TCP協(xié)議族擁塞控制機(jī)制分析與研究
摘要：計(jì)算機(jī)網(wǎng)絡(luò)在過(guò)去10幾年中經(jīng)歷了爆炸式的增長(zhǎng)，隨之而來(lái)的是越來(lái)越嚴(yán)重的網(wǎng)絡(luò)擁塞問(wèn)題，TCP中的擁塞控制算法也在隨之不斷的改進(jìn)。本文論述了幾種主流的TCP擁塞控制算法對(duì)網(wǎng)絡(luò)性能的影響。首先討論了TCP擁塞控制機(jī)制及其算法的設(shè)計(jì)，接著介紹和分析了現(xiàn)有的兩種改進(jìn)的TCP算法——Reno和Vegas，在此基礎(chǔ)上，我們進(jìn)1步分析了當(dāng)前1種新的TCP協(xié)議——FAST TCP，該協(xié)議主要針對(duì)高速長(zhǎng)延遲網(wǎng)絡(luò)進(jìn)行了TCP擁塞控制算法的重新設(shè)計(jì)，論文討論了FAST TCP的算法設(shè)計(jì)思路，并從源代碼的角度分析了算法實(shí)現(xiàn)。最后我們分別在局域網(wǎng)和廣域網(wǎng)中用具體的實(shí)驗(yàn)測(cè)試了FAST TCP和傳統(tǒng)TCP擁塞算法的性能差異。

Analysis and Research on TCP Congestion Control Mechanism
Abstract: With the rapid development of Internet, the problem of Internet congestion becomes more and more outstanding. At the same time, the TCP congestion control algorithm has been continuously improved. This thesis discusses several kinds of classic TCP congestion control algorithms’ influence to the network performance. First we discusses the TCP congestion control mechanism and the design of algorithm, then we introduce and analyze two kinds of improved TCP algorithm - - Reno and Vegas, on this basis, we further analyze a new TCP protocols- - FAST TCP, which aims at the high-speed long delay network and redesigns the TCP congestion control algorithm. This thesis discusses the FAST TCP algorithm’s design mentality, and uses the source code to analyze realization of the algorithm. Finally we design several experiments to test the performance between FAST TCP and the traditional TCP congestion algorithm in LAN and WAN.
Key words: TCP congestion control; Reno; Vegas; FAST TCP
