【摘要】：軟件定義網(wǎng)絡(luò)(SDN,Software Defined Networking)是一種新型網(wǎng)絡(luò)架構(gòu),它最重要的特征體現(xiàn)在控制層和數(shù)據(jù)層分開,且采用集中控制而非傳統(tǒng)的分布式控制方式及開放的可編程接口,這些特性使得網(wǎng)絡(luò)變得更具有可編程能力,網(wǎng)絡(luò)靈活性得到增強。雖然軟件定義網(wǎng)絡(luò)的出現(xiàn)不是專門為了解決網(wǎng)絡(luò)虛擬化問題,但是SDN推動了網(wǎng)絡(luò)標準化進程,帶給網(wǎng)絡(luò)極大靈活性,給網(wǎng)絡(luò)虛擬化的發(fā)展增加了新的思路和方向。以下為本論文主要的研究內(nèi)容:第一,對SDN架構(gòu)、Open Flow技術(shù)進行深入研究,以及對OpenStack云平臺及其Neutron組件學(xué)習(xí),試圖將SDN和OpenFlow技術(shù)應(yīng)用于云計算,并研究將SDN控制器和OpenStack整合在一起的虛擬網(wǎng)絡(luò)系統(tǒng)的方案。第二,通過對當前市場上的SDN控制器和交換機了解和比較,選取了開源控制器OpenDaylight及Open vSwitch來搭建軟件定義網(wǎng)絡(luò),并研究使用Open Stack網(wǎng)絡(luò)相關(guān)組件實現(xiàn)與OpenDaylight控制器的融合;并對虛擬系統(tǒng)設(shè)計了相關(guān)網(wǎng)絡(luò)網(wǎng)絡(luò)配置及路徑算法改進,初步實現(xiàn)了虛擬系統(tǒng)。第三,為了增強虛擬系統(tǒng)功能,同時研究了云系統(tǒng)和SDN控制器高可用性方案,來提高網(wǎng)絡(luò)可用性。此外還設(shè)計了兩種監(jiān)測方案,并實現(xiàn)了基于Open Flow協(xié)議的網(wǎng)絡(luò)監(jiān)測模塊,增強對虛擬網(wǎng)絡(luò)系統(tǒng)網(wǎng)絡(luò)監(jiān)控,幫助了解虛擬系統(tǒng)網(wǎng)絡(luò)狀態(tài)。第四,本論文對基于Open Flow協(xié)議來實現(xiàn)對SDN網(wǎng)絡(luò)相關(guān)狀態(tài)測試方法進行設(shè)計,充分發(fā)揮SDN自身特性。最后,對虛擬系統(tǒng)并進行了相關(guān)測試,并對網(wǎng)絡(luò)監(jiān)測模塊進行實驗驗證,說明該方案是可行的。
[Abstract]:SDN (Software Defined networking) is a new network architecture. Its most important feature is that the control layer is separated from the data layer, and the centralized control is used instead of the traditional distributed control mode and the open programmable interface. These features make the network more programmable and more flexible. Although the emergence of software-defined network is not designed to solve the problem of network virtualization, SDN promotes the process of network standardization, brings great flexibility to the network, and adds new ideas and directions to the development of network virtualization. The following are the main contents of this thesis: first, the SDN architecture Open Flow technology is deeply studied, and the OpenStack cloud platform and its Neutron components are studied to try to apply SDN and OpenFlow technology to cloud computing. The scheme of virtual network system which integrates SDN controller and OpenStack is studied. Secondly, the open source controller OpenDaylight and Open vSwitch are selected to build the software definition network by comparing the SDN controller and the switch in the current market, and the integration of Open Stack network components with OpenDaylight controller is studied. The related network configuration and path algorithm improvement are designed for the virtual system, and the virtual system is preliminarily realized. Thirdly, in order to enhance the function of virtual system, the high availability scheme of cloud system and SDN controller is studied to improve the availability of network. In addition, two monitoring schemes are designed, and the network monitoring module based on Open Flow protocol is implemented to enhance the network monitoring of virtual network system and help to understand the network status of virtual system. Fourthly, based on Open Flow protocol, this paper designs the SDN network related state test method, and gives full play to the characteristics of SDN itself. Finally, the virtual system is tested and the network monitoring module is tested, which shows that the scheme is feasible.
