Abstract

The embodiment of the invention provides an optical network protection control method, an optical network protection control device and a network management server. The optical network protection control method comprises the steps of: obtaining performance parameters of an optical fibre link through a performance monitoring module arranged on the optical fibre link of an optical network, wherein the obtained performance parameters of the optical fibre link include at least one of an optical fibre performance parameter and an optical signal transmission performance parameter; and, judging whether the optical network needs to be protected or not currently according to the obtained performance parameters of the optical fibre link, and if so, starting optical network protection, wherein the started optical network protection includes at least one of automatic power reduction protection and automatic switched protection. Visibly, the performance parameters of the optical fibre link can be obtained; on this basis, whether starting of the optical network protection is triggered or not is judged; therefore, attention requirements of operators on the optical network performance can be satisfied; and relatively comprehensive and reliable optical network protection can be provided.

Description

technical field [0001] The invention relates to the communication field, in particular to an optical network protection control method, device and network management server. Background technique [0002] In optical communication systems, optical power is lost due to accidents such as fiber cut, equipment failure, or optical connector pulling out. On the one hand, for the sake of personnel safety, the APR (Automatic Power Reduction, automatic power reduction) protection process will be started when the optical power in an optical transmission section of the main optical channel is lost. After the optical fiber link is normal, the communication will automatically resume, and the APR optical power It is required to meet the standards of BSEN 60825-1-1994 and BSEN 60825-2-2000. On the other hand, for the sake of system protection, APS (Automatic Protection Switched) is generally added to the optical transmission link. When the working link fails, it will automatically switch to...
