Method and device for improving multicast information transmission bandwidth utilization rate

Abstract

The invention provides a method and device for improving the multicast information transmission bandwidth utilization rate. The method includes the steps that if the number of member service modules of a multicast set m is changed to k' from k, a member bitmap of the multicast set m is updated, nodes of the multicast set m are removed from original resource nodes, and whether the number k of original member service modules of the multicast set m is 0 or not is judged; a new member bitmap of the multicast set m is compared with a member bitmap of all the resource nodes, and the nodes of the multicast set m are added in resource nodes in optimal matching with the nodes of the multicast set m; if the number k of the original member service modules of the multicast set m is not 0, information of the new resource nodes where the multicast set m is located and information of the original resource nodes are updated; if the number k of the original member service modules of the multicast set m is 0, the information of the new resource nodes where the multicast set m is located is updated, and using conditions of multicast routing list hardware resources are updated. The method and device can improve the multicast information transmission bandwidth utilization rate of communication equipment and improve the communication quality of multicast information.

Description

Technical field [0001] The present invention relates to multicast information transmission of communication equipment, in particular to a method and a device for improving the utilization rate of multicast information transmission bandwidth. Background technique [0002] Existing communication equipment includes a switching module and a service module. The switching module refers to a device used to exchange traffic and act as data stream forwarding on a communication device; a service module refers to a device used for service processing on a communication device. It uses a distributed architecture. The data flow between each business module is transferred through the switching module. Multicast is a common service method for data circulation between communication devices. Multicast is a communication service in which one sender transmits information to multiple receivers. Current communication equipment generally supports multiple multicast groups, and the multicast group rep...

Problems solved by technology

When the multicast traffic is large, these places are likely to cause congestion of multicast information, which is the bottleneck of multicast communication

[0007] Moreover, in the actual communication equipment, when the convergence ratio R is large and the number of multicast groups of the multicast service is large, the performance of the multicast drops very badly, seriously affecting the communication quality of the multicast information
