This past week I had the pleasure of presenting at CNERT 2015: "Computer and Networking Experimental Research using Testbeds", which was held in conjunction with ICDCS: "International Conference on Distributed Computing Systems". Sponsored by NSF-GENI, CNERT's aim is to advance experimental research and testbed technologies. Presenters spoke about technologies utilizing a wide range of testbeds including GENI, DeterLab, Emulab, and FIRE federated testbeds.
