【摘要】：與IPv4協(xié)議相比，IPv6協(xié)議具有眾多無可比擬的優(yōu)點。下一代因特網(wǎng)（NGI）和下一代網(wǎng)絡（NGN）采用IPv6協(xié)議已經(jīng)成為業(yè)界的共識。由于IPv4協(xié)議和IPv6協(xié)議互不兼容和一些網(wǎng)絡應用上原因，影響了IPv6過渡的進程，迫切需要進行IPv6過渡關(guān)鍵技術(shù)問題的研究，尋找合適的技術(shù)途徑和實現(xiàn)方法，盡早解決IPv6過渡過程中的諸多問題。 本文首先研究了IPv6過渡的相關(guān)技術(shù)，詳細分析了三種過渡技術(shù)的工作原理；接著深入研究了ISATAP隧道技術(shù)和IVI翻譯技術(shù)。在此基礎上，新設計了ISATAP雙棧系統(tǒng)結(jié)構(gòu)的整體框架，并對ISATAP隧道的功能模塊及其實現(xiàn)函數(shù)進行了設計和實現(xiàn)；然后設計了IVI翻譯網(wǎng)關(guān)的整體框架，，并對IVI翻譯網(wǎng)關(guān)的功能模塊及其實現(xiàn)函數(shù)進行了設計和實現(xiàn)；最后通過實驗對ISATAP隧道和IVI翻譯網(wǎng)關(guān)進行了測試和分析。 本文開展的工作主要有以下幾個方面： （1）研究了IPv4的局限性，并對IPv6的產(chǎn)生和優(yōu)勢、IPv6協(xié)議的技術(shù)特點進行了深入研究；重點對三種過渡技術(shù)的工作原理進行了詳細分析，包括雙棧技術(shù)、隧道技術(shù)和翻譯技術(shù)。 （2）深入研究了ISATAP隧道技術(shù)，包括ISATAP地址格式、ISATAP工作原理和ISATAP鄰居發(fā)現(xiàn)機制；深入研究了IVI翻譯技術(shù)，包括IVI地址格式、IVI路由和IVI工作原理。 （3）設計了新的ISATAP雙棧系統(tǒng)結(jié)構(gòu)的整體框架，該ISATAP雙棧系統(tǒng)增加了三個ISATAP隧道功能模塊，即ISATAP數(shù)據(jù)報接收模塊、ISATAP數(shù)據(jù)報發(fā)送模塊和ISATAP數(shù)據(jù)報處理模塊。 （4）詳細設計和編程實現(xiàn)了ISATAP隧道的功能模塊及其函數(shù)，其中ISATAP數(shù)據(jù)報接收模塊負責對收到的數(shù)據(jù)報進行解析和處理，ISATAP數(shù)據(jù)報發(fā)送模塊負責對需要發(fā)送的數(shù)據(jù)報進行解析和處理，ISATAP數(shù)據(jù)報處理模塊負責對數(shù)據(jù)報進行封裝和解封。 （5）設計了新的IVI翻譯網(wǎng)關(guān)的整體框架，該IVI翻譯網(wǎng)關(guān)主要由四個功能模塊組成，即IVI系統(tǒng)控制模塊、IVI DNS模塊、IVI地址翻譯模塊和IVI協(xié)議翻譯模塊。 （6）詳細設計和編程實現(xiàn)了IVI翻譯網(wǎng)關(guān)的功能模塊及其實現(xiàn)函數(shù)，其中IVI系統(tǒng)控制模塊負責整個IVI翻譯網(wǎng)關(guān)系統(tǒng)的控制，IVI DNS模塊負責IPv4網(wǎng)絡和IPv6網(wǎng)絡之間域名解析的翻譯，IVI地址翻譯模塊負責數(shù)據(jù)報的IPv4地址和IPv6地址之間的翻譯，IVI協(xié)議翻譯模塊負責數(shù)據(jù)報的IPv4協(xié)議和IPv6協(xié)議之間的翻譯。 目前，諸多IPv6過渡技術(shù)尚未完全成熟，對ISATAP隧道和IVI網(wǎng)關(guān)整體框架設計、功能模塊、實現(xiàn)函數(shù)的設計等有關(guān)的文獻資料比較少。本文以ISATAP隧道技術(shù)和IVI翻譯技術(shù)為基礎，新設計了ISATAP隧道和IVI網(wǎng)關(guān)的整體框架，并詳細設計了ISATAP隧道和IVI網(wǎng)關(guān)的每一個功能模塊，設計和編寫出新的用于ISATAP隧道和IVI翻譯網(wǎng)關(guān)的多個功能模塊函數(shù)。所研究的內(nèi)容均屬于IPv6過渡中的關(guān)鍵技術(shù)問題。 本文設計與實現(xiàn)的ISATAP隧道和IVI網(wǎng)關(guān)是切實可行的，可以有效地解決IPv4/IPv6過渡時期IPv4網(wǎng)絡和IPv6網(wǎng)絡的通信問題，對今后IPv4/IPv6過渡時期中IPv6過渡技術(shù)關(guān)鍵問題的研究具有一定的應用和參考價值。
[Abstract]:Compared with the IPv4 protocol, the IPv6 protocol has many advantages. There is nothing comparable to this next generation Internet (NGI) and next generation network (NGN) using IPv6 protocol has become the consensus of the industry. Due to incompatible IPv4 protocol and IPv6 protocol and network application, the influence of IPv6 transition process, the urgent need to study the key technical problems of IPv6 transition, looking for a proper way of technology and methods of implementation, as soon as possible to solve the many problems of IPv6 in the process of transition.
This paper firstly studies the related technology of the IPv6 transition, a detailed analysis of the working principle of the three kinds of transition technology; then research the ISATAP tunnel technology and IVI technology. Based on this, the new design of the overall framework of the ISATAP dual stack system structure, and the ISATAP tunnel function module and its realization function is designed and to achieve; then design the overall framework of the IVI translation gateway, and function module of the IVI translation gateway and its functions are designed and realized; through the experiment of ISATAP tunnel and IVI translation gateway were tested and analyzed.
