The OFELIA experimental facility is based on OpenFlow technology. A set of five islands creates a diverse OpenFlow infrastructure that allows experimentation on multi-layer and multi-technology networks provided by the different islands.

- Berlin (TUB) – partial replacement of existing campus network with OF-switches
- Gent (IBBT) – central hub, large-scale emulation
- Zürich (ETH) – connection to OneLab and GENI
- Barcelona (i2CAT) – L2 (NEC) switches and Optical equipment (ROADM ring)
- University of Bristol (UNIVBRIS) – national hub for UK optical community; L2 (Extreme) switches, FPGA testbed
