We have been developing P4 programs (a language to program programmable data planes, PDPs) to run NC on these devices, but it is still work-in-progress. We are currently evaluating a first prototype in software, and we are now preparing the next stage: to run this in our hardware platforms (a SmartNIC based on NetFPGA, and a Barefoot Tofino switch). We should thus have something to share in the near future -- not necessarily in the next meeting, but hopefully soon.

We have been collaborating with a couple of other research groups around this topic, but besides us my feeling is that there is indeed interest in the community around this topic -- and generally on the opportunity PDPs offer to experiment new networking architectures at scale. For instance, last week I was in Dagstuhl organising a seminar on programmable data planes ( <> — a report will be out soon, and maybe a CCR editorial too), and several people seemed interested in this line of work.
