【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)過嚴格的測試和驗證。構(gòu)建大規(guī)模的、真實的、可控的試驗平臺不僅是未來互聯(lián)網(wǎng)研究的基礎(chǔ),也是對未來互聯(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)試驗平臺的發(fā)展現(xiàn)狀的基礎(chǔ)上,針對現(xiàn)有試驗平臺在基礎(chǔ)設(shè)施共享、試驗生命周期管理和網(wǎng)絡(luò)可編程性存在的問題,綜合運用云計算、語義網(wǎng)、軟件定義網(wǎng)絡(luò)等先進理論和技術(shù),從體系架構(gòu)、描述語言和可編程虛擬網(wǎng)絡(luò)服務(wù)三個方面研究了未來互聯(lián)網(wǎng)試驗平臺的關(guān)鍵技術(shù),并初步完成了原型實現(xiàn)和應(yīng)用驗證。具體而言,本文的貢獻與創(chuàng)新之處包括如下幾個方面： 1.對國內(nèi)外未來互聯(lián)網(wǎng)試驗平臺進行了廣泛深入調(diào)研,梳理了未來互聯(lián)網(wǎng)試驗平臺的發(fā)展現(xiàn)狀。在調(diào)研分析的基礎(chǔ)上,對試驗平臺進行了系統(tǒng)歸納和分類,總結(jié)了現(xiàn)有試驗平臺存在的問題,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)試驗平臺建設(shè)的發(fā)展趨勢。 2.針對試驗平臺中試驗服務(wù)與試驗資源深度耦合,不同試驗平臺之間資源難以共享的問題,提出并設(shè)計了“試驗即服務(wù)”的試驗平臺概念模型和基于基礎(chǔ)設(shè)施云的技術(shù)架構(gòu)。首先在分析平臺功能、用戶需求和底層設(shè)施特點的基礎(chǔ)上,確定了平臺設(shè)計的架構(gòu)原則。然后借鑒云計算“一切皆服務(wù)”的思想,提出了“試驗即服務(wù)”的概念模型。最后從技術(shù)實現(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)計了其關(guān)鍵組件。 3.針對試驗平臺缺乏統(tǒng)一試驗描述語言,難以實現(xiàn)試驗的描述、組織、實施與回放等試驗生命周期管理的問題,提出并設(shè)計了分層可演進的試驗描述語言和基于試驗描述語言的試驗生命周期管理自動化機制。首先根據(jù)試驗生命周期管理自動化的需求,提出了試驗描述語言的設(shè)計原則。然后利用本體論和Web語義相關(guān)理論,提出并設(shè)計了一種分層可演進的未來互聯(lián)網(wǎng)試驗描述語言框架和實現(xiàn)方案。最后,基于所提出的試驗描述語言框架,提出并設(shè)計了一種試驗生命周期管理自動化機制。 4.針對傳統(tǒng)網(wǎng)絡(luò)試驗平臺難以進行新型網(wǎng)絡(luò)協(xié)議等新技術(shù)驗證的問題,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)計了一種靈活高效的PVN實現(xiàn)機制。首先擴展了現(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),并針對傳統(tǒng)技術(shù)在虛擬網(wǎng)絡(luò)隔離中擴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)隔離機制。 5.根據(jù)本文所提出的系統(tǒng)架構(gòu)、試驗描述語言和可編程虛擬網(wǎng)絡(luò)服務(wù)實現(xiàn)機制,利用現(xiàn)有的云平臺和OpenFlow技術(shù),設(shè)計實現(xiàn)了一個可編程虛擬網(wǎng)絡(luò)試驗平臺原型ProViNet,并進行了系統(tǒng)測試和試驗驗證。
[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.
