摘要： 基于Internet的以UDP为传输协议的实时多媒体数据传输,需要在保证实时性和可靠性基础上,能够与Internet其他服务所使用的TCP协议合理共享有限的带宽,在研究多种拥塞控制算法的基础上,提出了一种简单实用的TCP友好拥塞/速率控制算法,并将该算法应用在一个实用的IP电话软件中,取得了预期的效果。

Abstract: Real-time multimedia data transmission through Internet is based on UDP. The transmission must be real-time and reliable, it also should be fairness with the domain protocol TCP used by other services in Internet while sharing the limited bandwidth with TCP. A simple and practical TCP-friendly congestion/rate control algorithm is presented based on comparing and analysing many congestion control algorithms, and it has been used in our software. The results show that the algorithm works well.
