【摘要】：現(xiàn)有的網(wǎng)絡(luò)架構(gòu)已難以滿足未來互聯(lián)網(wǎng)發(fā)展的需求,迫切需要技術(shù)創(chuàng)新來推動(dòng)發(fā)展。但是,任何新技術(shù)在部署和應(yīng)用前,都必須經(jīng)過嚴(yán)格的測(cè)試和驗(yàn)證。構(gòu)建大規(guī)模的、真實(shí)的、可控的試驗(yàn)平臺(tái)不僅是未來互聯(lián)網(wǎng)研究的基礎(chǔ),也是對(duì)未來互聯(lián)網(wǎng)本身探索和研究的一種途徑。 本文在深入調(diào)研未來互聯(lián)網(wǎng)試驗(yàn)平臺(tái)的發(fā)展現(xiàn)狀的基礎(chǔ)上,針對(duì)現(xiàn)有試驗(yàn)平臺(tái)在基礎(chǔ)設(shè)施共享、試驗(yàn)生命周期管理和網(wǎng)絡(luò)可編程性存在的問題,綜合運(yùn)用云計(jì)算、語義網(wǎng)、軟件定義網(wǎng)絡(luò)等先進(jìn)理論和技術(shù),從體系架構(gòu)、描述語言和可編程虛擬網(wǎng)絡(luò)服務(wù)三個(gè)方面研究了未來互聯(lián)網(wǎng)試驗(yàn)平臺(tái)的關(guān)鍵技術(shù),并初步完成了原型實(shí)現(xiàn)和應(yīng)用驗(yàn)證。具體而言,本文的貢獻(xiàn)與創(chuàng)新之處包括如下幾個(gè)方面： 1.對(duì)國內(nèi)外未來互聯(lián)網(wǎng)試驗(yàn)平臺(tái)進(jìn)行了廣泛深入調(diào)研,梳理了未來互聯(lián)網(wǎng)試驗(yàn)平臺(tái)的發(fā)展現(xiàn)狀。在調(diào)研分析的基礎(chǔ)上,對(duì)試驗(yàn)平臺(tái)進(jìn)行了系統(tǒng)歸納和分類,總結(jié)了現(xiàn)有試驗(yàn)平臺(tái)存在的問題,并結(jié)合未來互聯(lián)網(wǎng)技術(shù)的發(fā)展,探討了未來互聯(lián)網(wǎng)試驗(yàn)平臺(tái)建設(shè)的發(fā)展趨勢(shì)。 2.針對(duì)試驗(yàn)平臺(tái)中試驗(yàn)服務(wù)與試驗(yàn)資源深度耦合,不同試驗(yàn)平臺(tái)之間資源難以共享的問題,提出并設(shè)計(jì)了“試驗(yàn)即服務(wù)”的試驗(yàn)平臺(tái)概念模型和基于基礎(chǔ)設(shè)施云的技術(shù)架構(gòu)。首先在分析平臺(tái)功能、用戶需求和底層設(shè)施特點(diǎn)的基礎(chǔ)上,確定了平臺(tái)設(shè)計(jì)的架構(gòu)原則。然后借鑒云計(jì)算“一切皆服務(wù)”的思想,提出了“試驗(yàn)即服務(wù)”的概念模型。最后從技術(shù)實(shí)現(xiàn)的角度,提出了基于基礎(chǔ)設(shè)施云的技術(shù)架構(gòu),并設(shè)計(jì)了其關(guān)鍵組件。 3.針對(duì)試驗(yàn)平臺(tái)缺乏統(tǒng)一試驗(yàn)描述語言,難以實(shí)現(xiàn)試驗(yàn)的描述、組織、實(shí)施與回放等試驗(yàn)生命周期管理的問題,提出并設(shè)計(jì)了分層可演進(jìn)的試驗(yàn)描述語言和基于試驗(yàn)描述語言的試驗(yàn)生命周期管理自動(dòng)化機(jī)制。首先根據(jù)試驗(yàn)生命周期管理自動(dòng)化的需求,提出了試驗(yàn)描述語言的設(shè)計(jì)原則。然后利用本體論和Web語義相關(guān)理論,提出并設(shè)計(jì)了一種分層可演進(jìn)的未來互聯(lián)網(wǎng)試驗(yàn)描述語言框架和實(shí)現(xiàn)方案。最后,基于所提出的試驗(yàn)描述語言框架,提出并設(shè)計(jì)了一種試驗(yàn)生命周期管理自動(dòng)化機(jī)制。 4.針對(duì)傳統(tǒng)網(wǎng)絡(luò)試驗(yàn)平臺(tái)難以進(jìn)行新型網(wǎng)絡(luò)協(xié)議等新技術(shù)驗(yàn)證的問題,提出了可編程虛擬網(wǎng)絡(luò)服務(wù)PVN模型,并采用基于OpenFlow的軟件定義網(wǎng)絡(luò)技術(shù),設(shè)計(jì)了一種靈活高效的PVN實(shí)現(xiàn)機(jī)制。首先擴(kuò)展了現(xiàn)有云服務(wù)的概念,提出了可編程虛擬網(wǎng)絡(luò)服務(wù)的模型。然后按照軟件定義網(wǎng)絡(luò)的邏輯架構(gòu),改進(jìn)了現(xiàn)有基礎(chǔ)設(shè)施云的網(wǎng)絡(luò)架構(gòu)。最后提出并設(shè)計(jì)了基于軟件定義網(wǎng)絡(luò)的可編程虛擬網(wǎng)絡(luò)服務(wù)系統(tǒng),并針對(duì)傳統(tǒng)技術(shù)在虛擬網(wǎng)絡(luò)隔離中擴(kuò)展性和性能上的不足,提出了一種基于MAC的可編程虛擬網(wǎng)絡(luò)隔離機(jī)制。 5.根據(jù)本文所提出的系統(tǒng)架構(gòu)、試驗(yàn)描述語言和可編程虛擬網(wǎng)絡(luò)服務(wù)實(shí)現(xiàn)機(jī)制,利用現(xiàn)有的云平臺(tái)和OpenFlow技術(shù),設(shè)計(jì)實(shí)現(xiàn)了一個(gè)可編程虛擬網(wǎng)絡(luò)試驗(yàn)平臺(tái)原型ProViNet,并進(jìn)行了系統(tǒng)測(cè)試和試驗(yàn)驗(yàn)證。
[Abstract]:The existing network architecture has been difficult to meet the needs of the future development of the Internet, the urgent need to promote the development of technology innovation. However, any new technology in the deployment and application, must go through rigorous testing and validation. The construction of a large-scale, real, controllable test platform is not only the foundation of Internet research in the future, a way but also for the future of the Internet itself to explore and research.
Based on in-depth research of the Internet in the future development of the test platform, according to the existing test platform for sharing in infrastructure, testing life cycle management and network programming problems, the integrated use of cloud computing, semantic web, software defined network advanced theory and technology, from the architecture description language and programming the virtual network service three aspects to research the key technology of future Internet experimental platform, and completed the initial prototype and application verification. Specifically, the contribution and innovation of this paper includes the following several aspects:
1. on the future of the Internet test platform for a wide range of in-depth research, combing the development status of the Internet in the future test platform. Based on the analysis of the investigation of the experimental platform were summarized and classified, summarized the existing problems of the test platform, combined with the future development of Internet technology, discusses the future development trend of the Internet the test platform construction.
2. in depth test platform test and service test resources coupled problems to share resources between different test platform is proposed and designed the test platform model test as a service and technical architecture of cloud based infrastructure. First in the analysis of the function of the platform, the basic characteristics of the user demand and the underlying infrastructure, the the architecture of platform design principles. Then from the cloud computing "all services" thought, put forward the concept of "service model test". Finally, from the view of technique, put forward the technical infrastructure of cloud based architecture, and the design of its key components.
3. according to the test platform of the lack of unified test description language, it is difficult to achieve the test description, organization, implementation and playback test life cycle management problems, proposed and designed the test evolution hierarchical description language and description language based on the experimental test of life cycle management automation mechanism. Based on the experimental life cycle management automation needs, put forward the tests described the design principle of language. Then using ontology and semantic Web theory, and put forward the future of the Internet test a hierarchical evolutionary design description language framework and implementation scheme. Finally, the proposed test description language based on the framework, we propose and design a test automation lifecycle management mechanism.
4. the traditional network test platform to verify the new network protocols such as the problems of the new technology, proposed a programmable virtual network service PVN model, and the use of software defined network technology based on OpenFlow, designed a flexible and efficient mechanism. Firstly, PVN extended the concept of the existing cloud services, puts forward a programmable virtual network service model. Then according to the logical structure of software defined network, improve the existing infrastructure of the cloud network architecture. Finally, proposed and designed the software defined network programmable virtual network service system based on the traditional technology, and lack of scalability and performance in virtual isolation network, proposes a virtual programmable the network isolation mechanism based on MAC.
5. according to the system architecture proposed by this paper, test description language and programmable virtual network service realization mechanism, using the existing cloud platform and OpenFlow technology, the design and implementation of a programmable virtual network experiment platform prototype ProViNet, and the system testing and experiment.
