Abstract

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.

Description

technical field [0001] The invention belongs to the field of network traffic management, in particular to a power communication network traffic balancing method based on traffic forecasting. Background technique [0002] The power communication network is the second physical network in the power system, and its availability and stability directly affect the operation efficiency and safety of the power grid. Power network traffic management can quickly and accurately analyze network traffic trends, predict possible network congestion and idle conditions, and reduce network load balance. With the expansion of the network scale and the increasingly complex network environment, the services and applications carried on the network are becoming more and more abundant. Correspondingly, higher requirements are put forward for the management efficiency of the information network. Therefore, strengthening network management construction is an urgent problem to be solved in power grid...
