【摘要】：基于OpenFlow協(xié)議的軟件定義網(wǎng)絡(luò)(SDN),相比于當前的TCP/IP網(wǎng)絡(luò)體系結(jié)構(gòu),在靈活性、可擴展性和可管理性方面,更易于滿足快速變化的應(yīng)用需求。SDN技術(shù)的出現(xiàn)帶來了諸多機遇,同時也面臨著更多的挑戰(zhàn),OpenFlow交換機的遠程管理就是其中之一。論文基于OpenFlow交換機管理的技術(shù)規(guī)范,對比傳統(tǒng)的網(wǎng)絡(luò)管理技術(shù),研究OpenFlow網(wǎng)管的關(guān)鍵問題和實現(xiàn)技術(shù)。論文首先基于OF-Config協(xié)議和管理信息YANG模型,重點分析了網(wǎng)管功能和OVSDB操作的對應(yīng)關(guān)系,給出了OpenFlow交換機的遠程管理系統(tǒng)的原型設(shè)計,設(shè)計了管理程序的功能適配方案,擴展定義了YANG信息模型結(jié)構(gòu),包括專用的狀態(tài)容器、邏輯交換機的端口類型和QoS的RPC操作等。其次,論文基于開源軟件Yuma,使用其yangdump程序執(zhí)行YANG模型文件的預(yù)編譯,包括語法語義校驗和服務(wù)器端工具庫SIL文件生成。通過OVSDB對應(yīng)功能調(diào)用,完成了SIL開發(fā),用于對OpenFlow交換機的配置修改與狀態(tài)查詢。最后,論文對遠程管理系統(tǒng)的功能進行了驗證測試。利用XenServer虛擬化環(huán)境建立了測試網(wǎng)絡(luò),針對系統(tǒng)的管理功能需求,設(shè)計了測試用例,并通過相應(yīng)的測試對系統(tǒng)功能進行驗證,包括NETCONF會話的建立、控制器的分配以及交換機端口的配置等。
[Abstract]:Compared with the current TCP / IP network architecture, the software definition network based on OpenFlow protocol brings a lot of opportunities in terms of flexibility, extensibility and manageability. At the same time, facing more challenges, the remote management of OpenFlow switch is one of them. Based on the technical specification of OpenFlow switch management, compared with the traditional network management technology, this paper studies the key issues and implementation techniques of OpenFlow network management. Firstly, based on the OF-Config protocol and the management information model, the corresponding relationship between the network management function and the OVSDB operation is analyzed, and the prototype design of the remote management system of OpenFlow switch is presented, and the functional adaptation scheme of the management program is designed. The extension defines the structure of Yang information model, including special state container, port type of logical switch and RPC operation of QoS. Secondly, based on the open source software Yuma, the paper uses its yangdump program to perform pre-compilation of yen model files, including syntax and semantic verification and server-side tool library sil file generation. Through the OVSDB corresponding function call, the sil development is completed, which is used to modify the configuration and query the status of OpenFlow switch. Finally, the function of remote management system is verified and tested. The test network is established by using Xen Server virtualization environment. The test cases are designed according to the management function requirements of the system, and the system functions are verified by the corresponding tests, including the establishment of the NETCONF session. Allocation of controllers and configuration of switch ports.
