The Research Of Long-Distance Data Network Management System

Unceasing expands along with the long-distance data networkaccommodates, the network scale also day by day expands, the networkcomplexity enhances day by day, the multi- merchants question isextremely prominent. As a result of each kind of network and the lackof equipment unification network management, has brought the verymajor difficulty for the network maintenance. This has had thesynthesis network management system demand, namely will synthesize theexisting independent existence each specialized network systemsynthesis a function to be complete, face the future comprehensivenetwork management system. The comprehensive network management systemcan to the different network which interlocks implement each kind ofmanagement and the control through a network management workstation,thus realizes to the entire net synthesis management, including entirenet function and so on fault analysis and breakdown localization,entire net performance generalized analysis. Like this already isadvantageous for the maintenance, the use, also may enhance thissystem the use factor.This article unifies the current network management the demandcharacteristic, studies the SNMP network management agreement theprinciple of work, produces the long-distance data network synthesismanagement system management system the concrete realization.First, the paper has carried on the analysis in view of the synthesis network management system construction necessity, through had theachievement to the oneself the research and the literature materialcollection reorganization, the analysis has studied the SNMP networkmanagement agreement system structure, the agreement operation and thebasic principle.In this foundation, according to the demand analysis result,in the light of the management object comprehensive, the management functionconsummated, principle and so on user contact surface unification, thepaper proposed the level, the modulation, were easy the LDNMS modelwhich expanded. And in detail described the model 5 levels malfunctions.The paper in view of model in data acquisition level, elaborated basedon the SNMP proxy data acquisition realization method, and carried onthe concrete module to decompose. And in detail elaborated each modulerealization flow and the essential technology.Finally, according to the system model which designed, I have researched and developed a set of long-distance datanetworks synthesis management system management system, and applied Web and the database in LDNMS, it has provided the friendly interactive contact surface for the user, solved during each module to realize theresources sharing question. The system has be in operation in the company.
