Problems solved by technology

[0015] At the same time, in the prior art, because the IGMP protocol message is sent through the IPoE protocol stack, this address is not a legal user address. Therefore, the device cannot authorize the multicast service according to the user, and cannot realize controllable multicast. It is very unfavorable for operators to conduct business

Embodiment Construction

[0034] The IGMP protocol maintains the information of the multicast group under the interface of the routing device. When the multicast flow arrives at the routing device, it forwards the multicast data to the interface of the routing device. The IGMP protocol needs to maintain an IGMP protocol state machine for each multicast group under the interface of the routing device; the protocol state machine needs to save the information that the system can uniquely identify the user, such as user ID, multicast group address, etc.

[0035] When the multicast stream arrives, the routing device can properly encapsulate the multicast Layer 3 message at Layer 2 according to the above information that can uniquely identify the user, such as the user ID. For example, when a PPPoE user requests broadcasting, the session id and other necessary information can be obtained according to the user ID when forwarding the message. Therefore, the final encapsulated multicast message can be received b...

Abstract

A method of utilizing IGMP protocol to carry out PPP user multicast receiving the first report message by network device, judging whether user is PPP type or not according to source address of said report message, setting said IGMP protocol state unit from no member present state to be member present state for allowing user to carry out on demand multicast.

Description

technical field [0001] The invention relates to multicast technology, in particular to a method for performing PPP user multicast by using IGMP protocol. Background technique [0002] The traditional multicast technology uses the IGMP protocol (Internet Group Management Protocol, Internet Group Management Protocol) to maintain the group membership relationship between router (router) and receiver (receiver). Among them, multicast routing protocols are used, such as PIM-SM (Protocol Independent Multicast-Sparse Mode, Sparse Mode Protocol Independent Multicast), PIM-DM (Protocol Independent Multicast-Dense Mode, Dense Mode Protocol Independent Multicast), DVMRP (Distance Vector Multicast Routing Protocol (Distance Vector Multicast Routing Protocol) etc. maintain the multicast forwarding table, so that the receiver can receive the multicast data message from the multicast source and realize the multicast communication. [0003] The IGMP protocol is a multicast protocol in the ...