This work mainly in the following aspects:
(1) studied the limitations of IPv4, and produce and advantage of IPv6 technology, the characteristic of IPv6 protocol is studied; the working principle focuses on three kinds of transition technology are analyzed, including dual stack technology, tunnel technology and translation technology.
(2) in-depth study of ISATAP tunnel technology, including the ISATAP address format, the working principle of ISATAP and ISATAP neighbor discovery mechanism; research of IVI translation technology, including the IVI address format, IVI routing and IVI working principle.
(3) design the overall framework of the new ISATAP dual stack system structure, the ISATAP dual stack system adds three ISATAP tunnel function modules, namely ISATAP datagram receiving module, ISATAP data transmission module and ISATAP data processing module.
(4) the detailed design and programming of the function module and function of the ISATAP tunnel, the ISATAP datagram receiving module is responsible for parsing and processing the received data, ISATAP data transmission module is responsible for parsing and processing of the data to be sent, ISATAP datagram processing module is responsible for the encapsulation and decapsulation of datagram.
(5) the design of the overall framework of the new IVI translation gateway, the IVI translation gateway is composed of four functional modules, namely the IVI system IVI control module, DNS module, IVI module and IVI address translation protocol translation module.
(6) the detailed design and programming of the function module of IVI translation gateway and its implementation function, the control system IVI control module is responsible for the entire IVI translation gateway system, IVI DNS module between IPv4 network and IPv6 network domain name translation between IVI address translation module is responsible for the data reported by the IPv4 address and IPv6 address translation IVI, protocol translation module is responsible for the data reported by the IPv4 protocol and IPv6 protocol.
At present, many of the IPv6 transition has not yet fully mature technology, to design the overall framework of ISATAP tunnel and IVI gateway function module, realize the function design of the related literature is relatively small. This paper is based on ISATAP tunnel technology and IVI technology, a new design of the overall framework of the ISATAP tunnel and the IVI gateway, and the detailed design of each a module of ISATAP tunnel and IVI gateway, the design and preparation of a new functional module for multiple function ISATAP tunnel and IVI translation gateway. The research contents are the key technical problems of IPv6 in transition.
In this paper, the design and implementation of the ISATAP tunnel and IVI gateway is feasible, can effectively solve the problem of communication during the transition period of IPv4/IPv6 IPv4 network and IPv6 network, research on IPv6 IPv4/IPv6 in the future during the transition period of transition in the key technical problems has certain application and reference value.
