If you into networking or specifically P4 you should take a look at the recent P4 workshop presentations.
I mentioned P4, a data plane programming language the other day. I’ve linked to a good overview paper below if you are interested.
I’ve done a bit of research into P4 recently. Figuring out if the IP-[TCP/UDP] mono-culture is here stay is a long-term interest of mine and P4 is perhaps one way to break that mono-culture.
One of the use cases presented for P4 is in-band telemetry. None of this really requires P4 but it’s interesting to think about hardware driven implementations.
