【摘要】：隨著IPv4地址的日益減少,使用IPv6地址替代IPv4地址已成為解決地址匱乏問(wèn)題的關(guān)鍵,這就使IPv4向IPv6過(guò)渡成為越來(lái)越重要的課題。由中國(guó)電信提出的Lightweight address family transition for IPv6(LAFT6)技術(shù),集合多種IPv6過(guò)渡技術(shù)的優(yōu)勢(shì),實(shí)現(xiàn)了輕量級(jí)的IPv4到IPv6過(guò)渡。目前,已經(jīng)有多家設(shè)備廠商對(duì)該技術(shù)的家庭網(wǎng)關(guān)進(jìn)行研究與實(shí)現(xiàn)。LAFT6技術(shù)已經(jīng)開(kāi)始在江蘇、湖南電信試點(diǎn)運(yùn)行,有相關(guān)設(shè)備商對(duì)LAFT6家庭網(wǎng)關(guān)進(jìn)行研發(fā)和批量生產(chǎn)。但由于沒(méi)有開(kāi)源代碼,使得一些科研機(jī)構(gòu)在研究LAFT6技術(shù)遇到問(wèn)題時(shí),沒(méi)有很好的參照,進(jìn)而影響該技術(shù)的發(fā)展。同時(shí),由于LAFT6技術(shù)自身的特點(diǎn),家庭網(wǎng)關(guān)沒(méi)有很好的支持NAT穿越。本課題設(shè)計(jì)實(shí)現(xiàn)的LAFT6家庭網(wǎng)關(guān)可以在這些方面提供一定的幫助。 本文將實(shí)現(xiàn)和改進(jìn)基于LAFT6技術(shù)的家庭網(wǎng)關(guān),完成編碼,并在實(shí)際的網(wǎng)絡(luò)環(huán)境中進(jìn)行系統(tǒng)測(cè)試。論文主要完成了三項(xiàng)工作。第一步,分析了與LAFT6技術(shù)相關(guān)的RFC文檔和Draft文檔,理解LAFT6技術(shù)的工作流程。重點(diǎn)關(guān)注家庭網(wǎng)關(guān)所需要實(shí)現(xiàn)的功能,設(shè)計(jì)功能模塊實(shí)現(xiàn)LAFT6家庭網(wǎng)關(guān)的基本功能。同時(shí)根據(jù)現(xiàn)實(shí)需求,改進(jìn)LAFT6家庭網(wǎng)關(guān),并在相關(guān)領(lǐng)域進(jìn)行探索。第二步,設(shè)計(jì)并實(shí)現(xiàn)LAFT6家庭網(wǎng)關(guān)。使用C語(yǔ)言開(kāi)發(fā),并移植在平臺(tái)為OpenWrt的路由器上。代碼開(kāi)發(fā)包括：家庭網(wǎng)關(guān)的上層PCP協(xié)議開(kāi)發(fā)；家庭網(wǎng)關(guān)的底層模塊開(kāi)發(fā)；家庭網(wǎng)關(guān)與UPnP結(jié)合的模塊開(kāi)發(fā)。第三步,對(duì)家庭網(wǎng)關(guān)進(jìn)行測(cè)試。從功能測(cè)試和性能測(cè)試兩方面對(duì)家庭網(wǎng)關(guān)進(jìn)行系統(tǒng)地測(cè)試。
[Abstract]:With the increasing decrease of IPv4 addresses, using IPv6 addresses to replace IPv4 addresses has become the key to solve the problem of address scarcity, which makes the transition from IPv4 to IPv6 become more and more important. The Lightweight address family transition for IPv6 LAFT6 technology, proposed by China Telecom, integrates the advantages of various IPv6 transition technologies and realizes the transition from lightweight IPv4 to IPv6. At present, many equipment manufacturers have studied and implemented the home gateway of this technology. LAFT6 technology has already started to run in Jiangsu and Hunan Telecom pilot projects. There are related equipment manufacturers to research and develop and mass production of LAFT6 home gateway. However, due to the lack of open source code, some scientific research institutions encounter problems in the research of LAFT6 technology, which will affect the development of the technology. At the same time, because of the characteristics of LAFT6 technology, home gateway does not support NAT traversal well. The LAFT6 home gateway designed and implemented in this paper can provide some help in these aspects. This paper will implement and improve the home gateway based on LAFT6 technology, complete the coding, and test the system in the actual network environment. The thesis mainly completes three works. The first step is to analyze the RFC documents and Draft documents related to LAFT6 technology and understand the workflow of LAFT6 technology. Focus on the home gateway needs to achieve the functions, design functional modules to achieve the basic functions of the LAFT6 home gateway. At the same time, according to the actual needs, improve the LAFT6 home gateway, and explore in related areas. The second step is to design and implement LAFT6 home gateway. C language development, and transplanted to the platform for OpenWrt router. The code development includes: the development of the upper PCP protocol of the home gateway; the development of the bottom module of the home gateway; and the module development of the combination of the home gateway and the UPnP. The third step is to test the home gateway. The home gateway is systematically tested from two aspects: function test and performance test.
