Background data stream；Again by data adaptation unit according to the equipment adaptation file imported, to wherein SNMP data
Modify and adaptive, then the SNMP data after adaptation are submitted to data readback module；
(4) data readback module is supplied to network management platform the SNMP data stream of network equipment, enters
The real-time playback of row data, presents various analog network state, includes it for network management platform
The various tests that fault management, three functions of configuration management and performance management are corresponding；
(5) graphical interface of user of network state describing module shows every description of present day analog network state
Curve and parameter.
Network state analogy method the most according to claim 6, it is characterised in that: described step (3)
In, actual device the operation of the SNMP data genaration background data stream recorded includes following content:
After user starts a network analog device, select the SNMP number of the most stored real network device
According to, and intercept set the time period data as benchmark, be circulated broadcasting, show this network equipment simultaneously
Basic status parameter；If user wants to stop the broadcasting of this background data stream, then terminate circulation；If user
Want to continually look for the data of other time period, with different behaviors and the operation conditions thereof of analog network device, then
Repeat original operation: on the basis of intercepting the data of this time period, be circulated broadcasting, show now net simultaneously
The basic status parameter of network device；
Directly generated the operation of background data stream by the MIB storehouse of this network equipment and include following content:
Because of the emphasis of analog network state procedure, be realize the network equipment after network state is decomposed behavior and
Its operation conditions, namely amendment background data stream, to present the corresponding operating of network equipment；Therefore first play back
SNMP data, further according to the device configuration file imported, are performed essence by SNMP background data stream smoothly
Really to the amendment of each MIB data, amended SNMP data are exactly the row that the simulation of this network equipment is new
For and the data stream of operation conditions, for network management platform, this data stream is carried out real-time playback, carries out
The test of the various emulation mode of network equipment and emulation.
