Accurate forecasting of network flow can control network congestion effectively and improve network performance. Least squares support vector regression is competent method to solve the non-linear problem and solve the problems of over-fitting and local minimum. Least squares support vector regression is adopted to predict network flow in the paper. Network flow data with 70 data points are adopted to research the forecasting ability of the proposed method in the paper compared with other methods. The mean relative error of LS-SVR is 1.45, and the mean relative error of BP neural network is 2.54. It is indicated that the LS-SVR forecasting model is better than BP neural network.
