可靠UDP傳輸之研究與實作

The Research and Implement of Reliable-UDP data transfer

指導教授 : 黃紹華

摘要


隨著網路通訊的進步發展,網路通訊協定有很多種,一般基本常用的協定為UDP與TCP。而UDP與TCP各有其優缺點,UDP擁有快速傳輸的傳輸速度與穿越NAT的特性,TCP擁有可靠的傳輸、壅塞控制等特性。為了達到能穿越NAT的可靠傳輸,於是取了UDP與TCP的優點生成新的通訊協定─可靠的UDP傳輸。 本論文主要目標為如何實作可靠的UDP,讓它達到如TCP一樣的可靠傳輸,且擁有能在網路環境不好的時候也還能傳輸的壅塞控制,並會與現有的通訊協定TCP、UDT在不同的網路環境情形做比較和分析。 本論文所提出的可靠UDP傳輸具有以下特色: 1.壅塞控制 2.資料重傳 3.有序傳輸

With the development of network communications, there are many types of network protocols, which are commonly used protocol is UDP and TCP. The UDP and TCP have advantages.UDP has fast transmission speed and NAT traversal feature. TCP has reliable data transfer and congestion control. In order to achieve reliable transmission can traverse NAT, so take advantage of the UDP and TCP to generate a new protocols "Reliable-UDP data transfer". The purpose of this paper is how to implement reliable UDP, let it achieve reliable transmission and congestion control. It will compare with TCP and UDT in different network environments. Reliable-UDP data transfer proposed in this paper has the following features: 1.congestion control 2.retransmission 3.Sequential transmission
