The network performance comprehensive evaluation model based on the cloud model and entropy theory was presented to solve the fuzzy and random problem in performance evaluation.The entropy weight method was used to compute the evaluation factors' weights.The method makes the weight determination reseanable.The cloud model was used to realize the uncertain map between comment and evaluation factor value.The method keeps the uncertainty in evaluation.A case study using simulation method was implemented in VoIP network.Compared with the normal fuzzy evaluation method,the model achieves the right evaluation result and its probability.
