基于丢包和网络测量的TCP拥塞控制算法研究综述

Overview of TCP Congestion Control Algorithm Based on Packets Loss and Network Measurement

拥塞控制一直是网络通信领域的重要研究课题,它可以避免因网络拥塞而导致的传输质量严重下降,同时确保网络带宽的高效利用。TCP在互联网的发展过程中扮演着不可或缺的重要的角色,是实现网络拥塞控制的重要途径。随着互联网技术的发展,提出了多种TCP拥塞控制算法,其中基于丢包和网络测量两类算法最为典型。文章梳理了TCP拥塞控制算法的发展历程,并详细分析了基于丢包和基于网络测量两类算法的原理及优缺点。

Congestion control has always been an important research topic in the field of network communication.It can avoid the serious reduction in transmission quality caused by the network congestion and ensure the efficient bandwidth utilization.TCP plays an indispensable role in the development of the Internet.It is also an important way to realize network congestion control.With the development of the Internet technology,a variety of TCP congestion control algorithms have been proposed,among which two typical kinds of algorithms include packet loss and network measurement.This paper describes the development history of TCP congestion control algorithms,and analyzes the principles,advantages and disadvantages of two kinds of algorithms,i.e.,packet loss-based and network measurement-based,in details.
