Federation between different testbeds is a key objective of OneLab. The term federation refers to a connection between testbeds which allows the mutual sharing of their resources.

OneLab's flagship testbed PlanetLab Europe is currently working towards federation with the testbeds in this section. This federation can be PlanetLab-based or OMF-based. Other testbeds soon to be added include 6P-UOA, ORBIT and HEN.
