As shown in fig. 1, the communication device network management system includes three components: communication equipment, communication equipment network management software (network management software for short) and a management protocol (protocol for short). Network management software manages a large number of various types of communication devices through management protocols.

Therefore, in a commissioning environment, simulation software is used to simulate large-scale, multiple types of real communication devices. The information interaction process of the simulation environment can be as shown in fig. 2, and includes: firstly, network management software sends a request to simulation software; secondly, a request message processing module of the simulation software analyzes request data from the request message; thirdly, the data simulation module simulates response data according to the request data; and the four response message processing modules assemble the response data into response messages and send the response messages to the network management software.

Step 302: when the request data has corresponding preset response data, sending the preset response data to the network pipe end; when the request data does not have corresponding preset response data, the request data is sent to preset communication equipment, and equipment response data returned by the preset communication equipment is sent to the network pipe end;
here, the preset response data, the device response data, and other response data may be packaged by the emulation software and sent to the network pipe end in the form of a response message. The preset response data can be preset at the appointed position of the simulation equipment or the network management equipment and other equipment; corresponding preset response data can be set by adopting a static configuration mode aiming at different request data; the preset response data is used for simulating the response condition of the communication equipment after receiving the request data; the network management terminal can be network management software or network management equipment where the network management software is located;
after receiving the request data, the simulation device can search preset response data corresponding to the request data at a specified position;
if the preset response data corresponding to the request data is found, directly returning the preset response data to the network management software as final simulation response data;
if the preset response data corresponding to the request data are not found, forwarding the request data to preset communication equipment; the preset communication equipment is real communication equipment, a communication link can be established with network management equipment or simulation equipment in a connection mode such as a network, and the request data can be sent to the preset communication equipment through the communication link; different types of preset communication equipment can be set according to the types of the request data which possibly occur so as to meet the requirements of different types of the request data;
the preset communication equipment receives the request data and returns real equipment response data to the simulation software, and the simulation software returns the equipment response data serving as final simulation response data to the network management software; thereby completing the simulation; in this way, by returning the response data of the real communication device, the actual situation is truly simulated.
Further, when first identification information in the request data is consistent with second identification information of the preset response data, determining that the request data corresponds to the preset response data;
here, the first identification information and the second identification information may be identification information such as OID in SNMP or an element tag of XML in NetConf; the different identification information corresponds to different response data;
when static configuration is performed, the preset response data and the second identification information thereof can be stored in a file or other storage media of static configuration simulation data; when the request data is received, the first identification information in the request data can be extracted, the first identification information and the second identification information are compared, and if the first identification information and the second identification information are consistent, the request data and the preset response data are determined to be consistent.
Further, the equipment response data is determined as preset response data corresponding to the request data;
here, after receiving the device response data, the device response data may be stored as preset response data corresponding to the subsequent same request data; and when the request data is received again subsequently, the equipment response data can be directly returned to the network management software. The device response data can be saved to a file or other storage medium of static configuration simulation data; the process of storing the equipment response data can be carried out before or after the equipment response data is sent to the network management software.
Further, recording the response time of the preset communication equipment after receiving the request data, and determining the response time as the delay time for responding to the request data;
specifically, a time point of sending the request data to the preset communication device and a time point of receiving device response data returned by the preset communication device may be recorded, so as to determine a response time of the preset communication device;
the device response data and corresponding response time may be saved to a file or other storage medium of static configuration simulation data; when request data corresponding to the equipment response data appear subsequently, the simulation software reads the equipment response data and the corresponding response time at the same time, delays the time according to the response time and then returns the equipment response data; therefore, response data and response delay of the real communication equipment can be simulated, and the time situation is simulated more truly.
In practical application, the specific implementation steps of the communication device simulation method may be as shown in fig. 4, and include:
step 401: receiving request data; receiving request data sent by network management software by simulation software;
step 402: searching response data corresponding to the request data in the statically configured simulation data according to the identification information of the request data;
step 403: if the response data corresponding to the request data is found, executing step 407, otherwise executing step 404;
step 404: forwarding the request data to the real communication equipment, and timing the response time of the real communication equipment;
step 405: receiving response data sent by real communication equipment and finishing timing response time of the real communication equipment;
step 406: adding the mapping of the request data identification information and the received response data of the real communication equipment into the static configuration, and simultaneously adding the response time of the real communication equipment into the static configuration;
the response time is used for delaying and then sending corresponding response data when the same request data is received subsequently; thus, real communication equipment can be simulated really;
step 407: and returning the response data to the network management software.
