Enhanced alarm inhibition method applied to optical transmission device

Abstract

The invention discloses an enhanced alarm inhibition method applied to an optical transmission device. The method comprises the following steps: 1, an alarm processing module establishes three layers of alarm tables; 2, the alarm processing module obtains all physical alarms of the device at present and records all physical alarms in an actual physical alarm table; 3, the alarm processing module filters all physical alarms recorded in the actual physical alarm table by using an alarm inhibition operation and records the filtered physical alarms in a total alarm table; and 4, the alarm processing module checks the total alarm table, records a check alarm result in a user report alarm table, and meanwhile reports the check alarm result to the user. By adoption of the enhanced alarm inhibition method, the alarm relation model can be dynamically updated according to a service protection switching state, thereby solving the problem that the change of the protection switching state in the alarm inhibition operation causes different detection points of alarm report to affect the accuracy of an alarm correlation analysis result.

Description

technical field [0001] The invention relates to the technical field of optical transmission communication, in particular to an enhanced alarm suppression method applied to optical transmission equipment. Background technique [0002] Optical transmission equipment generally refers to equipment such as wavelength division multiplexing (WDM), optical synchronous digital transport network (SDH), packet transport network (PTN) and optical transport network (OTN), which are widely used in access networks, metropolitan area networks and backbone transmission. network. Optical transmission equipment often adopts wavelength division multiplexing technology at the optical layer, and technologies such as mapping, multiplexing, and crossover at the electrical layer, so that the transmission network can flexibly and efficiently transmit data streams of various service granularities. Optical transmission equipment supports rich overhead management protocols, which can realize end-to-end...

Problems solved by technology

[0005] Some of the existing alarm suppression implementations do not consider the change of the protection state at all, and some mark the service where the alarm is located by adding a service source point to the final alarm information, but ignore the detection point that the change of the protection state causes the alarm to be reported Different, the analysis of alarm correlation will have an impact, and it may happen that the alarms that should be filtered are not shielded, or the alarms that should be displayed are filtered out
