Problems solved by technology

[0004] However, since the alarm correlation analysis rules are pre-defined, existing faults can only be analyzed based on the correlation rules, and because the network composition itself is very complex, the root cause results after correlation analysis are often inaccurate
When a network failure occurs, the alarm itself and the correlation analysis data also lack extensive and effective retrospective verification methods, and cannot efficiently and accurately determine the root cause of the alarm

Embodiment 1

[0026] refer to figure 1 , which is the first embodiment of the present invention, this embodiment provides a snapshot and playback method of network topology, including:

[0027] S1: collect and store the device information of the whole network through the network device information collection and alarm analysis module 100, and generate an alarm according to the prefabricated rules of the network management system;

[0028] What needs to be explained is that before information collection, a communication connection between the network management system and the monitored equipment needs to be established, and the communication between the two can be established using the snmp communication protocol.

[0029] After the communication is established, the network equipment information collection and alarm analysis module 100 collects various data of the monitored network equipment, including: equipment communication status, equipment component status, link status, routing informat...

Embodiment 2

[0049] In order to verify and explain the technical effect adopted in this method, this embodiment selects traditional network management and adopts this method to conduct a comparative test, and compares the test results by means of scientific demonstration, so as to verify the real effect of this method.

[0050] Traditional network management uses a relational database to store historical data, which cannot efficiently monitor a large number of network devices. In order to verify that this method can query historical data efficiently and with a short delay compared with traditional network management, traditional network management (mariadb, Jincang) will be used in this embodiment Compared with this method, the data query time is measured and compared; the results are shown in the following table.

[0051] Table 1: Comparison of data query efficiency under the same configuration.

[0052]

[0053]

[0054] It can be seen from the above table that in terms of statisti...

Embodiment 3

[0056] This embodiment is different from the first embodiment in that it provides a snapshot and playback system of network topology, including:

[0057] The network device information collection and alarm analysis module 100 is used to collect information and generate alarms for devices in the entire network; that is, to collect device configuration information and performance indicators in a polling manner. Device configuration information includes but is not limited to: device name, model , type, manufacturer, etc. Device performance indicators include but are not limited to: CPU, memory usage, traffic, voltage, optical power, communication status, etc.; then generate performance indicator alarms based on the performance measurement threshold set by the network management system, or according to network management business requirements (such as: Configuration changes, configuration exceptions) generate various business alarms.

[0058] Time series storage and snapshot gene...

Abstract

The invention discloses a snapshot and playback method and system for network topology, and the method comprises the steps: carrying out the collection and storage of the equipment information of a whole network through a network equipment information collection and alarm analysis module, and generating an alarm according to a preset rule of a network management system; when the alarm is generated, the time sequence storage and snapshot generation module generating a section snapshot according to the alarm generation time and the configured section generation period; loading the section snapshot through a network topological graph playback module, so that the whole network topology is recovered to the section snapshot occurrence moment, and snapshot playback is carried out. According to the method, the network operation and maintenance personnel can backtrack the network state at any historical time through two modes of periodically inserting the snapshots and the alarm section snapshots, so that the problem backtracking efficiency is improved, and the production loss caused by fault alarm is reduced.

Description

technical field [0001] The invention relates to the technical field of a network management system in an information management system, in particular to a snapshot and replay method and system of a network topology. Background technique [0002] With the continuous development and continuous deepening of the information technology revolution, network communication technology is pervasive in every corner of work and life, applied in various scenarios, greatly improving and improving the quality of work and life, and people are increasingly relying on network communication . This requires that the network must have extremely high reliability and security. Therefore, a network management system focused on continuous monitoring and management of the network came into being. It can accurately record the status of network equipment, various index data, link load, bandwidth utilization, network service quality, etc. Through the recording and analysis of these original information...
