Network System Based On Snmp Protocol. Military Networks, The Design And Realization

Along with fly of the calculator technique and the world information-based construction soon development,the network have already get into people work, study and life of square aspect noodles,network application gradually universality.Current,new technique,new the equipments pile up one after another,in the network connect into the amount of information infrastructure continuously increment,network equipments numerous,server the manufacturer be each difference,add of virus and network attack rampant,network interception problem severity,network equipments the region across an one degree great etc.problem and make network management difficulty day by day enlarge.The our army is aggressive to respond to central call,strongly promote science and technology to train soldiers,always persistence science and technology strong soldier of principle,in the high technology and information-based construction aspect devotion huge energy,network usage in the troops already occupy very big of specific weight.Currently,the network of troops big part is many class network.Include a military district class network,soldier class network,each division class network among them,of all levels network,carry on a conjunction through the soldier net fiber optic special line.The big part adoption of the calculator in the network the operate system including windows,unix/linux etc.,and include a lot of decisive of application server,the data information in the network all belong to inside soldier secret information,if bad management,once reveal or drive break, will bring whole army can't estimate of loss and influence.Because the our army be information-based construction start night,the technique be opposite to fall behind,in the management loophole Pin,lack independence of the calculator network be soft,hardware core technique,calculator network of management software,such as net pass software etc.mostly dependence import.These software all existence a great deal of of safety loophole,easiest leave built-in virus,recessiveness passage...etc,concealed suffer from,at network top circulate,existence very big of safety concealed suffer from.This make troops calculator network of safety the function consumedly lower,the network be placed in to burglarize to listen to,interference,surveillance with cheat etc.variety safety threat medium,network safety appearance extremely weak of.Troops network manager urgent demand a practical network management the system come to help them solid hour control the appearance of network,monitor network break down and excellent turn network structure,with maintenance network of normal stability circulate.Is this,independence design a set of be suitable for application,safety Gao,tailor of net tube the system seem to be is necessity.This text is from the network management first face of problem and development commence,introduction network management of system structure and management function area,analysis comparison each network management technique,choice network management terrace of agreement foundation-simple the network manage agreement SNMP and Be a network management terrace development of agreement foundation,thorough research SNMP principle,from the SNMP of development,SNMP allocation and communication,MIB database,SMI, agreement data unit PDU,arrive the WINDOWS descend SNMP application of development,end pass Virsul C++under the WINDOWS environment realization according to the network for turn of the SNMP mold piece management system.This stationery has very strong adaptability with expand sex.The system basic realization general network management need of main function,include circuit appearance surveillance,discharge test and the Tuo rush toward to discover etc..
