Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0045] A method and system for realizing multicast control in a broadband access network provided by the present invention, the main solutions include:

[0046] After the access node receives the user's multicast join request message, it parses the request message to obtain the user ID and the multicast group ID;

[0047] The access node looks up the requested multicast permission in the user multicast permission table according to the acquired user ID and multicast group ID, and if there is a multicast permission record for the user, obtains the corresponding multicast request from the multicast permission table According to the user authority parameter, process the multicast join request according to the user authority ...

Abstract

The invention discloses a method and system for realizing multicast control in a broadband access network. The method comprises the following steps: an access node analyzes a multicast join request message of a user after receiving the request message to obtain user identifications and multicast group identifications; and the access node searches a user multicast authority list for the requested multicast authority according to the obtained user identifications and multicast group identifications, if the multicast authority record of the user exists, the access node obtains the user authority parameter corresponding to the multicast request from the multicast authority list and processes the multicast join request according to the user authority parameter, if the multicast authority record of the user does not exist, the access node sends a user multicast authority configuration request message to a broadband network gateway according to the obtained user identifications and multicast group identifications, and when receiving the multicast configuration response message sent by the broadband gateway, the access node configures the user authority parameter in the user multicast authority list according to the multicast configuration response message and processes the multicast join request according to the configured user authority parameter.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for realizing multicast control in a broadband access network. Background technique [0002] Multicast is a method of packet transmission. Through multicast, the source host can send the same data packet to multiple destination hosts in the same multicast group at the same time. Multicast technology realizes point-to-multipoint efficient data transmission in IP network. Because multicast can effectively save network bandwidth and reduce network load, it is widely used in network video, real-time data transmission, multimedia conference, data copy, game and simulation, etc. It has a wide range of applications in many aspects. [0003] IP multicast includes two types of basic protocols: multicast routing protocols and multicast group management protocols supported between routers and hosts. The multicast group management protocols include IPv4-based IGM...
