Embodiment Construction

[0057] The core of the present invention is that the first hop router connected to the multicast source in the network generates a multicast routing table entry containing the IP address S of the multicast source and the IP address G of the multicast group according to the multicast flow sent by the multicast source (S, G), when the IP address of the multicast source in the multicast flow is in the same network segment as the local interface address of the first-hop router, the first-hop router regards itself as a candidate RP for the multicast group, and the RP address It is the loopback port address of the first-hop router or the interface address between the first-hop router and any other router.

[0058] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0059] The present invention is based on the PIM SM protocol, which is t...

Abstract

The invention discloses a method for configuring a protocol-independent multicast sparse mode protocol convergence point. The same network segment; when the IP address of the multicast source and the local interface address are in the same network segment, the first-hop router takes itself as the candidate rendezvous point RP of the multicast group. The invention also discloses a device for configuring a protocol-independent multicast sparse mode protocol convergence point, comprising a detection unit and an RP dynamic configuration unit. The invention can reduce a lot of manual configuration of multicast group IP addresses on the RP router, so that the whole configuration has greater flexibility, so as to meet wider demands.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a device for configuring a convergence point of a protocol-independent multicast sparse mode protocol. Background technique [0002] In the past two years, the safety project has been highly valued by the state, and huge sums of money have been invested in various cities to build safety projects required by this harmonious society. The security project requires each city to set up monitoring systems at key points such as various institutions and traffic arteries, and use massive storage systems to store recorded video data. At present, a typical urban safety project configuration plan is: the municipal bureau has 20 sub-bureaus, each sub-bureau has 25 police stations, and each police station has 1,000 cameras. Each camera is a multicast source, which is assigned a multicast group address for monitors to order; each camera is also a unicast source, whic...
