Abstract(in English) With accurate network traffic prediction, future communication networks can realize self-management and enjoy intelligent and efficient automation. Gaussian process, which encodes domain/expert knowledge into the kernel function, allows better learning and understanding of the traffic process from a Bayesian perspective. However, the evolving nature of network traffic challenges existing models to adaptively learn and predict its behavior. To this end, we establish a dynamic learning framework for multi-slot-ahead network traffic prediction based on Gaussian process. Specifically, 1). To track the dynamic traffic characteristics, we use a mixture of Gaussian in the spectrum domain to approximate the optimal kernel adapting to the designated training dataset, and dynamically discover the patterns at different times and time-scales. 2). To predict in a large time horizon without significantly hurt the performance, we adopt linear model of coregionalization to fully exploit the output correlations, and establish an integrated multi-slot-ahead prediction framework. Finally, our proposed algorithm is evaluated by simulation to show its superiority over the conventional schemes such as stochastic based ARIMA, deep learning based LSTM etc.
