MultiNext measuring concurrent multipath transmissions in an experimental facility

A major feature of the Future Internet is the federation of resources, e.g. for forming application-specific routing slices. Currently this can be done by using overlay technologies. Network virtualization techniques, as investigated in the VINI project, further advances this concept to allow the combination of partial resources on network nodes and links. While we do not yet have standard solutions for the general Internet, federation concepts are currently tested across testbeds in Europe, USA and Asia in order to combine testbed resources for experiments like FIRE and GENI. As network scientists we need such testbeds in order to validate theoretical results for large-scale highly distributed environments and under real network conditions. But since testbeds nowadays are typically customized to particular user groups and offer different capabilities some experiments require the federation of testbeds to profit from a broader set of characteristics and functions.
