Building Intelligent Future Internet Infrastructures: FELIX for Federating Software-Defined Networking Experimental Networks in Europe and Japan

Future Internet (FI) test test beds are experimentation platforms comprising different types of resources and located in various geographical locations. The ability to leverage heterogeneous resources across these infrastructures is a key concept in the creation of future intelligent network technologies. This article summarizes the development of a software-defined infrastructure (SDI) that includes not only networks, but also compute resources and monitoring. To our knowledge, this article is the first actualization of SDI using a generalized architecture for the creation of future intelligent infrastructures. We also present use cases that validated the Federated Test Beds for Large-Scale Infrastructure Experiments (FELIX) framework and provided insights in the establishment of a transcontinental SDI between Japan and Europe.
