TCP/IP拥塞控制的研究是计算机网络最活跃的领域之一，其目的是解决TCP/IP拥塞控制所面临的自相似性问题、效率问题、公平性问题。文中从控制理论角度对开环与闭环控制拥塞模式进行了阐述，从造成TCP/IP拥塞原因入手，并对其相应的策略做出改进，此外还对闭环拥塞控制的基本策略：许可控制、依赖路由选择、隐式拥塞信令、显式拥塞信令及抑制包策略进行了分析并提出了相应的抑制包策略改进方法，并取得了很好的成效。%Research on TCP/IP congestion control is one of the most active fields in the computer network,its purpose is to solve the problem of self similarity,efficiency,fairness in the TCP/IP congestion control. From the perspective of control theory,the open-loop and closed-loop congestion control model are described,starting from the TCP/IP congestion reasons,and the corresponding strategies to im-prove. In addition,for the basic strategy of closed loop congestion control,such as admission control,routing relying selection,explicit and implicit congestion signaling,and inhibition of package strategy are analyzed and put forward the corresponding control strategy improved methods,which has achieved good results.
