【摘要】：從當(dāng)今世界互聯(lián)網(wǎng)的發(fā)展情況來看,IPv6毋庸置疑會是將來互聯(lián)網(wǎng)的主流趨勢。雖然IPv6克服了IPv4的諸多弊端,但現(xiàn)如今大部分電子產(chǎn)品及服務(wù)設(shè)備中IPv4還是主流技術(shù),所以從IPv4到IPv6的過渡不能一蹴而就,需要循序漸進(jìn)。因此,各種過渡技術(shù)應(yīng)運而生,如雙協(xié)議棧技術(shù)、隧道技術(shù)和協(xié)議翻譯技術(shù)。NAT64技術(shù)正是在這種背景下產(chǎn)生的,本文研究了基于NAT64的IPv4到IPv6過渡技術(shù)方案的設(shè)計與實現(xiàn),主要工作如下： 首先介紹了IPv6協(xié)議的發(fā)展背景,分析了目前主流的IPv4到IPv6過渡技術(shù),包括雙協(xié)議棧技術(shù)、隧道技術(shù)和協(xié)議翻譯技術(shù),并對各技術(shù)優(yōu)缺點進(jìn)行了詳細(xì)的對比。 其次分析了NAT64和DNS64技術(shù)原理和設(shè)計要求,在此基礎(chǔ)上,給出了過渡技術(shù)方案的總體框架設(shè)計,并進(jìn)行了子模塊劃分,包括翻譯模塊(分別為TCP、UDP和ICMP)、表項管理模塊、表項超時模塊和配置管理模塊。進(jìn)而論述了NAT64控制流和數(shù)據(jù)流的設(shè)計以及相關(guān)的關(guān)鍵數(shù)據(jù)結(jié)構(gòu)。在LINUX操作系統(tǒng)下,給出了基于NAT64過渡技術(shù)方案的詳細(xì)設(shè)計與實現(xiàn),詳細(xì)介紹了各個子模塊的設(shè)計與實現(xiàn)。 最后對NAT64過渡方案進(jìn)行了部署和測試,包括命令行測試(如NAT64前綴配置命令、地址池配置命令及表項超時配置命令),功能測試(如地址協(xié)議翻譯功能、表項超時功能)等,并搭建實驗環(huán)境對已經(jīng)實現(xiàn)的各個功能模塊進(jìn)行測試,對具體的實施結(jié)果進(jìn)行了分析,結(jié)果表明本方案達(dá)到了預(yù)期的設(shè)計要求。 本文分析了IPv6的優(yōu)點以及國內(nèi)外IPv6實現(xiàn)的現(xiàn)狀,針對目前IPv4到IPv6的主流過渡技術(shù)進(jìn)行了分析,并總結(jié)出各自的優(yōu)缺點及適用的網(wǎng)絡(luò)。針對NAT64過渡方案進(jìn)行了設(shè)計和實現(xiàn),達(dá)到了IPv6網(wǎng)絡(luò)客戶端與IPv4網(wǎng)絡(luò)服務(wù)器通信的目的。
[Abstract]:Judging from the development of the Internet in the world today, IPv6 will undoubtedly be the mainstream trend of the Internet in the future. Although IPv6 overcomes many disadvantages of IPv4, nowadays IPv4 is still the mainstream technology in most electronic products and service devices, so the transition from IPv4 to IPv6 cannot be accomplished overnight. Therefore, a variety of transition technologies emerge as the times require, such as dual-protocol stack technology, tunnel technology and protocol translation technology. NAT64 technology is produced under this background. This paper studies the design and implementation of IPv4 to IPv6 transition technology based on NAT64. The main work is as follows: firstly, the development background of IPv6 protocol is introduced, and the current mainstream technology of transition from IPv4 to IPv6 is analyzed, including dual-protocol stack technology, tunnel technology and protocol translation technology. The advantages and disadvantages of each technology are compared in detail. Secondly, the technical principle and design requirements of NAT64 and DNS64 are analyzed. On the basis of this, the overall framework design of the transition technology scheme is given, and the sub-modules are divided into three modules, including translation module (TCP,UDP and ICMP), table item management module). Table item timeout module and configuration management module. Furthermore, the design and key data structure of NAT64 control flow and data stream are discussed. Based on the LINUX operating system, the design and implementation of the transition technology scheme based on NAT64 are presented, and the design and implementation of each sub-module are introduced in detail. Finally, NAT64 transition scheme is deployed and tested, including command-line test (such as NAT64 prefix configuration command, address pool configuration command and table item timeout configuration command), function test (such as address protocol translation function, table item timeout function), etc. The experimental environment is set up to test the functional modules that have been implemented, and the concrete implementation results are analyzed. The results show that this scheme meets the expected design requirements. This paper analyzes the advantages of IPv6 and the status quo of IPv6 implementation at home and abroad, analyzes the mainstream transition technology from IPv4 to IPv6, and summarizes their advantages and disadvantages as well as applicable networks. The NAT64 transition scheme is designed and implemented to achieve the purpose of communication between IPv6 network client and IPv4 network server.
