【摘要】：IPv4已經(jīng)使用30多年，至今仍是現(xiàn)代互聯(lián)網(wǎng)的核心協(xié)議。然而隨著IPv4地址資源日漸枯竭，IPv4的弊端日益明顯，從IPv4過(guò)渡到IPv6成為網(wǎng)絡(luò)發(fā)展的必然趨勢(shì)。隧道技術(shù)是過(guò)渡進(jìn)程中解決兼容性問(wèn)題的主要技術(shù)，在IPv6遷移初期占據(jù)重要地位。網(wǎng)絡(luò)設(shè)備層面的升級(jí)奠定了IPv6商業(yè)部署與推廣的基礎(chǔ)。這就要對(duì)網(wǎng)絡(luò)設(shè)備的過(guò)渡技術(shù)特別是隧道技術(shù)進(jìn)行研究和測(cè)試，檢驗(yàn)其能否完全支持IPv6網(wǎng)絡(luò)互聯(lián)互通。傳統(tǒng)的測(cè)試方式已經(jīng)無(wú)法滿足這些設(shè)備功能日臻完善、版本快速更新的測(cè)試需求。而基于云計(jì)算的測(cè)試方案——云測(cè)試可以提供高效的自動(dòng)化測(cè)試服務(wù)，實(shí)現(xiàn)測(cè)試環(huán)境的統(tǒng)一管理和動(dòng)態(tài)分配，彌補(bǔ)傳統(tǒng)測(cè)試的缺陷。因此在云測(cè)試系統(tǒng)的基礎(chǔ)上，設(shè)計(jì)實(shí)現(xiàn)自動(dòng)化測(cè)試套，對(duì)于IPv6隧道技術(shù)的測(cè)試具有重要意 義。IPv6隧道技術(shù)分為三類：配置隧道（手工隧道、GRE隧道），自動(dòng)隧道（IPv4兼容IPv6自動(dòng)隧道、6to4隧道、ISATAP隧道）和基于MPLS的隧道（6PE技術(shù)）。本文在對(duì)隧道技術(shù)深入研究基礎(chǔ)上，完成以下幾個(gè)方面的內(nèi)容：首先分析了各種隧道技術(shù)的工作原理；其次明確所使用的智能云測(cè)試系統(tǒng)STC（Smart Test Cloud）的功能需求，探討STC的整體架構(gòu)設(shè)計(jì)；然后結(jié)合RFC協(xié)議標(biāo)準(zhǔn)、產(chǎn)品需求以及實(shí)際應(yīng)用，從基本功能測(cè)試、組合測(cè)試、規(guī)格壓力測(cè)試三方面分別設(shè)計(jì)測(cè)試用例，，設(shè)計(jì)時(shí)充分考慮到配置、自動(dòng)隧道和基于MPLS的隧道之間巨大的差異，提出了不同的測(cè)試要點(diǎn)，并采用TCL語(yǔ)言開發(fā)了手工隧道、IPv4兼容IPv6自動(dòng)隧道、GRE隧道、6to4隧道、ISATAP隧道和6PE共六個(gè)模塊的腳本，實(shí)現(xiàn)自動(dòng)化測(cè)試套；最后通過(guò)STC執(zhí)行測(cè)試套得到設(shè)備上隧道技術(shù)的支持情況，結(jié)果表明本文設(shè) 計(jì)的測(cè)試套有效可行。本文介紹的云測(cè)試系統(tǒng)為后續(xù)研究者提供了可借鑒的經(jīng)驗(yàn)，設(shè)計(jì)實(shí)現(xiàn)的測(cè)試套能為網(wǎng)絡(luò)設(shè)備IPv6隧道技術(shù)質(zhì)量的可靠性和穩(wěn)定性提供保證。
[Abstract]:IPv4 has been used for more than 30 years and is still the core protocol of modern Internet. However, the disadvantages of IPv4 are becoming more and more obvious with the depletion of IPv4 address resources. The transition from IPv4 to IPv6 has become an inevitable trend of network development. Tunnel technology is the main technology to solve the compatibility problem in the transition process, which occupies an important position in the early stage of IPv6 migration. The upgrade of network equipment lay the foundation for the commercial deployment and promotion of IPv6. It is necessary to study and test the transition technology of network equipment, especially tunnel technology, and test whether it can support IPv6 network interconnection completely. The traditional testing methods can not meet the needs of these devices. Cloud testing, based on cloud computing, can provide efficient automated testing services, achieve unified management and dynamic allocation of test environments, and make up for the shortcomings of traditional testing. Therefore, based on the cloud test system, the automatic test suite is designed and implemented. There are three types of tunnel techniques for testing IPv6 tunnel technology. IPv6 tunnel technology is divided into three categories: configuration tunnel (manual tunnel / GRE tunnel), automatic tunnel (IPv4 compatible IPv6 automatic tunnel (IPv6) 6to4 tunnel / ISATAP tunnel) and tunnel based on MPLS (6PE technology). Based on the in-depth study of tunnel technology, this paper completes the following aspects: firstly, it analyzes the working principle of various tunnel technologies; secondly, it clarifies the functional requirements of the intelligent cloud test system (STC (Smart Test Cloud), which is used in the tunnel testing system. This paper discusses the overall architecture design of STC, and then designs test cases from three aspects: basic function test, combination test and specification stress test, combining with RFC protocol standard, product requirement and practical application. There are great differences between automatic tunnel and tunnel based on MPLS, different test points are put forward, and six modules script of manual tunnel IPv4 compatible with IPv6 automatic tunnel, IPv6 tunnel 6to4 and 6PE, are developed with TCL language. Finally, the tunnel technology on the equipment is supported by STC execution test suite, and the results show that the test suite designed in this paper is effective and feasible. The cloud test system introduced in this paper provides a reference experience for future researchers. The test suite designed and implemented can guarantee the reliability and stability of the IPv6 tunnel technology quality of network equipment.
