摘要
针对P2P应用消耗大量网络带宽而影响互联网传统业务服务质量的问题,提出了一种基于反馈原理及Kal-man算法的P2P流量控制方案。本方案借助控制论中的反馈原理,对互联网中的P2P流量进行调节控制,较好地解决了P2P流量抢占大量网络带宽的问题。仿真研究表明:本方案能抑制过高流量,提高过低流量,使对等端发送速率可快速响应网络状态的变化,有效避免拥塞的发生,并使链路带宽得以充分利用。
With the increasing number of P2P users,P2P applications are consuming most of the Internet bandwidth,otherwise they have a negative effect on traditional Internet applications.In order to solve thwas problem,a P2P traffic control method based on feedback principle and Kalman algorithm was presented.By means of feedback principle in control theory and Kalman algorithm,the P2P traffic can be regulated and controlled properly.The experimental results show it can not only reduce the high P2P traffic,but also improve the low P2P traffic.It can make the peers to respond to the changes of network status rapidly and utilize the bandwidth sufficiently.
