Problems solved by technology

However, since the multicast groups that users often join are constantly changing, network administrators need to frequently adjust the configuration of these static multicast groups to speed up the speed of users joining multicast groups, thereby increasing the maintenance work of network administrators quantity

Embodiment Construction

[0034] The core of the present invention is that the router can automatically determine a batch of the most commonly used static multicast groups at present by monitoring the multicast traffic on the network and the Internet Group Management Protocol (IGMP, Internet Group Management Protocol) to add messages; The host actively joins these commonly used static multicast groups; the purpose of joining the static multicast groups is to guide these multicast streams to the local router. When an interface on the local router needs to receive the multicast stream, it can directly copy and forward it to save the time of directing the required multicast stream to the device. In other words, when users join these common multicast groups, they can quickly forward multicast packets. At the same time, in order to keep the most commonly used static multicast groups at present, these static multicast groups need to be updated regularly.

Abstract

The invention relates to intelligent transmission method for multicast message, which comprises: A. determining common static multicast group of current system by monitoring port traffic and / or adding times and / or adding time; B. active adding current static multicast group on the route interface of static host with intelligent IGMP, and begins to receive the multicast flow; C. when receiving IGMP of current multicast group, it sends the message directly to added user. This invention reduces user adding time delay, increases system response speed, updates timed the current static multicast group, and releases work of network administrator.

Description

technical field [0001] The invention relates to the technical field of multicast in network communication, in particular to an intelligent forwarding method and system for multicast messages. Background technique [0002] With the development of multicast technology, in the existing multicast network, the process from the user joining a group to receiving the corresponding multicast stream is generally like this. First, the user will send an Internet Group Management Protocol (IGMP, Internet Group Management Protocol) join message of a multicast group G to the last router in the same network segment; after receiving the IGMP join message, the router independently The multicast routing protocol (PIM, Protocol Independent Multicast) finds the corresponding multicast source S and establishes a multicast forwarding path to S; finally the router forwards the multicast flow (S, G) to the users who joined the group G, at this time The user can receive the group G data stream.
