Problems solved by technology

Therefore, this will lead to different forwarding information and routing table structures of multicast routing, so the meanings to be identified by the index are not exactly the same, which is not convenient for cross-platform operation

Embodiment Construction

[0049] In order to deeply understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] Such as figure 1 As shown, the present invention is realized by the multicast route aggregation module. This module is embedded in the traditional multicast routing processing module and is used to realize the aggregation of multicast forwarding routes. It is necessary to have corresponding processing modules in the multicast forwarding layer and the multicast protocol layer. The main functions of the multicast route aggregation module at the protocol layer are: the outbound interface aggregation of multicast forwarding routes, Index allocation and dynamic management, the management and synchronization of the mapping relationship between Index and outbound interface list, and the aggregation of cross-platform virtual machines. The main function of the multicast route aggregation mod...

Abstract

The invention relates to a multicast transfer route collect method, which comprises: the protocol layer generates the multicast transfer route list formed by several multicast route items, while the item comprises multicast source address, multicast group address, multicast route operation mark, multicast access interface, and index; the index is globe effect and unique, to represent the interface list, while the indexes are same based on the same interface lists; at the same time, the protocol layer will generate the projection between the index and the represented interface list; the transfer layer generates several index local outlet interface project list relative to the interface plate, formed by globe index and the effective outlet interface list of local interface plate. With said invention, the memory space occupied by multicast route can be reduced, and the large-capacity multicast transfer route can be aggregated into the multicast transfer route supported by present hardware chip capacity.

Description

technical field [0001] The invention relates to the field of IP network multicast, in particular to a method for aggregating multicast forwarding routes when implementing IP multicast in wired and wireless IP communication systems. Background technique [0002] At present, IP multicast technology can effectively solve the problem of single-point transmission and multi-point reception, and can realize efficient point-to-multipoint data transmission in the IP network, which can greatly save network bandwidth and reduce network load. As a communication method parallel to unicast and broadcast, the significance of multicast is not limited to this. More importantly, it can easily provide some new value-added services with the multicast feature of the network, including Internet information service fields such as online live broadcast, Internet TV, distance education, telemedicine, Internet radio, and real-time video conferencing. Due to the above-mentioned characteristics of IP ...
