英文摘要：

In order to obtain more accurate prediction of network traffic and reduce the congestionfrequency of network, a novel network traffic prediction model based on improved extreme learning machine is proposed in this paper. Firstly, the delay time and embedding dimension are determinedaccording to the chaos of network traffic, and secondly, extreme learning machine is used to simulate the change rule of network traffic which standard learning machine is improved to improve the learning speed and performance, finally, the feasibility of is verified by the network traffic data. The results show, the network traffic prediction results of the proposed model are more reliable Compared with other network traffic prediction models, can describe the change trend of network traffic and improves the prediction accuracy of network traffic.
