The invention relates to a traffic balancing method for an electric power communication network based on traffic prediction. The traffic balancing method comprises the following steps: firstly, detecting a node link state to acquire node traffic data, and setting a load threshold of the node; secondly, analyzing the state of the traffic data at certain time and predicting the traffic during the future certain time slot; meanwhile, judging whether the possibility of overload exists or not; performing link shunting processing on a link which is predicted to possibly exceed a threshold; finally, dynamically counting and adjusting the load degree of the whole network and enabling the whole network to operate at an optimized state. According to the method disclosed by the invention, the node traffic can be reasonably limited, and the operation efficiency of the link is greatly improved; the selection of a node threshold is controlled by analyzing the balance degree of the whole network, so that the distribution of a data flow is developed towards the integral optimization of the network.
