VCP拥塞控制协议加权公平性研究

Research on weighted fairness for VCP protocol

随着卫星网、千兆以太网、光纤网等高带宽时延乘积(Bandwidth-Delay Product,BDP)网络大量接入Internet,传统的、适用于低速网络的TCP拥塞控制协议的各种版本均存在着明显的缺陷。VCP协议是一种易于实现的、适用于高BDP网络的拥塞控制协议。给出了VCP协议对具有不同权限的用户实现加权公平性的一种方法,包括数学模型的建立、加权公平性的参数选择以及仿真实验等问题。

With the rapid growth in the deployment of high Bandwidth-Delay Product（BDP） networks,such as satellite networks, gigabit Ethernets and fiber networks,to the Internet,the traditional TCP congestion control protocol and its variants have significant limitations.VCP congestion control protocol is suitable for high BDP networks and easy to implement.In this paper,a method of weighted fairness for VCP congestion control protocol is presented,including the modeling,the choice of parameters and the simulation for weighted fairness.
