Embodiment Construction

[0049] In order to describe the present invention more clearly, the following examples are given in conjunction with the accompanying drawings to further illustrate the present invention.

[0050] The description of the invention does not involve the specific type of transmission equipment, but only provides a general and rapid fault location analysis method for the general rules of fault factors.

[0051] In the present invention, the general correlation is mainly analyzed from three aspects. The first is time correlation. The principle is that the fault factor caused by a fault is related to the fault in time. A series of entity alarms, and the time difference between these alarms occurring on adjacent ports (two physical ports directly connected through optical fibers are called adjacent ports) generally does not exceed 3 seconds, and the time difference between alarms that occur on non-adjacent ports in the same node does not exceed 30S (The time difference between photoelec...

Abstract

The invention relates to a method of positioning faults in the transmission network on the basis of correlation analysis, comprising the following: obtaining all the fault factors happening in the range to be analyzed to form a factor collection to be analyzed; dividing the fault factors into a plurality of fault groups according to time correlation and rendering the same processing priority to each fault group; restraining secondary fault factors in each fault group and retaining principal fault factors according to the space correlation; restraining the secondary fault factors and retaining the principal fault factors in each fault group according to traffic correlation; deleting empty fault groups in the plural fault groups; and obtaining fault reasons and fault processing mode according to the knowledge base. The method can reduce the probability that the knowledge base is big and is not convenient to be maintained and can lower the probability that the rules are contradictory, can improve the alarming compression ratio, and can be adapted to the diversity of equipment types, service types and versions. At the same time, the treelike structure of the fault groups can reflect the fault analyzing processes clearly, which facilitates judging and correcting the faults manually.

Description

technical field [0001] The invention belongs to the technical field of transmission network, and in particular relates to a general analysis method for locating faults within the scope of transmission network by utilizing time correlation, space correlation and service correlation. Background technique [0002] As the transmission rate and capacity of the transmission network increase, the loss caused by even a small fault is catastrophic. Therefore, in order to minimize the loss, it is necessary to quickly locate the fault, determine the processing priority, and process the most in the shortest time. Emergency failure, shortening the troubleshooting time. [0003] The current level of equipment intelligence is higher than before. The equipment itself, such as a single disk, can block the associated alarms of different levels generated by the same entity according to the level defined by ITU-T. However, the alarm suppression function provided by the equipment is currently li...
