The Design for Connection Scheme of Access and Backbone Network in Power Communication System

With the development of electric power business and Smart Grid, many different access technologies are emerge in access network. Meanwhile, transmission technologies with high speed and large capacity are used widely in backbone network. We take into account the key technologies in access and backbone network, design the connection scheme between the access and backbone networks from practical application scenario. The scheme is combined technology methods, interface design, and so on. There is a strong guide significance in this paper.
