P4: A high-level language for programming protocol-independent packet processors

P4 is a high-level language for configuring network switches and routers, with the overarching goal of improving current Software-Defined Networking (SDN) in three ways: (1) Reconfigurability in the way that switches process packets after deployment; (2) Protocol independence, allowing switches to be designed as a blank slate with no specific network protocol support; and (3) Target independence: packet-processing functionality that is completely independent of the underlying switch hardware specifics.
