Design And Implementation Of The SNMP Networks Management Agent Of DaTang Switch

DaTang telecom resolve multi management interface and multi edition concomitant problem of management system,improve between complexity and managed device compatibility of management system.DaTang telecom develop uniform network management system.SNMP network management agent is importantly component part of uniform network management system,and it take on important role.Agent is a kind of software module lying in managed network devices,which can access their run-time status,device characteristics,equipment capability,system configure and interrelated information.Network management agent is a middle interface of response action and implement management action between its host device and network management software.nowadays,famous company have developed a number of network management overseas.They not only adopt non-opening disposal mode but also implemented MIB are fixed,so their inner structure and disposal flow are special,agent representation is static and difficult to extending managed object scope.Firstly,this thesis bring forward important meaning of network management on the,basis of DaTang telecom requirement,introduce foreign several network management agent produce specialty.Secondly,it analyze basic model framework, information standard and protocol criterion of SNMP network management.Finally, we put forward the description of design idea and realization method about difficulty to extending and worse currency of current network management agent.Several modules of agent are self-existent,strongly expand,so avoid iteration exploitation.
