Abstract: In the Internet, congestion control out of TCP protocol by Additive Increase and Multiplicative Decrease(AIMD) fails to satisfy the need for multimedia communications. To meet the need of multimedia communications in Internet in desirable Quality of Service(QoS), a fresh congestion control mechanism of Study-based Expanded AIMD(SB-EAIMD) rate control with the number of multimedia package loss is put forward in support of the point to point multimedia communication, with detailed research of its operation principle and approaches.

Key words: expanded AIMD, congestion control, multimedia communications

摘要: 在Internet中,主要传输控制协议采用了和式增加积式减少(AIMD)的拥塞控制机制,直接应用该机制不能适应多媒体通信的要求,为了解决好Internet中的多媒体通信以及满足媒体流服务质量的要求,该文针对实时视频传输的实际应用,在点对点的单播速率控制方面和扩展AIMD速率控制基础上,提出一种以丢包为参数具有一定学习能力的速率控制机制即基于学习的扩展AIMD拥塞控制机制,并研究其实现原理和方法。应用表明,该机制具有平滑数据发送速率、降低丢包数等特点。
