【摘要】：軟件定義網(wǎng)絡(luò)(Software Defined Networking, SDN)是一種新型的網(wǎng)絡(luò)架構(gòu),OpenFlow作為一個符合SDN理念的標(biāo)準(zhǔn)化協(xié)議引起業(yè)界的高度重視。國內(nèi)外廠商相繼研發(fā)推出OpenFlow交換設(shè)備,并在網(wǎng)絡(luò)中試驗(yàn)和應(yīng)用。為了保障設(shè)備質(zhì)量和網(wǎng)絡(luò)有效運(yùn)行,OpenFlow的測試與監(jiān)控技術(shù)的研究急需跟進(jìn)。 論文主要研究OpenFlow的測試與監(jiān)控兩大部分。首先根據(jù)廠商OpenFlow交換機(jī)的實(shí)際測試需求,選取合適的測試工具,研究完善OFTest測試框架,搭建測試環(huán)境,實(shí)際應(yīng)用于測試盛科OpenFlow交換機(jī)實(shí)現(xiàn)的所有功能。之后根據(jù)測試需求說明和一致性實(shí)現(xiàn)聲明等文檔,制定了全部功能的測試計(jì)劃,采用等價類劃分法、邊界值分析法和錯誤推測法等方法,完成了其中部分測試用例的設(shè)計(jì),以及相應(yīng)自動化測試腳本的擴(kuò)展,最終通過運(yùn)行測試,完成了盛科V330OpenFlow交換機(jī)的功能測試,保障了其實(shí)現(xiàn)質(zhì)量。隨后該交換機(jī)通過了業(yè)界知名廠商評估測試,得到客戶較高評價。 在OpenFlow交換機(jī)功能實(shí)現(xiàn)正確的基礎(chǔ)上,以O(shè)penFlow協(xié)議規(guī)范為基礎(chǔ),結(jié)合網(wǎng)絡(luò)流量特征,研究OpenFlow網(wǎng)絡(luò)流量實(shí)時監(jiān)測和控制的方法策略。通過有區(qū)別的流量信息采集的方法,設(shè)計(jì)實(shí)現(xiàn)了對網(wǎng)絡(luò)正常運(yùn)行影響較小的實(shí)時網(wǎng)絡(luò)流量信息監(jiān)測系統(tǒng),包括大象流的實(shí)時流量監(jiān)測和OpenFlow交換機(jī)端口的實(shí)時流量監(jiān)測。最后結(jié)合流量信息,分析研究OpenFlow網(wǎng)絡(luò)的流量優(yōu)化控制策略及其可行性。
[Abstract]:The software defined network (Software Defined Networking, SDN) is a new network architecture. OpenFlow, as a standardized protocol in line with the SDN concept, has attracted great attention in the industry. Domestic and foreign manufacturers have developed and introduced OpenFlow switching equipment, and in the network test and application. In order to ensure the quality of equipment and the effective operation of the network, the research of OpenFlow testing and monitoring technology needs to be followed up. This paper mainly studies two parts of OpenFlow testing and monitoring. Firstly, according to the actual test requirements of the manufacturer OpenFlow switch, we select the appropriate test tools, study and improve the OFTest test framework, build the test environment, and apply it to test all the functions realized by Shengke OpenFlow switch. Then, according to the test requirement description and consistency realization document, the test plan of all functions is worked out, and some of the test cases are designed by using the method of equivalence class partition, boundary value analysis and error prediction. Finally, through running test, the function test of Shengke V330OpenFlow switch is completed, and the quality of its implementation is guaranteed. Subsequently, the switch passed the industry famous manufacturer evaluation test, and received high customer evaluation. On the basis of the correct realization of OpenFlow switch function, based on the OpenFlow protocol specification and the characteristics of network traffic, the method and strategy of real-time monitoring and control of OpenFlow network traffic are studied. A real-time network traffic information monitoring system, which has little influence on the normal operation of the network, is designed and implemented by different methods of traffic information collection, including the real-time traffic monitoring of elephant flow and the real-time traffic monitoring of OpenFlow switch port. Finally, the optimal flow control strategy and its feasibility of OpenFlow network are analyzed and studied with traffic information.
