Problems solved by technology

[0004] Based on this, it is necessary to provide an alarm transaction extraction method and system for the low efficiency of alarm transaction extraction. The method and system first evaluate the quality of time segment division, determine the optimal division of alarm time The extraction of alarm transactions in each time period obtained by optimal division improves the efficiency of alarm transaction extraction for alarm time series and provides strong support for alarm analysis

Embodiment Construction

[0031] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] In one example, see figure 1 The flow diagram of the method for extracting alarm transactions is shown, and the method specifically includes the following steps:

[0033] S100 divides the alarm time series into several time periods;

[0034] The alarm time series is a collection of time points where alarms occur in the original alarm data in the network, that is, the alarm time series is composed of alarm time or alarm time points, for example, the alarm time series V={t i},i=1,2,...,K, where, t i Indicates the moment when the i-th alarm occurs, and there are K alarms in the alarm time series; the so-called division of the alarm time series refers to the use of a certain algorithm to cluster each alarm time into several time series according to the distribution characteristics of the alarm time series par...

Abstract

The invention relates to an alarm transaction extracting method and system. The method comprises the following steps that an alarm time sequence is divided into a plurality of time sections; differences between the sections of the alarm time sequence are determined according to the central time points of every two adjacent time sections, and meanwhile differences in each section of the alarm time sequence are determined according to all time points in the section; optimal division of the alarm time sequence is determined according to a ratio of the differences between the sections and the differences in each section; alarm transactions in the next time section under optimal division are extracted through a sliding time window method. According to the alarm transaction extracting method and system, the division quality of the time sections of the alarm time sequence is firstly reasonably evaluated to determine optimal division of the alarm time sequence, and then alarm transaction extraction is performed on all the time sections under optimal division, so that the alarm transaction extraction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of network risk management and control, in particular to a method and system for extracting alarm transactions. Background technique [0002] The alarm information generated by each device in the network is very important for network risk analysis. Due to the complexity of alarm propagation in the communication network, the occurrence of faults is often accompanied by a large number of related alarms, which brings great difficulties to the precise location of faults. Correlation analysis of alarms is the basis of fault location. Use association rule mining to obtain effective rule knowledge to assist fault location, discover fault location knowledge hidden in a large number of original alarm information, and use valuable knowledge to guide network fault diagnosis. In this way, network faults can be managed in a higher level, all-round and more accurate manner, the efficiency and intelligent level of network ...
