Routing deployment and resource scheduling in communication networks require accurate traffic prediction.Neural network-based models that extract the time-correlated or space-correlated features of traffic flow have been developed for traffic prediction.The conventional model that extracts space-correlated features of traffic RAW GOLDEN HONEY flow have the problem of high computational complexity and long training time which limits the model’s application on rapid routing deployment.This paper therefore proposes a layered training graph convolutional network (LT-GCN) to decrease the training time greatly with the nearly same prediction accuracy as graph convolutional network (GCN).Instead of training on parameters in all hidden layers simultaneously, LT-GCN develops a new layer-by-layer training pattern for multiple hidden layers to degrade the computational complexity in training process.

LT-GCN is then further integrated with gated recurrent unit (GRU) that is called LTGG model to achieve Desk and Hutch the joint extraction of time-correlated and space-correlated features of traffic flow for more accurate prediction.Experimental results demonstrate that LT-GCN outperforms the classical GCN model on training time and LTGG exhibits greater performance than other benchmark models on prediction accuracy.
