Embodiment Construction

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] The terms "first," "second," and similar terms used in the description and claims of this application do not denote any order, quantity, or importance, but are only used to distinguish different components. Likewise, "a" or "an" and the like do not denote a quantitative limitation, but rather denote the presence of at least one.

[0035] First, some terms involved in this application are introduced.

[0036] Multicast, or multicast: refers to a communication mode that implements point-to-multipoint network connections between a multicast source and multiple clients. The multicast source sends the multicast data stream within the group to the clients in need through the switch and / or router. Clients can reque...

Abstract

The application discloses a message transmission method and device, which belong to the technical field of communication. The method includes: receiving a protocol message; determining whether the source MAC address of the protocol message is the same as the physical MAC address of the network device; when the source MAC address is different from the physical MAC address, if the protocol message is a multicast join message or If the leave message is broadcast, the multicast forwarding table item is updated according to the protocol message, and the multicast forwarding table item is used to determine the forwarding address of the data message when the data message is transmitted by the network device. Since each network device on the main link and the backup link can maintain the multicast forwarding table entries according to the protocol message, when the main link fails, the second network device on the backup link can directly use the multicast forwarding entries maintained by itself. The forwarding table entry transmits the data message, without temporarily creating a multicast forwarding table entry according to the protocol message, which improves the speed when the data message is switched to the standby link for transmission.

Description

technical field [0001] The embodiments of the present application relate to the field of communications technologies, and in particular, to a message transmission method and device. Background technique [0002] In network communication using Ethernet, multicast services are becoming more and more common, such as: interactive network television (IPTV), IP video conference services, IP online courses, etc.). In order to improve the reliability of multicast services, a typical multicast system structure will deploy some backup links between the client and the multicast source to form an Ethernet ring network. In this way, when the primary link fails, the backup link can be used to transmit data packets of multicast data. [0003] refer to figure 1 A schematic diagram of the structure of a typical multicast system shown. The multicast system includes a multicast source server 101 , a network device 102 , a network device 103 , a network device 104 , a network device 105 and ...
