Embodiment Construction

[0055] refer to figure 1, the present invention takes the analysis control engine as the control module, and implements the real-time correlation of network faults by interacting with the information model query interface, event extraction interface and preprocessing module, real-time network parameter detection interface, fault scenario table generation module, and topology synchronization module analyze. The specific steps are:

[0056] 1. The event extraction interface uses different protocols (SNMP / SYSLOG, etc.) to extract fault event information from various network devices and business objects, and converts their format into a unified internal format, and then through the event preprocessing module, these The event information is compressed and filtered (according to the preset filter), and written into the original event list; the processing effect can be effectively improved by preprocessing the original event;

[0057] 2. The analysis control engine selectively read...

Abstract

Information of failure events from various network devices and service objects is written into original event list. Correlation analysis is carried out for events read by analyzing and controlling engine from the original event list according to levels of original event and selection of classes. The dynamic analytical algorithm synthetically handles information in each area such as scene of historical fault analysis, dynamic performance parameters of network, dynamic topology information and time character of event etc. comparing with prior art, the invention overcomes disadvantages of overlooking information of dynamic network state, dependent on preset rule and lack of auto study ability etc. The invented method provides effective correlation analysis, fault reason analysis and location in real time when storm of network fault happens.

Description

Technical field [0001] The invention belongs to the field of computer network communication, and in particular relates to a method and system for performing real-time correlation analysis on network failure events based on domain comprehensive information in network management. Background technique [0002] In computer and communication networks, when a certain device or service fails, a series of network events will be caused due to the close connection between the device, service and business, and the network management system responsible for monitoring the network will send event notifications through the device Or the polling monitoring of the network management system will find a large number of abnormal events, which will be reflected on the management interface of the network administrator through SNMP Trap, Syslog or Indication, thus appearing as a "network failure storm". Because this kind of fault storm often leads to a large number of events in a short period of t...
