| 摘 要： | 分析了RTP协议的特性和多媒体通信中多用户情况下带宽调整的特点，提出了一种基于RTP协议的业务质量动态控制算法对网络带宽进行控制。该算法能对多用户情况下各用户占有的带宽进行调整，平衡各用户占有的带宽，也使得即使有大量用户同时增加带宽，网络也不会明显产生拥塞。平滑了网络带宽，提高了多媒体通信的业务质量。

| Abstract: | After analysing the RTP protocol and the characteristic of adjusting bandwidth under the condition of multiple users, an RTP based algorithm for controlling the quality of multimedia transaction is presented which can dynamically control the network bandwidth. Under the condition of multiple users, the bandwidth can be adjusted, the bandwidth occupied by the users can be balanced and even if a lot of users would increase the transmission rate simultaneously, the network will not become appreciably congested. Such the network bandwidth is smoothed and the quality of multimedia transaction is enhanced. |
