几种TCP协议下F、G函数的研究

Research of F/G Function under Several TCP Protocols

随着网络技术的不断提高,一些新型的高速网络投入使用,产生了一系列如TCP拥塞控制算法,其中Reno协议、Vegas协议、RED协议以不同的方式解决了网络拥塞的问题。通过在以上3种协议模型下对F、G函数进行推导,用对偶方程求解的方法,比较3种协议的优劣,为网络模型的建立打下基础。

With the improvement of network technology,a lot of new- type fast networks are realized,and series of TCP congestion algorithms are found. The Reno protocol, Vegas protocol and RED protocol can all solute the problem of network congestion. This paper focuses on those three algorithms,argues the F,G functions under the protocol model, compares the ad- vantages through those three protocols using the method of duality equation,and makes the groundwork for establishing the network model.
