A National Programmable Infrastructure to Experiment with Next-Generation Networks

We have set up the first multi-domain P4programmable network in the Netherlands, consisting of six different sites interconnected by SURF's optical network. The purpose of the network is to experiment with novel inter-domain network functions and emerging internet architectures, in particular to improve the transparency, accountability, and controllability of the Internet and future networks. We provide an overview of the testbed's set-up, examples of how we have used it, and our lessons learned.
