【摘要】：隨著信息技術(shù)的發(fā)展,現(xiàn)代網(wǎng)絡(luò)管理對(duì)于提高網(wǎng)絡(luò)單元利用率、故障定位和排查技術(shù)提出了更高的要求來確保網(wǎng)絡(luò)的正常運(yùn)行、網(wǎng)絡(luò)優(yōu)化、安全保障和服務(wù)質(zhì)量。SDN(Software Defined Networking,軟件定義網(wǎng)絡(luò))作為新興的網(wǎng)絡(luò)技術(shù),給網(wǎng)絡(luò)管理技術(shù)的發(fā)展帶來了新的機(jī)遇和挑戰(zhàn)。SDN將數(shù)據(jù)轉(zhuǎn)發(fā)和控制相分離,由軟件驅(qū)動(dòng)的中央控制結(jié)點(diǎn)來自動(dòng)化控制整個(gè)網(wǎng)絡(luò)。但目前基于SDN技術(shù)的網(wǎng)絡(luò)管理存在的問題是,SDN交換機(jī)缺乏標(biāo)準(zhǔn)網(wǎng)絡(luò)管理協(xié)議,如何管理融合了SDN平臺(tái)的網(wǎng)絡(luò)已成為網(wǎng)絡(luò)管理領(lǐng)域的研究和應(yīng)用熱點(diǎn)。 本文從分析基于SDN技術(shù)的網(wǎng)絡(luò)故障管理所面對(duì)問題出發(fā),提出采用傳統(tǒng)的SNMP網(wǎng)管協(xié)議和SDN RPC接口技術(shù)結(jié)合的方法,對(duì)融合了SDN平臺(tái)的網(wǎng)絡(luò)故障進(jìn)行管理。通過分析系統(tǒng)需求,將該系統(tǒng)拆分成登錄管理、拓?fù)涔芾�、故障管理、SDN管理、數(shù)據(jù)管理模塊五個(gè)部分。登錄管理模塊實(shí)現(xiàn)了用戶操作權(quán)限的管理。拓?fù)涔芾砟K實(shí)現(xiàn)了拓?fù)浒l(fā)現(xiàn)算法,完成對(duì)網(wǎng)絡(luò)中設(shè)備的發(fā)現(xiàn)。故障管理模塊通過SNMP方式對(duì)傳統(tǒng)網(wǎng)絡(luò)設(shè)備進(jìn)行故障管理,采用SDN RPC接口與OVSDB結(jié)合的方式對(duì)SDN交換機(jī)設(shè)備進(jìn)行故障管理。SDN管理模塊通過開源的OpenFlow插件對(duì)SDN交換機(jī)設(shè)備中流的故障信息進(jìn)行管理。數(shù)據(jù)管理模塊完成了對(duì)拓?fù)鋽?shù)據(jù)及故障數(shù)據(jù)的管理。作者獨(dú)立完成了該系統(tǒng)的登錄管理、拓?fù)涔芾�、故障管理和SDN管理模塊的開發(fā)工作。 本文探索了目前研究和應(yīng)用的熱點(diǎn)SDN技術(shù)及其在網(wǎng)絡(luò)管理系統(tǒng)中的應(yīng)用,在實(shí)驗(yàn)室SDN平臺(tái)上實(shí)現(xiàn)了網(wǎng)絡(luò)故障管理原型系統(tǒng),對(duì)SDN網(wǎng)絡(luò)管理接口的實(shí)現(xiàn)進(jìn)行了有益的嘗試,為進(jìn)一步的工程應(yīng)用實(shí)踐奠定了基礎(chǔ)。經(jīng)過測(cè)試系統(tǒng)在實(shí)驗(yàn)室已成功運(yùn)行。
[Abstract]:With the development of information technology, modern network management has put forward higher requirements to improve the utilization of network units, fault location and troubleshooting technology to ensure the normal operation of the network, network optimization, As a new network technology, it brings new opportunities and challenges to the development of network management technology. SDN separates data forwarding and control. A central control node driven by software automates the entire network. However, the problem of network management based on SDN technology is the lack of standard network management protocol. How to manage the network integrated with SDN platform has become a research and application hotspot in the field of network management. Based on the analysis of the problems in network fault management based on SDN technology, this paper proposes a method of combining the traditional SNMP network management protocol and SDN RPC interface technology to manage the network fault which integrates the SDN platform. By analyzing the requirements of the system, the system is divided into five parts: login management, topology management, fault management SDN management and data management module. The login management module realizes the management of user operation rights. The topology management module realizes the topology discovery algorithm and realizes the discovery of the devices in the network. The fault management module manages the fault of the traditional network equipment by SNMP. The SDN RPC interface and OVSDB are used to manage the fault information of the SDN switch devices through the open source OpenFlow plug-in. Data management module completes the management of topology data and fault data. The author has independently completed the development of login management, topology management, fault management and SDN management module. This paper explores the current research and application of the hot SDN technology and its application in the network management system, realizes the prototype system of network fault management on the laboratory SDN platform, and makes a beneficial attempt to realize the SDN network management interface. It lays a foundation for further engineering practice. The tested system has been successfully run in the laboratory.
