Positioning method of failed link and alarm root cause analyzing method, equipment and system

Abstract

The embodiment of the invention discloses a positioning method of a failed link as well as alarm root cause analyzing method, equipment and system, wherein the alarming root cause analyzing method comprises the steps of: acquiring at least one alarm of a managed network; sending alarm generation time to positioning equipment of the failed link; receiving a mark of the failed link, a mark of damaged edge equipment and an equipment interface mark of the damaged edge equipment, which are sent by the positioning equipment of the failed link; querying whether the at least one alarm contains the alarm from the failed link or not, if so, marking the alarm from the failed link as a root cause alarm; judging whether the alarm from the damaged edge equipment exists or not, if so, judging whether a service object corresponding to the alarm is loaded on an equipment interface of the damaged edge equipment or not, and if so, marking the alarm from the damaged edge equipment as a derivative alarm. The embodiment of the invention can realize the network-level alarm root cause analysis, prevent the route information of all equipment in the network from being acquired and reduce the network resource consumption.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a faulty link location method, an alarm root cause analysis method, equipment and a system. Background technique [0002] In computer networks, alarm root cause analysis is usually divided into device level alarm root cause analysis and network level alarm root cause analysis. Among them, device-level alarm root cause analysis focuses on the relationship between alarms generated by a single device; network-level alarm root cause analysis focuses on the relationship between alarms generated by multiple devices. The root cause analysis of device-level alarms has been maturely implemented, but the root cause analysis of network-level alarms can only do limited analysis because the network management system lacks end-to-end network path information. [0003] An existing alarm root cause analysis solution is implemented based on a business object model, and the dependency r...

However, this solution requires the network management system to collect the routing information of all devices in the network in real time, which consumes a lot of resources of the network management system, and it is difficult to ensure real-time performance; when the amount of routing information is relatively large, it will inevitably consume a lot of network resources. Bandwidth resources and device resources, thus affecting network performance, ultimately unable to fully realize the root cause analysis of network-level alarms
