Some thoughts on current and future experimentation needs

Experimental networking research needs have probably not changed much from the time the NSF Workshop Network Research Testbeds took place in 20021. So, it would be worth revisiting the outcomes of that workshop with the current context. In this sense, this paper tries to do this for some of the items dealt with in the report generated (e.g., Multi-user experimental facilities, federated testbeds, network research kits) and to revisit some of the experimentation needs in the light of recent developments on network softwarization. In fact, virtualization was already identified as a relevant trend. However, developments at that time were far from those recently generated.© 2019 IEEE. Personal use of this material is permitted.
