| With the rapid development of cloud computing,the scale of cloud data center has become increasingly to enormous size.The traditional network architecture have many shortcomings,the requirements of DC for network can't be met,so a new technology is need to solve the problem.A new popular technology-SDN was researched by the academia,SDN is shifting from academic phase to applied phase now.Derived from a part of the cooperation SDN project with a well-known communication enterprise,a layer3 network management system based on OpenDaylight SDN controller has be developed and researched,applicable primarily to DC network environment.Aimed at decreasing the cost of deployment and maintenance for network and promoting the efficiency of network management.Layer3 Network Management System is an App of OpenDaylight platform,based B/S mode,Java OSGI technology and web technology.L3 network topology visualization,network configuration and network monitoring are implemented.According to the software engineering processes,demand analyses of the system were processed firstly,and some requirements are listed.Secondly,combined with the technical characteristics of OpenDaylight platform,system architecture design scheme is proposed,some module is implemented include web UI,topology management,device configuration and monitoring,yang model design.Finally,test Environment was set up and the function test was elaborated.The system had been used in a real DC network environment.Practice has proven that it is running good and implemented layer3 network management functions effectively. |
