Description

Technical Field

[0001] This invention relates to network scheme verification technology, and more particularly to an automated network scheme verification method based on simulation training equipment. Background Technology

[0002] Currently, there are generally two common solutions for communication network training systems. The first is to use pure software simulation to simulate the communication network, relying on computers to achieve network setup training and equipment operation training. This mode can effectively save training costs and achieve large-scale network scenario training. The second is to build a basic environment such as a simulated training network classroom, relying on simulated training equipment to achieve network setup and equipment operation in the classroom. This method achieves network training and experience that is close to that of real equipment, and can complete network communication service testing that is consistent with actual communication equipment.

[0003] There are generally two ways to verify network planning schemes for communication networks. The first is to activate the network according to the network planning scheme based on the actual communication network environment, conduct network testing with the help of software tools, and finally evaluate the network planning scheme through tools or manual methods. This method can more realistically reflect the adaptability of the network planning scheme to network service assurance and complete the comprehensive evaluation of network performance. The second method is to use simulation software to build a simulated network and then conduct a performance evaluation of the network scheme based on the simulated network. This method is more convenient, but it can only describe network performance at the theoretical level and cannot completely replace the effectiveness evaluation of the actual network planning scheme.

[0004] Based on the above technologies, network planning schemes can be automated for verification using simulation training equipment. This is mainly because simulation training equipment is less expensive, easier to modify, and not limited by the need for external environment construction for wired and wireless devices in communication networks. It can be used in environments such as classrooms. Based on this idea, an automated verification method for network schemes based on simulation training equipment needs to realize functions such as automatic loading of simulation training equipment parameters, automatic network testing, integration, and simplification. Summary of the Invention

[0005] To address the problems raised in the background technology, this invention discloses an automated verification method for network schemes based on simulation training equipment. The simulation training network consists of simulation training equipment. A network planning system plans the network planning scheme for the entire simulation training network. The network planning system automatically distributes the network planning scheme within the simulation training network composed of simulation training equipment. The simulation training equipment automatically parses the planning scheme parameters. The network planning system issues network test schemes to the simulation training equipment. The simulation training equipment performs network tests and reports the test results to the network planning system. The network planning system statistically analyzes the information reported by the simulation training equipment to determine the network performance quality of the current scheme, thereby achieving the purpose of automatically judging the effectiveness of the current network scheme planning.

[0006] The network planning system consists of a network planning software module, a network testing software module, and a planning scheme effectiveness evaluation software module. The network planning software module can create and distribute network planning schemes, the network testing software module can create and distribute network testing schemes, and the planning scheme effectiveness evaluation software module can evaluate the effectiveness of network planning schemes. The simulation training equipment consists of a communication equipment module and a planning verification agent software module. The communication equipment module of the simulation training equipment simulates the service capabilities of real communication equipment, and the planning verification agent software module is used to realize the functions of automatic identification and loading of network planning schemes, automatic identification of network testing schemes, collection of network routing status, and reporting of network routing data and network test results.

[0007] The specific steps of an automated verification method for network solutions based on simulation training equipment are as follows:

[0008] S101. The network planning system plans the network scheme and sends the network planning scheme file to the simulation training network. The network planning scheme mainly includes the system parameters, interface parameters, and protocol parameters of the simulation training equipment. The network planning scheme is distributed in two ways: file and data stream. The network planning system distributes the scheme in three modes: broadcast, multicast, and unicast. The corresponding simulation training equipment obtains the network planning scheme file by listening to the broadcast, multicast, and unicast network packets respectively. This process is completed by the network planning software module of the network planning system.

[0009] S102. The simulation training device parses the network planning scheme file, matches its own planning parameters in the file with the ID number, and automatically loads them. The network planning scheme file parsed by the simulation training device is a planning file for the entire network. The file stores the parameters of each device by ID number. The simulation training device matches its own parameter file with its own preset ID number. The planning verification agent software module of the simulation training device completes the scheme reception and recognition of the network planning file and adds the parameters to the communication device module of the simulation training device.

[0010] S103. After the simulation training device automatically loads the planning parameters, it performs a soft restart. After restarting, it sends a message that the loading is complete to the network planning system. The internal process of the simulation training device is as follows: After the communication device module of the simulation training device completes the parameter writing, it replies to the planning verification agent software module. The planning verification agent software module controls the communication device module to perform a software restart.

[0011] S104. The network planning system creates a network test plan and sends the test plan to the simulation training network. The network test plan stores the test plan for each device by ID number. The main contents of the test parameters are test mode, test parameters, and test object information. This process is completed by the network test software module of the network planning system.

[0012] S105. The simulation training device parses the network test plan file, matches the test parameters with its own ID number in the file, and executes the test plan. This step is completed by the planning and verification agent software module of the simulation training device.

