    在称为信息时代的今天,网络已经深入到千家万户,各行各业,导致网络中的数据流量越来越庞大,网络状况出现越来越多问题,而在许多不同通信规则的管控下,数据遵循着不同的传输协议在网络中进行交互而发生在某些情况下出现数据丢失,堵塞等一系列难以预知的情况。例如TCP协议的重传在发送方不知道网络已经拥挤或接收端来不及处理的情况下认为数据包并没有传送到目的而再次重传进而更加重了网络负担最重导致网络的崩溃。例如UDP协议在没有拥塞管控的情况下仍旧根据有多少发多少,不管接收方是否准确接收到的前提下疯狂占据着已经不堪重负的网络管道,进行着不公平的资源抢占。因此,对于网络拥塞控制的研究已经越来越被人们重视,如何合理利...Abstract Today, network has been deeply involved in our modern society.
