| 摘要 |
The present invention relates to a method and apparatus of predicting network performance, wherein the method includes: obtaining M performance parameter data of a link; calculating a cloud model digital feature of network performance of the link according to the M performance parameter data; calculating N predicted performance parameter data of the network performance of the link according to the cloud model digital feature; and raising a prediction alarm that the link has a risk of exceeding a limit if there is data exceeding a preset upper limit value in the N predicted performance parameter data, wherein M and N are preset positive integers. According to the network performance prediction method and apparatus provided in the present invention, a change trend of network performance is analyzed according to real-time monitored data of the network performance of the link to predict future performance parameter data, and whether an alarm is raised and protection switching is performed is determined based on the prediction. |
