Abstract: Network delay is an important performance metric of IP network which reflects network path's workload characteristics. The precise prediction for network delay is an important basis on congestion control and route selection.A new multi-step prediction method was proposed for network delay prediction based on the random neural networks,this method overcomes the disadvantage traditional time-series method and neural network method. Compared with traditional RBF network and AR model,the experimental result indicated that the proposed model has better accuracy for single steps and multi steps prediction.
