Based on the analysis of development process of network computing model and the background of computing power network demand, the supply paradigm and three-layer service mode of computing power network are proposed. It is pointed out that computing power network is a network-centric new network computing model with integrated supply of multiple : computing power network; network-centric; network computing model.