[0013] S106. The simulation training device reports the monitored network test results data and network routing data to the network planning system. This step is completed by the planning and verification agent software module of the simulation training device.

[0014] S107. The network planning system performs network performance statistical analysis. The main methods for network performance analysis in the simulation planning system are interoperability evaluation and network performance evaluation. Interoperability evaluation evaluates the business processing relationships of three elements: network architecture, data, and applications. Network performance evaluation evaluates five aspects: communication coverage, link transmission capacity, access user capacity, network interconnection capacity, and routing convergence capacity. The evaluation methods used are single-algorithm evaluation and multi-algorithm weighted average method. The main algorithm single-algorithm evaluation mainly involves each algorithm calculating the evaluation value of the network based on the data. Then, based on the results calculated by all algorithms, a comprehensive evaluation value of the current network is calculated by weighted average. This step is completed by the planning scheme performance evaluation software module of the network planning system.

[0015] After receiving the network test plan from the network planning system, the simulation training equipment performs network tests according to the test plan. The specific steps for the simulation training equipment to conduct network tests are as follows:

[0016] S201. After receiving the network test plan, the simulation training device identifies the test plan corresponding to its own ID in the test plan.

[0017] S202. The simulation training equipment will begin testing at the time specified in the test plan.

[0018] S203. The planning and verification agent software module of the simulation training equipment simulates and generates network test messages, and sends the network test messages to the communication equipment module of the simulation training equipment. The communication equipment module processes the data normally according to the routing table.

[0019] S204. After receiving a network test message from another simulation training device, the simulation training device processes the message according to the normal network processing logic.

[0020] S205. After the simulation training equipment test is completed, the network test results data are fed back to the network planning system.

[0021] The simulation training equipment collects routing change information of the equipment at fixed time intervals. When the network receives the network test plan, the simulation training equipment collects routing status change information of the equipment at preset time intervals and stores it in the simulation training equipment. After the test is completed, the simulation training equipment reports the stored network routing data to the network planning system along with the network test results data.

[0022] Network testing of the simulation training equipment uses Ping, Tracert, and dedicated bandwidth testing protocols. Test data is saved to the planning and verification agent software module of the simulation training equipment. This module has a dedicated IP address, and all its tests are initiated through this IP address. The routing table of the simulation equipment module contains a default route for this IP address; this route is hidden and invisible to the user. The simulation training equipment adopts an integrated design, only revealing the external appearance of the simulation equipment module, with the planning and verification agent software module embedded within it.

[0023] The beneficial technical effects of this invention are: it uses a simulated training network to realize the underlying support environment for verifying network planning schemes; it relies on this method to realize rapid loading of network parameters, automated network test execution, and network performance evaluation; it can realize rapid evaluation of network planning schemes; and end users can select the optimal network planning scheme to configure the network, thereby improving the efficiency of communication network usage.

[0032] S102. The simulation training device parses the network planning scheme file, matches its own planning parameters in the file by ID number, and automatically loads them. The network planning scheme file parsed by the simulation training device is the overall planning file of the entire network. The file stores the parameters of each device by ID number. The simulation training device matches its own parameter file by its own preset ID number.

[0033] S103. After the simulation training equipment automatically loads the planning parameters, it performs a soft restart. After restarting, it sends a message that the loading is complete to the network planning system. After the simulation training equipment automatically completes the loading of parameters in the network planning scheme, it needs to have an automatic restart function to make the parameters effective. The planning verification agent software module of the simulation training equipment will control the communication equipment module of the simulation training equipment to complete the restart function.

The planning and verification agent software module of the simulation training equipment simulates and generates network test messages, and sends the network test messages to the communication equipment module of the simulation training equipment. The communication equipment module processes the data normally according to the routing table.

[0042] S204. After receiving a network test message from another simulation training device, the simulation training device processes the message according to the normal network processing logic.

[0043] S205. After the simulation training equipment test is completed, the network test results data are fed back to the network planning system.

[0044] Network testing of the simulation training equipment uses Ping, Tracert, and dedicated bandwidth testing protocols. Test data is saved to the planning and verification agent software module of the simulation training equipment. This module has a dedicated IP address, and all its tests are initiated through this IP address. The routing table of the simulation equipment module contains a default route for this IP address; this route is hidden and invisible to the user. The simulation training equipment adopts an integrated design, only revealing the external appearance of the simulation equipment module, with the planning and verification agent software module embedded within it.

[0045] When simulation training device A1 needs to conduct a Ping test with simulation training device A2, the planning verification agent software in simulation training device A1 will initiate a Ping command with the IP address of simulation training device A2 as the target and the IP address of the planning verification agent software as the source address. Simulation training device A1 will forward the Ping data of the planning verification agent software normally, and simulation training device A2 will respond to the Ping command normally. The test process of this simulation training network is consistent with the effect of the actual communication network access user test response.
