Problems solved by technology

[0007] (3) Disadvantages: Exponential complexity is required. For SDH networks that often generate a large number of alarms, this method is too inefficient
[0011] (3) Disadvantage: It is not suitable for SDH networks with complex topologies, because the delay of the alarm is difficult to determine, so it is difficult to judge the appropriate time window length, which also directly affects the accuracy of fault diagnosis

Embodiment Construction

[0044] The invention is an SDH fault location technology based on the alarm contribution degree, realizes the automatic fault location of the SDH network with complex topology, and has higher efficiency on the basis of maintaining accuracy.

[0045] Alarm contribution refers to the influence weight of a specific alarm type in the fault location process, which is defined according to the spanning tree corresponding to the alarm propagation and derivation process, and is determined by the height of a specific alarm in the alarm derivation tree and the size of its subtree.

[0046] SDH alarms have the characteristics of derivation and propagation. SDH network failures are mainly caused by abnormalities or errors in hardware devices or software management systems. Alarm symptoms are the external manifestations of failures. Most of the faults and abnormalities will be reflected in the overhead bytes of the SDH frame. The network element equipment will judge whether a specific fault ...

Abstract

The invention provides a contribution degree-based synchronous digital hierarchy (SDH) fault positioning method. The method is characterized by comprising steps: an alarm propagation model is constructed and an SDH alarm derivative tree is built; the contribution degree factor of each SDH alarm is calculated; fault reasons for each kind of SDH alarm data and times of the kind of SDH alarm caused by the reason are counted; the certainty factor of each kind of fault is calculated; the SDH contribution degree factors and the SDH fault certainty factors obtained after calculation are integrated to construct an SDH alarm fault reason list, and an SDH alarm rule knowledge base is constructed by the constructed SDH alarm fault reason list; and association model analysis is carried out, and SDH network fault positioning is carried out on the current SDH alarm. The method of the invention is based on the SDH fault positioning technology based on the contribution degree, faults of the topological complex SDH network can be positioned automatically, and the efficiency is higher on the basis of maintaining accuracy.

Description

technical field [0001] The invention relates to the field of transmission technology, in particular to a contribution-based SDH fault location method. Background technique [0002] In an SDH transmission network, network failures always occur with a large number of alarm messages, and maintenance personnel spend a lot of energy on dealing with alarms of network element equipment. A large amount of alarm data is sent from SDH communication equipment every day, and handling these alarms has become a tedious and challenging job for maintenance personnel. Therefore, it is a significant function for SDH maintenance personnel to locate faults by analyzing alarm data. [0003] The fault location of the SDH network refers to the correlation analysis based on the alarm data generated by the SDH equipment, so as to obtain the root cause of the network fault. The following describes the two commonly used fault location methods and their advantages and disadvantages: [0004] 1. Exha...
