【摘要】：随着IPv4地址的日益减少,使用IPv6地址替代IPv4地址已成为解决地址匮乏问题的关键,这就使IPv4向IPv6过渡成为越来越重要的课题。由中国电信提出的Lightweight address family transition for IPv6(LAFT6)技术,集合多种IPv6过渡技术的优势,实现了轻量级的IPv4到IPv6过渡。目前,已经有多家设备厂商对该技术的家庭网关进行研究与实现。LAFT6技术已经开始在江苏、湖南电信试点运行,有相关设备商对LAFT6家庭网关进行研发和批量生产。但由于没有开源代码,使得一些科研机构在研究LAFT6技术遇到问题时,没有很好的参照,进而影响该技术的发展。同时,由于LAFT6技术自身的特点,家庭网关没有很好的支持NAT穿越。本课题设计实现的LAFT6家庭网关可以在这些方面提供一定的帮助。本文将实现和改进基于LAFT6技术的家庭网关,完成编码,并在实际的网络环境中进行系统测试。论文主要完成了三项工作。第一步,分析了与LAFT6技术相关的RFC文档和Draft文档,理解LAFT6技术的工作流程。重点关注家庭网关所需要实现的功能,设计功能模块实现LAFT6家庭网关的基本功能。同时根据现实需求,改进LAFT6家庭网关,并在相关领域进行探索。第二步,设计并实现LAFT6家庭网关。使用C语言开发,并移植在平台为OpenWrt的路由器上。代码开发包括：家庭网关的上层PCP协议开发；家庭网关的底层模块开发；家庭网关与UPnP结合的模块开发。第三步,对家庭网关进行测试。从功能测试和性能测试两方面对家庭网关进行系统地测试。
[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.
