Method And Apparatus for Establishing Network Performance Model

A method and apparatus for establishing a network performance model. The method includes: determining, according to performance data provided by network nodes and the probability of the performance data, a parameter α showing the correlation of the performance data of different network nodes in a whole network and a parameter β showing the distribution pattern of the performance data in the network; and establishing a Latent Dirichlet Allocation, LDA, network performance model by using the determined parameter α and the parameter β.
