The electric power data communication network, as the support of electric power industrial operation and maintenance management, is one of the fundamental establishment. Corresponding with the development of communication technology, the power industry has also experienced a data communication network evolution from the traditional TDM technology to IP technology. In recent years, the construction of power information is basically on traditional ATM and TDM technology data communication network in Pingdingshan. However, with the development of intelligent network application deepening, the high cost and low efficiency of ATM and TDM become the bottleneck which begin to restrict the further development of information technology. So it becomes the inevitable choice for Pingdingshan power data communication network to construct the next generation, highly reliable and multi service bearer network on the basis of the latest IP communication technology.
