The Dataplane Acceleration Developer Day Europe 2017, organised by Open-NFP, will take place on 7 June. The day will be hosted by SURFnet. In a hands-on workshop you will learn step-by-step how to programme a SMART NIC using P4, which will allow you to add new functionality to the network. P4 is a domain-specific language for network protocols. P4 allows you to experiment with new network protocols. P4 also has powerful applications in the field of network monitoring.
