【摘要】：隨著互聯(lián)網(wǎng)用戶(hù)數(shù)量的不斷增加,用戶(hù)對(duì)互聯(lián)網(wǎng)的多業(yè)務(wù)支持能力、安全性及移動(dòng)性的要求越來(lái)越高,對(duì)以IPv6為基礎(chǔ)的下一代互聯(lián)網(wǎng)的研究迫在眉睫。但由于網(wǎng)絡(luò)環(huán)境的復(fù)雜性以及當(dāng)前IPv4業(yè)務(wù)覆蓋范圍的廣闊性,從IPv4向IPv6的過(guò)渡將會(huì)是一個(gè)漫長(zhǎng)的過(guò)程,IPv6翻譯過(guò)渡技術(shù)就是針對(duì)這一重大迫切需求提出的一種高效可行的技術(shù)。在IPv6翻譯過(guò)渡技術(shù)的部署應(yīng)用中擁有功能全面、性能穩(wěn)定的過(guò)渡設(shè)備至關(guān)重要,而對(duì)支持新的過(guò)渡技術(shù)的設(shè)備進(jìn)行一致性測(cè)試,可以在最大程度上保證不同過(guò)渡設(shè)備之間的互聯(lián)互通性。由于IPv6翻譯過(guò)渡技術(shù)處于發(fā)展初期,因此針對(duì)該技術(shù)的一致性測(cè)試同樣屬于新的研究領(lǐng)域,國(guó)內(nèi)外研究機(jī)構(gòu)提出的相關(guān)研究成果較少,設(shè)計(jì)具有自主知識(shí)產(chǎn)權(quán)的IPv6翻譯過(guò)渡技術(shù)一致性測(cè)試系統(tǒng)為翻譯過(guò)渡技術(shù)的發(fā)展提供了強(qiáng)有力的保障,這也是本文選題的意義所在。 本文通過(guò)對(duì)IPv6翻譯過(guò)渡技術(shù)的研究,深入分析了無(wú)狀態(tài)翻譯過(guò)渡技術(shù)SIIT、IVI和有狀態(tài)翻譯過(guò)渡技術(shù)NAT-PT、NAT64在其運(yùn)行環(huán)境下的功能特點(diǎn),結(jié)合一致性測(cè)試標(biāo)準(zhǔn),以模塊化設(shè)計(jì)模型和樹(shù)形管理模型為指導(dǎo)實(shí)現(xiàn)了IPv6翻譯過(guò)渡技術(shù)一致性測(cè)試集,在Linux操作系統(tǒng)下,設(shè)計(jì)實(shí)現(xiàn)了IPv6翻譯過(guò)渡技術(shù)一致性測(cè)試系統(tǒng),并對(duì)四種實(shí)現(xiàn)原理不同的IPv6翻譯過(guò)渡技術(shù)進(jìn)行了一致性測(cè)試實(shí)驗(yàn)。 本文首先分析了研究背景,介紹了現(xiàn)有IPv6翻譯過(guò)渡技術(shù)及IPv6協(xié)議一致性測(cè)試的科研成果,然后對(duì)當(dāng)前三種主要的IPv6過(guò)渡技術(shù)的技術(shù)特點(diǎn)做了詳細(xì)介紹,包括雙協(xié)議棧技術(shù)、隧道過(guò)渡技術(shù)以及IPv6翻譯過(guò)渡技術(shù)。 結(jié)合一致性測(cè)試?yán)碚?參考IPv6協(xié)議一致性測(cè)試模型,提出以模塊化和樹(shù)形模型的獨(dú)特形式設(shè)計(jì)并管理IPv6翻譯過(guò)渡技術(shù)一致性測(cè)試集。按照一致性測(cè)試集的設(shè)計(jì)流程及組織架構(gòu)對(duì)四種IPv6翻譯過(guò)渡技術(shù)的一致性測(cè)試集的具體實(shí)現(xiàn)進(jìn)行了詳細(xì)介紹。 在一致性測(cè)試集結(jié)構(gòu)的基礎(chǔ)上,本文實(shí)現(xiàn)了IPv6翻譯過(guò)渡技術(shù)一致性測(cè)試系統(tǒng)中的三個(gè)關(guān)鍵模塊——編譯器子系統(tǒng)、執(zhí)行器子系統(tǒng)以及界面子系統(tǒng),對(duì)各子系統(tǒng)具體實(shí)現(xiàn)的數(shù)據(jù)結(jié)構(gòu)、算法實(shí)現(xiàn)以及開(kāi)發(fā)過(guò)程中的技術(shù)難點(diǎn)進(jìn)行了詳細(xì)講解。 最后,本文通過(guò)對(duì)四種IPv6翻譯過(guò)渡技術(shù)的實(shí)際測(cè)試來(lái)驗(yàn)證本測(cè)試系統(tǒng)的正確性。 本文研究開(kāi)發(fā)的IPv6翻譯過(guò)渡技術(shù)一致性測(cè)試系統(tǒng)為IPv6翻譯過(guò)渡技術(shù)的實(shí)現(xiàn)提供了一個(gè)標(biāo)準(zhǔn)量化工具,可以有效提高不同技術(shù)實(shí)現(xiàn)之間的互聯(lián)互通性,具有擴(kuò)展性強(qiáng)、不基于協(xié)議棧、功能全面等特點(diǎn),為IPv6翻譯過(guò)渡技術(shù)的推廣部署建立了良好的基礎(chǔ)。
[Abstract]:With the increasing number of Internet users, the requirements for multi-service support, security and mobility of Internet become more and more high. It is urgent to study the next generation Internet based on IPv6. However, due to the complexity of the network environment and the wide coverage of the current IPv4 services, the transition from IPv4 to IPv6 will be a long process. The IPv6 translation transition technology is an efficient and feasible technology aimed at this urgent need. Having a full-featured, stable transition device in the deployment application of IPv6 translation transition technology is critical, and conformance testing of devices that support new transition technologies is essential. The interconnection and interoperability between different transition devices can be guaranteed to the maximum extent. Because the IPv6 translation