摘要
基于UDP业务数据在互联网的剧增导致了严重的网络拥塞。首先通过OPNET仿真平台建立起适当的仿真模型,通过仿真阐明了UDP协议不具备拥塞控制机制是网络拥塞产生的最根本原因,并且同一链路过多的UDP数据还可能导致对TCP数据流的不公平性;然后提出了在通信子网节点进行IP网络拥塞控制方法,并且通过仿真数据也证明了在通信子网进行IP拥塞控制是可行的;最后对将来新的拥塞控制技术进行展望。
The increase of the data based on UDP on the internet results in serious network congestion.This paper establishes an appropriate simulation model by OPNET,and shows that UDP protocol doesn＇t have the congestion control mechanism,which is the most fundamental reason of network congestion,and the much more UDP data in the one link may lead to unfairness for TCP traffic flow,and then puts forward a method to control congestion in the nodes of the networks,and shows the feasibility of this method by OPNET simulation,at last,it looks into the future of the congestion control technology.
