Federated network operations become more and more important and the central challenge for Future Internet testbeds around the world. Federated network operations on Future Internet need to meet at least two conditions based on the general definition of federation [1]. First, multiple distributed network domains agree upon standards of network operations. Second, internal network operation of each domain is autonomous under its own control. Under the fundamental requirements, this paper presents a framework that federates and operates the autonomous distributed networks (ADNs) in the perspective of virtual network operations and end-user oriented network management on end-to-end network slices. In addition, we propose a virtual federated network (VFN) environment as a common federation interface between ADNs, associated with three key functionalities such as core network resource schema and representation, operational data exchanges, and end-to-end federated network operations. The performance consideration of this scheme includes the fast convergence of state updates on each ADN through VFN interface, as well as reliable and scalable operational dataset management of the federated Future Internet testbeds.
