【摘要】：實(shí)驗(yàn)作為當(dāng)代工科教育教學(xué)的一個重要環(huán)節(jié),對培養(yǎng)學(xué)生解決實(shí)際問題的能力至關(guān)重要。近幾年來,隨著學(xué)生數(shù)量的增加,學(xué)校的實(shí)驗(yàn)器材已無法滿足學(xué)生的實(shí)驗(yàn)需求。為解決這一問題,基于虛擬化技術(shù)的“虛擬實(shí)驗(yàn)”應(yīng)運(yùn)而生。 虛擬實(shí)驗(yàn)的出現(xiàn)使得學(xué)生能夠不受時間、空間以及傳統(tǒng)的教學(xué)模式的限制,隨時可以登錄進(jìn)入與真實(shí)設(shè)備現(xiàn)場相同的實(shí)驗(yàn)環(huán)境,而且也不用擔(dān)心反復(fù)試驗(yàn)對實(shí)驗(yàn)器材造成的影響。這不僅僅提高了學(xué)生的動手能力,還能夠達(dá)到資源共享的效果,并為學(xué)校節(jié)約了很多高額的設(shè)備投入資金、場地建設(shè)資金以及設(shè)備的日常維護(hù)和管理費(fèi)用。 針對本校計算機(jī)通信網(wǎng)絡(luò)課程的實(shí)驗(yàn)需求,本課題組前期開發(fā)了“遠(yuǎn)程虛擬實(shí)驗(yàn)平臺”并已投入使用。本課題在此基礎(chǔ)上進(jìn)一步研究和探索了一種基于“云概念”的虛擬實(shí)驗(yàn)方法,研究了在云環(huán)境下進(jìn)行虛擬組網(wǎng)的技術(shù),提出了“基于vSphere的虛擬路由管理和分配”方案。旨在解決原虛擬組網(wǎng)系統(tǒng)中存在的“組網(wǎng)拓?fù)浣Y(jié)構(gòu)及實(shí)驗(yàn)步驟固定”的問題,使組網(wǎng)路由器的個數(shù)和實(shí)驗(yàn)步驟可以按需設(shè)置,以進(jìn)一步達(dá)到真實(shí)組網(wǎng)的效果。 本文主要分為三個部分。第一部分：詳細(xì)闡述了虛擬化相關(guān)技術(shù)的概念、技術(shù)方法、結(jié)構(gòu)框架以及國內(nèi)外研究現(xiàn)狀,同時,深入研究了基于虛擬化技術(shù)的云操作系統(tǒng)———vSphere的基本概念、體系結(jié)構(gòu)以及關(guān)鍵技術(shù),為完成基于vSphere的虛擬路由管理和分配系統(tǒng)的設(shè)計打下了基礎(chǔ)；第二部分：在對vSphere云操作系統(tǒng)以及虛擬路由的研究和分析的基礎(chǔ)上,提出并設(shè)計了基于vSphere的虛擬路由管理和分配系統(tǒng)的總體框架,描述了它的執(zhí)行邏輯,并設(shè)計出了基于vSphere的虛擬路由管理和分配系統(tǒng)的系統(tǒng)架構(gòu),本文還詳細(xì)分析了這一系統(tǒng)架構(gòu)；第三部分：在對虛擬實(shí)驗(yàn)平臺以及云操作系統(tǒng)相關(guān)技術(shù)研究的基礎(chǔ)上,搭建了基于vSphere云操作系統(tǒng)的系統(tǒng)環(huán)境,部署實(shí)施了虛擬路由管理和分配系統(tǒng)的資源檢索、管理等模塊。 本文的設(shè)計和研究給虛擬實(shí)驗(yàn)平臺提供了一套新的思路和方法,在現(xiàn)有的“虛擬實(shí)驗(yàn)平臺”的基礎(chǔ)上,通過添加基于vSphere云操作系統(tǒng)的資源管理和分配,實(shí)現(xiàn)了組網(wǎng)路由器的按需分配,使得實(shí)驗(yàn)效果更加真實(shí),用戶只需要選擇合適的路由資源并對路由本身的性能進(jìn)行配置,便可實(shí)現(xiàn)靈活的自由組網(wǎng),從而打破固定的實(shí)驗(yàn)?zāi)Ｊ健?br/>[Abstract]:As an important link in contemporary engineering education, experiment is very important to cultivate students' ability to solve practical problems. In recent years, with the increase of the number of students, the experimental equipment can not meet the needs of the students. In order to solve this problem, virtual experiment based on virtualization technology emerged as the times require. The emergence of virtual experiments allows students to log in to the same experimental environment as real equipment at any time without the limitations of time, space and traditional teaching models. And there is no need to worry about the effects of repeated tests on experimental equipment. This not only improves the students' practical ability, but also can achieve the effect of resource sharing, and saves a lot of high investment funds for the school equipment, site construction funds and the daily maintenance and management costs of the equipment. According to the experiment demand of the computer communication network course in our school, our group developed the "remote virtual experiment platform" and put it into use. On this basis, a virtual experiment method based on "cloud concept" is studied, the technology of virtual networking in cloud environment is studied, and a scheme of "virtual routing management and assignment based on vSphere" is proposed. The purpose of this paper is to solve the problem of "fixed network topology and experimental steps" existing in the original virtual networking system, so that the number of routers and the experimental steps can be set according to needs, so as to further achieve the effect of real networking. This paper is divided into three parts. The first part: the concept of virtualization related technology, technology methods, structure framework and domestic and foreign research status, at the same time, the basic concept of cloud operating system (vSphere) based on virtualization technology is studied in detail. The architecture and key technologies lay the foundation for the design of virtual routing management and allocation system based on vSphere. The second part: based on the research and analysis of vSphere cloud operating system and virtual routing, the general framework of virtual routing management and allocation system based on vSphere is proposed and designed, and its execution logic is described. The system architecture of virtual routing management and allocation system based on vSphere is designed, and the system architecture is analyzed in detail in this paper. The third part: based on the research of virtual experimental platform and cloud operating system technology, the system environment based on vSphere cloud operating system is built, and the resource retrieval and management modules of virtual routing management and allocation system are deployed and implemented. The design and research of this paper provide a new idea and method for the virtual experiment platform. On the basis of the existing virtual experiment platform, the resource management and allocation based on vSphere cloud operating system are added. The network routers can be allocated according to their needs, which makes the experimental results more realistic. Users only need to select the appropriate routing resources and configure the performance of the routing itself, so that flexible free networking can be realized and the fixed experimental mode can be broken.
