Problems solved by technology
This automatic inspection method is a static inspection, which is usually an offline inspection before the network is opened. If online real-time inspection is to be realized, it is necessary to continuously send and collect information to network devices. It is not suitable for large-scale networks, and the inspection process is inefficient. and can have a significant impact on network performance

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. In order to overcome the problems of low efficiency, large impact on network performance, and poor real-time performance in the inspection process of network device configuration changes in the prior art, this embodiment proposes an automatic real-time inspection method for network device configuration using the OpenFlow protocol. By setting another OpenFlow controller to monitor the flow table status in real time, once the network configuration changes, the network device will send flow table change information to the OpenFlow controller. If the network device is invaded or the main network controller is maliciously modified, the network management Therefore, as a configuration inspection device, the OpenFlow controller can monitor and collect configuration changes of network devices in real time, and then the OpenFlow controller compar...

The invention discloses an automatic checking method for standardized configuration of railway data network equipment, comprising the steps of: deploying an OpenFlow agent software on the network equipment, configuring the OpenFlow agent software into a multi-controller mode, and establishing a connection between the OpenFlow agent software and network configuration checking equipment by OpenFlowprotocol communication; sending, by the OpenFlow agent software, change information of a network equipment forwarding table to the network configuration checking equipment in real time, and performing, by the network configuration checking equipment, standardized check on the change in configuration of the network equipment by comparing standardized configuration strategy files of the organizations. The method realizes automatic and real-time check on the network equipment. Compared with a periodic checking method, since the flow table information is not required to be queried periodically, the network traffic can be effectively reduced, and the method can be applied to configuration checking of large networks and is simple, efficient and intelligent.
Description
technical field [0001] The invention relates to the technical field of network equipment safety management, in particular to an automatic inspection method for standardized configuration of railway data network network equipment. Background technique [0002] From the perspective of security configuration management of network devices, the current configuration inspection of network devices using the OpenFlow protocol has not realized real-time automatic verification. Major threats, if network device configuration changes cannot be managed and identified in a timely and effective manner, will eventually lead to hidden dangers in network security. For example, the Chinese invention patent with the announcement number CN104539453A discloses "a method for checking and analyzing network equipment configuration for rail transit signaling systems". Spreadsheets to automate configuration checks with application visualization scripts. This automatic inspection method is a static i...
