Transmission network universal switch analytical method based on switch factor relativity analysis

Abstract

The invention relates to a method for analyzing general rearranging of transmission network based on relativity analysis of rearranging factors. The method includes the following steps: A. when the network element generates rearranging massages, all the rearranging factors generated recently are obtained to form a collection of factors to be analyzed. B. the rearranging factors resulted from Step A are filtrated according to time relativity. C. the rearranging factors resulted from Step B are filtrated according to space relativity. D. the rearranging factors resulted from Step C are filtrated according to business relativity and the unprotected rearranging factors in business are eliminated. E. the derivative factors and rearranging massages resulted from Step D are eliminated. F. the entity that generates root factors and that resulted from E is located on the object tree. G. the rearranging direction, the rearranging reason and the business view after rearranging are analyzed according to the protection type and the ending time of the rearranging factors. The method of the invention can, without considering equipment types, realize unified analysis of rearranging features and present the whole business rearranging view as well as the fault reasons that cause rearranging.

Description

technical field [0001] The present invention relates to a general analysis method of switching state within the category of transmission network, more precisely, the present invention relates to a general switching analysis method of transmission network based on correlation analysis of switching factors. Background technique [0002] In the field of transmission network, services refer to channels that carry user information, including 2M circuits, VC4 channels, etc. In order to improve the availability of the transmission network, ITU-T has defined two mechanisms, protection and restoration. Among them, the protection mode is realized by using the reserved spare resource to replace the transmission entity that causes failure or performance degradation when the service fails. Switchover refers to the switching action between the active resource and the standby resource, including the switching of the failed resource to the standby resource, and the switching from the stand...

AI Technical Summary

Problems solved by technology

[0004] 1) Faulty switching occurs on protected services. Generally, protection services correspond to VIP customers. Once a switching occurs, it means that the main channel has a serious failure and needs to be dealt with in time.

[0005] 2) When a faulty switchover occurs, the quality level of the protected service is reduced to an unprotected service. Once the backup channel is not good, it will cause service interruption or bit error, and will face economic losses. At this time, it is necessary to pay close attention to the status of the backup channel

[0012] 3) The message reported by the device is the first priority. If the granularity is set to 2M, once the switchover triggers many switchover messages, other messages will be overwhelmed, so that the maintainer cannot pay attention to it in time.

[0013] 4) The computing power of the device is limited

However, a natural problem faced by the master control point is how to uniformly deal with the characteristics of various devices. It will also lead to differences in switching messages