transition technology is in the early stage of development, the conformance testing of this technology is also a new research field, and the related research results proposed by domestic and foreign research institutions are few. The design of IPv6 translation transition technology conformance testing system with independent intellectual property rights provides a strong guarantee for the development of translation transition technology, which is also the significance of this thesis. Through the study of IPv6 translation transition technology, this paper deeply analyzes the functional characteristics of stateless translation transition technology SIIT,IVI and stateful translation transition technology NAT-PT,NAT64 in its running environment, combining with conformance testing standards. Under the guidance of modular design model and tree management model, the conformance test set of IPv6 translation transition technology is implemented. Under the Linux operating system, the IPv6 translation transition technology conformance test system is designed and implemented. The conformance tests of four IPv6 translation transition techniques with different implementation principles are carried out. This paper first analyzes the research background, introduces the existing IPv6 translation transition technology and the research results of IPv6 protocol conformance testing, and then introduces in detail the technical characteristics of the three main IPv6 transition technologies, including dual protocol stack technology. Tunnel transition technology and IPv6 translation transition technology. Combined with conformance testing theory and referring to IPv6 protocol conformance test model, this paper proposes to design and manage IPv6 translation transition technology conformance test set in the unique form of modularization and tree model. According to the design flow and organizational structure of the conformance test set, the implementation of the conformance test set of four IPv6 translation transition techniques is introduced in detail. Based on the conformance test set structure, three key modules in the conformance test system of IPv6 translation transition technology-compiler subsystem, executive subsystem and interface subsystem are implemented in this paper. The data structure, algorithm realization and technical difficulties in the development process of each subsystem are explained in detail. Finally, the correctness of the test system is verified by the practical testing of four IPv6 translation transition techniques. The conformance testing system of IPv6 translation transition technology developed in this paper provides a standard quantitative tool for the implementation of IPv6 translation transition technology, which can effectively improve the interconnection and interoperability between different technology implementations, and has strong expansibility. It is not based on protocol stack and full function, which establishes a good foundation for the popularization and deployment of IPv6 translation transition technology.
