摘要
本文在分析现有的基于集中式MCU实现群组交互的基础上,提出了一种能够自适应群组交互规模变化和QoS要求的网络带宽动态管理和分配机制,给出了实现算法,并在实际中得到测试和应用,取得良好的效果。
In this paper, an adaptive network bandwidth management mechanism is proposed, which is used to allocate and adjust the bandwidth of each node according to current network bandwidth, scale of group, and QoS requirements. Firstly a MCU-centralized multipoint group communication model is introduced, and then some bandwidth management strategies are suggested. Based on the analysis of the bandwidth usages during group communication, the mechanism is described in detail. Finally anapplication example and conclusion are given.
