基于网络效用最大化的多路径网络拥塞控制研究

The Research of Multi-path Congestion Control Based on Network Utility Maximization

随着互联网的飞速发展,互联网用户和应用都在快速增长,对于网络服务质量的要求也越来越高,拥塞控制已经成为一个十分重要的问题.基于网络效用最大化的模型研究了多路径网络的拥塞控制问题,将此问题建模为基于用户发送速率的凸规划问题,基于对偶分解得到了分布式的求解方法,仿真结果验证了算法的收敛性.研究内容对多路径的TCP开发具有一定的参考意义.

With the rapid development of Internet,users and applications are emerging.The requirements of QoS are getting higher and higher.Congestion control has become a very important issue.The article study the multi-path network congestion control problem based on network utility maximization model.This problem is modeled as convex programming based on the user＇s sending rate and a distributed method is proposed using dual decomposition.The simulation results demonstrate the algorithm convergence.The content of the article may help developing a new multi-path TCP.
