The European Commission (EC) have funded a large number of diverse Future Internet Research and Experimentation (FIRE) testbeds and most are aimed at one particular technology due to the complexity of developing a testbed. For example, the OFELIA project in Europe is an OpenFlow networking testbed while BonFIRE offers a multi-site cloud computing facility. In the planned use cases of these testbeds, it was not expected that an experimenter would want to reserve and use them in one single experiment, but the federation of heterogeneous testbeds could bring a huge benefit that is larger than their sum. The EC has therefore decided to fund the Fed4FIRE project to achieve this important goal. The successful federation of FIRE testbeds requires two main objectives to be achieved. The first objective is that all testbeds within the federation should have the same common way of discovering and reserving their resources. In order to solve this problem, a common federation Application Programming Interface (API) is applied on top of any existing API that a testbed already has. A common API has the main benefit that a single simple tool can be used to discover and reserve any resources inside the federation. The main limitation with a common API is that diverse resources need to be discovered and reserved. This problem is solved through the use of suitable Resource Specification documents to correctly identify heterogeneous resources. The second objective is the interconnectivity of the different testbeds. Two interconnectivity approaches are concurrently being investigated in this context of Fed4FIRE: each testbed can peer with other testbeds based on the availability of dedicated connections between them and in the second approach, each testbed is connected to a central exchange point where the stitching of the connection between different testbeds is done. Fed4FIRE is also investigating other research topics such as the authentication and authorization of experimenters, uniform monitoring of resources of the different testbeds and automated experiment deployment and collection of results. In summary, Fed4FIRE is enabling a simplified but yet powerful way for experimenters to interact with a diverse set of testbeds which will lead to innovative ICT solutions with a significant reduction of their development time.
