A method and system for multi-network correlation analysis

Abstract

The invention discloses a method and system for analyzing multiple-network relation. Firstly, a routing protocol is acquired through a virtual router so as to find a network device, real-time monitoring and diagnostic analysis of a protocol state of the network device is performed, and an alarm is given when anomalous change occurs. Interdisciplinary alarm correlation analysis of a bearing network, a signaling network and a transmission network is performed. When the network device shuts down, a network device associated with the network device in a network is subjected to resource analysis and positioning, impact level is judged, and impact result state information is shown in a topological interface. By adopting the technical scheme, powerful support is provided for quick fault position and repair, an impact range of the whole network can be comprehensively and accurately mastered, customer perception is effectively improved, and the network is ensured to operate in high-stability, high-quality and high-efficiency mode.

Description

technical field [0001] The invention relates to the technical field of network monitoring, in particular to a method and system for multi-network correlation analysis. Background technique [0002] With the advent of the entire network IP era, more and more services are carried on the IP network. How to effectively monitor the operation quality of the IP network, intuitively and quickly locate the network fault point and the scope of influence, and provide comprehensive support for network maintenance and management. Command and dispatch work provides strong support, which has become an important proposition for future network maintenance and development. [0003] At present, the following two methods are generally adopted for network operation monitoring methods: one method is to collect and monitor network equipment alarms, and analyze faults based on fault phenomena and network maintenance experience; the other method is to use network probe instruments Connect to the ma...

AI Technical Summary

Problems solved by technology

[0005] 1. Only a single network can be monitored, and the operation status of other external business networks is not involved. After a fault occurs, even if multiple networks are affected, the specific root cause of the problem cannot be determined from each other, and it can only be maintained manually. Analyze experience, which will increase the fault duration, which will affect customer perception

[0006] 2. Due to the lack of correlation between networks, the existing network monitoring system can only monitor fault points of independent networks, but cannot be mapped to other professional networks and business applications. It is limited and closed, making it impossible to monitor faults Make an accurate judgment and analysis of the resulting network-wide impact,
