(2) network state that network state management module receives from network state describing module describes information After, perform the decomposition of network state and state mapping process, obtain corresponding with this network state or The behavior of multiple network equipments simulation and operation conditions thereof, and the behavior of these network equipments and run shape The corresponding operational order of condition passes to data processing module:
(3) data processing module is carried out at background by the SNMP data having recorded actual device Reason, or the two ways generation SNMP of background data stream is directly generated by the MIB storehouse of this network equipment 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.
