METHOD AND DEVICE FOR OBTAINING PERFORMANCE PARAMETERS OF OPTICAL NETWORK LINK

摘要

The present invention relates to a method and an apparatus for obtaining a performance parameter of an optical network link. Monitored actual optical power and theoretical optical power are acquired; modification is performed on a theoretical model by using the actual optical power and the theoretical optical power; and a performance parameter value in each node of the optical network is obtained from the modified theoretical model, so that a performance parameter given through the theoretical model is more accurate, thereby solving a problem in the prior art that a large deviation exists between a performance parameter calculated with the theoretical model and an actually measured result, and improving accuracy of the performance parameter given through the theoretical model.
