Abstract

The embodiment of the invention discloses a method, equipment and system for a multicast control, relating to the technical field of communication. In the invention, multicast permission information is obtained by first network equipment and a retransmission policy of a multicast data stream is arranged on an output port according to the multicast permission information, so that the problem that the multicast data stream is uncontrollable in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for multicast control. Background technique [0002] Multicast is a transmission method, through which a system can simultaneously send the same multicast data stream to multiple users of the same multicast group. In Internet Protocol (IP) multicast technology, Point-to-Point Protocol (PPP) users encapsulate Internet Group Management Protocol (IGMP) packets in Ethernet The Point-to-Point Protocol Over Ethernet (PPPOE) message is sent to the server to request to join the multicast group, and the server authenticates the IGMP message. After the authentication is successful, the user joins the multicast group successfully. The server sends a multicast data stream carrying a multicast virtual local area network (Virtual Local Area Network, referred to as VLAN) identifier. After the multicast data stream arrives at the Layer 2 switching devic...
