Abstract: At present, it is possible for service routing method based on sequential configuration to cause the high risk of power communication network. To solve the key service routing problem, a routing allocation strategy based on multiple ant colony algorithms was proposed, considering all parameter requirements of current network and business distribution factors. Firstly, the routing allocation model of electric power communication network service was built up. By defining the channel pressure, the model with minimum channel pressure was designed. Then multiple ant colony algorithms were used to solve the problem. Finally, the simulation experiment based on the current network topology was carried out. Simulation results showed that the proposed method could provide efficient network planning solution in different scale networks with higher performance than other methods.
