[0035] A network data packet is simulated by the first simulation submodule, the second simulation submodule and the third simulation submodule, and is sent to the network device to be tested through the first network card. The data packet is returned after passing through the network device to be tested, and the network data packet from the network device to be tested is received through the second network card. Application data is obtained by parsing the received network data packet, and the application data is analyzed by the analysis module. The test result of the network device to be tested can be obtained, and the real traffic scenario in the network can be fully simulated, making the simulation of network traffic in reality more flexible. The network device is tested by using the simulation result, and the real operation status of the network device in a complex network environment can be fully and effectively verified.

[0044] The scenario association rules include application layer protocols with a preset sequence relationship, time parameters between adjacent application layer protocols, and values of various simulation parameters. The application layer protocols carry application data, and the application layer protocols include DNS protocol, HTTP protocol, and FTP protocol.
[0045] The correspondence between the scenario identifier and the scenario association rule is pre-stored so as to obtain the corresponding scenario association rule according to the scenario identifier. The scenario association rule corresponding to the scenario identifier is used to define the real traffic scenario corresponding to the scenario identifier.

[0054] By simulating network data packets through the first simulation submodule, the second simulation submodule, and the third simulation submodule, the real traffic scenarios in the network can be fully simulated, making the simulation of actual network traffic more flexible, and being able to comprehensively and effectively verify the actual status of network equipment running in a complex network environment.
[0055] The simulation parameters include: number of concurrent connections, number of new connections per second, number of packets per second, traffic and application. The scenario association rules that can meet the target values of the simulation parameters include: the scenario association rules that the sum of the values of the corresponding simulation parameters is not less than the target value of the simulation parameters.
[0056] By continuously increasing the number of concurrent simulations of scenario association rules, real-time values of various simulation parameters are obtained, thereby obtaining scenario association rules that can meet the target values of various simulation parameters, and realizing real traffic scenario simulation in which a large number of clients download the installation program at the same time.
[0057] In summary, the scenario simulation requirements are received through the first receiving module, the acquisition module is used to obtain the scenario association rules that have a corresponding relationship with the scenario identifier and can meet the target values of each simulation parameter, and the network data packet is simulated by the first simulation sub-module, the second simulation sub-module, and the third simulation sub-module in accordance with the preset sequence relationship. The first network card sends the network data packet to the network device to be tested through the sending module, and returns after passing through the network device to be tested. The second network card receives the network data packet from the network device to be tested through the second receiving module, and the received network data packet is parsed by the parsing module to obtain application data, and the application data is analyzed by the analysis module to obtain the test result of the network device to be tested.
