| In recent years, with the development of mobile Internet, cloud computing and big data services, it has made a big influence to the daily life of people. As network applications emerge in an endless stream, it brings great convenience to users, as the same time, it put forward higher requirements to the network construction and maintenance management, we hope that it should change and robust neatly with need. Due to the limited support of SNMP protocol for network settings, network management system using SNMP implementing the function of network configuration meets problems.SDN implementing data forwarding and control separation provides the possibility to realize the networking configuration management system.The core design of this essay is to realize that the control layer obtaining the underlying network equipment between topological relations to return to management and management system combined with specific business needs by openflow forwarding and control separation structure, form the strategy planning, finally, the scheme is sent to the control layer, configurating the network equipment, and realize the automatic deployment of strategy.This paper firstly discussed the present development situation of network management system,analysised the software defined network, OpenFlow protocol,OF-CONFIG configuration management principle and mechannism in detail;designed and implemented a centralized network management system based on OpenFlow, analysised and elaborated the function of the management system to conduct in detail, combined with the management application layer service requirements,designed service component of application layer and sevice,control agent component of control layer with top-down module design,realized controller calling to the underlying and cyber source through the visual way of network; finally, the prototype system is tested and confirmed to be correct of the pre management system function, and conclued the work. |
