Embodiment Construction

[0024] A multicast communication method, system and multicast communication device according to an embodiment of the present invention solve the problem of existing problems by selecting a multicast communication device from among multiple multicast communication devices in the user VLAN to which the user belongs to forward messages. In the user dual-homing network, the user receives data repeatedly, resulting in a technical problem of service unavailability.

[0025] The technical solutions of the multicast communication method, system, and multicast communication device in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] refer to figure 2 , is a flowchart of a multicast communication method provided by an embodiment of the present invention. In the embodiment of the present invention, the user belongs to at least two multicast communication devices in the same user VLAN, and the method includ...

Abstract

An embodiment of the invention discloses a multicast communication method, wherein a user belongs to at least two multicast communication devices in a user virtual local area network VLAN, comprising: voting in the multicast communication devices belonging to the user, and selecting one multicast communication device; transmitting message transmitted by VLAN through the selected multicast communication devices. Accordingly, the embodiment of the invention discloses a multicast communication system and a multicast communication device, through the multicast communication method, the system andthe multicast communication devices, the problem of receiving repeated multicast data when the user is in double adscription or multi-adscription is solved, thereby increasing reliability of communication.

Description

technical field [0001] The present invention relates to multicast communication technology, in particular to a multicast communication method, system and multicast communication equipment. Background technique [0002] With the development of communication technology, there are three communication modes in the current network: unicast, broadcast, and multicast. Among them, multicast appears the latest, but has the advantages of both unicast and broadcast, and has the most development prospects. [0003] In the current multicast communication, the network layer adopts the Internet Group Management Protocol (IGMP). The IGMP protocol is a signaling mechanism for hosts to routers used by IP multicast on the terminal network. It is divided into two functional parts : host side and router side. The link layer adopts the IGMPSnooping protocol, and maintains the outgoing port information of the multicast packets by listening to the multicast protocol packets sent between the upper ...
