QoS evaluation method of optical network based on optical network alarm mega data

摘要

Automatic evaluation of optical network service quality is a research hotspot in optical network operation and maintenance management.Based on the large alarm data of optical netvvork,a evaluation method of optical network service quality based on FCM and rough set theory is proposed in this paper. First, the evaluation index is selected based on the classification statistics of alarm data; Secondly,adopt the FCM method to fuzzy clustering of raw data,and locate the fuzzy language item;Finally,extract the optical network service quality evaluation rule and establish system of the optical network service quality evaluation. The test shows that the accuracy of this method is 73% based on the 22 alarm samples in an optical network and the accuracy of the evaluation increases with the increase of the number of samples.
