Abstract

The invention provides a method and a device for pruning a forwarding path of multicast data and network equipment. The method comprises the steps of: acquiring a protocol-independent multicast neighbor list of all routers whose sharing network segments belong to the same multicast group, wherein the protocol-independent multicast neighbor list comprises protocol-independent multicast neighbor relationships of all the routers and forwarding identifications of the multicast data of all the routers, the forwarding identifications of the multicast data are used for determining whether forwardingthe multicast data of the multicast group or not; and determining the number of downstream neighbor routers of any router according to the protocol-independent multicast neighbor relationships and pruning the forwarding path of the multicast data according to the number of the downstream neighbor routers of any router and the forwarding identifications of the multicast data of each downstream neighbor router of any router. The invention shortens the pruning delay of the forwarding path of the multicast data in the sharing network segments and saves network bandwidth resources and the multicast router resources.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a pruning processing method, device and network equipment for multicast data forwarding paths. Background technique [0002] Multicast is widely used in IP networks, and is mainly used in services such as video-on-demand and video conferencing. Compared with unicast technology and broadcast technology, multicast technology has better advantages in terms of network bandwidth usage, server load, and network deployment. [0003] The protocol independent multicast-dense mode (Protocol Independent Multicast-Dense Mode, PIM-DM) protocol is a widely used multicast routing protocol at present. In the PIM-DM protocol, a flood and prune mechanism is used to establish a multicast tree. The PIM-DM protocol assumes that when a multicast source starts to send a multicast data packet, all devices on the network need to receive the packet, so the packet is forwarded to each devi...
