With the rapid growth in network scale and capacity, the traditional peer-to-peer (P2P) network management model is not suitable. We present a novel network management framework model called "cloud to cloud" (C2C). A number of management services are deployed on geographically distributed servers to form a management service cloud, and the NMS uses services provided by this cloud to manage the underlying physical network cloud. The paper describes the general characteristics of the C2C model, and then introduces its architecture, information model, communication model and functional model. Finally, we give an implementation framework of the C2C model for wireless access network management.
