Description The primary objective of the FELIX project is to create a common framework in which users can request, monitor and manage a slice provisioned over distributed and distant Future Internet experimental facilities in Europe and Japan. FELIX, submitted as a joint effort of two independent consortia (i.e. FELIX-EU in Europe, FELIX-JP in Japan), builds strong foundations for a federation framework by investigating emerging technologies and Software Defined Networking control frameworks (e.g. Open Grid Forum’s NSI and OFELIA OCF) for the practical applicability in the project.To achieve its goals, FELIX proposes a new SDN-oriented service architecture capable of federating heterogeneous high-end FI facilities (e.g. OFELIA, JGN-X RISE) through high capacity NSI-enabled networks (e.g. JGN-X, GéANT, GLIF or NRENs), offering the creation of the experimental landscape in a dynamic and seamless way in order to satisfy demanding needs of European and Japanese research communities. The on-demand setup of OpenFlow-based network slices, including compute and storage resources, will be realized through an extended-NSI, the OGF standard for provisioning of end-to-end network services over research networks.The FELIX platform will be deployed and demonstrated in a world-scale test-bed involving key FI experimental platforms in Europe and Japan interconnected by high speed dynamic research networks. The use cases developed in the project will be demonstrated at influential international events in Europe and Japan, promoting unique capabilities of the new federation framework in order to stimulate the use of experimental facilities in both regions.It is expected that the project will enable and encourage closer and more extensive bilateral cooperation in FI research and experimentation, as well as strengthen the participation of both EU and Japanese communities in the increasingly important global collaborations in the area of FI research and development.
