Network traffic prediction can effectively reduce the network congestion rate and improve the quality of network service, traditional methods can not describe the chaotic characteristics of the network traffic, a novel prediction model based on PHR-ELM is proposed in this study. Firstly, network traffic is analyzed and processed by chaos, and phase space reconstruction is used to reconstruct the network traffic data, and secondly, extreme learning machine is used to realize the accurate prediction of network traffic, At last, the simulation test of network traffic prediction is realized, the proposed model can effectively fit chaotic characteristics, and accurately predict the change trend of network traffic, the forecast effect is better than traditional models, the results have verified the validity and superiority.
