aspects. At present, multicast technology is generally implemented by protocol independent multicast (PIM) protocol or multicast source discovery protocol (multicast source discovery protocol, MSDP) protocol, etc. A common feature of these multicast protocols is that a control Plane multicast tree, using this multicast tree t...
