Allocation method of distributed multipoint control unit in IP network multimedia conference system

Abstract

This invention provides an arrangement method of IP multimedia meeting system distribution control units, which comprises the following steps: to align two or more multi-points control units in the multimedia meeting system; the said multi-point control units are arranged in the point or net range of the meeting system; to rank the point or net range of the said meeting system; to align at least one control unit to the point or range with high intensity after ranking.

Description

technical field [0001] The invention relates to a multimedia conference system operating on an IP service network, in particular to a deployment method of a distributed multipoint control unit in an IP network multimedia conference system. Background technique [0002] The multimedia conference system connects multiple multimedia conference terminals located in different places through the communication network, and under the control of the multi-point control unit (Multi-point Control Unit, MCU), it allows the participants to communicate in multimedia ways such as images, voice and data. . The multimedia conference system includes a multimedia conference terminal, a multipoint control unit and a gatekeeper (Gatekeeper, GK). The multimedia conference terminal conducts two-way multimedia communications such as image, voice and data with other terminals, multipoint control units and gatekeepers. The multipoint control unit provides control over multiple multimedia conference...

Problems solved by technology

[0004] 1. Since the multi-point control unit is deployed in the multimedia conference system in a centralized manner, the processing and switching load of the multi-point control unit is heavy, especially when there are many system users and multiple conferences are carried out at the same time, this limits the system. The scale, unable to set up a large-scale multimedia conference system;

[0005] 2. During a multipoint conference, the images, sounds and data sent by the participating terminals are concentrated in the multipoint control unit, and after image and voice processing (multi-picture processing, speed mixing, audio mixing, etc.) by the multipoint processing module , and then forwarded to each participating terminal, as shown by the solid line in Figure 1, this will inevitably cause a large data flow on the node where the multipoint control unit is located, occupying more bandwidth resources, especially when there are a large number of There may be a large amount of traffic on the Internet, and in severe cases, it will cause network congestion
