对TCP/IP计算机网络拥塞控制的研究

为提升计算机的网络性能,更好地避免拥塞现象的发生,需要对其进行必要的技术控制。鉴于此,对基于TCP/IP协议的网络拥塞控制方法进行分析。在TCP拥塞控制中主要采用TCP Tahoe,TCP Reno,TCP New Reno以及TCP Sack四种方法,其中TCP New Reno对快速恢复算法进行了改进,通过对TCP协议中的Reno进行可视化处理,实行对网络拥塞的有效管理。而IP拥塞控制方法则分为FIFO,FQ和WFQ,RED以及ECN四种类型,通过队列调度管理方式实现了对网络拥塞的有效管理。

Research on TCP/IP computer network congestion control

To enhance the performance of the computer network and avoid the occurrence of the congestion phenomenon,it is necessary to carry out the effective technical control. In view of this,the network congestion control methods based on TCP/IP protocol are analyzed. Four methods of TCP Tahoe,TCP Reno,TCP New Reno and TCP Sack are used for TCP congestion control;in which fast recovery algorithm was improved by means of TCP New Reno. The visualization processing can be per-formed through the Reno in TCP protocol to implement the effective management of network congestion. The IP congestion con-trol method can be divided into FIFO,FQ/WFQ,RED and ECN to realize the effective management of network congestion by queue scheduling management pattern.
