P4 (Programming Protocol-independent Packet Processors) Language
This second blog post gives an overview of P4 programming by illustrating some of the key concepts found in most P4 programs, from header declaration to packets deparsing.
ReadProgramming Protocol-independent Packet Processors (P4) is a domain-specific language for network devices, specifying how data plane devices (switches, NICs, routers, filters, etc.) process packets. P4 programs are designed to be implementation-independent: they can be compiled against many different types of execution machines such as general-purpose CPUs, FPGAs, system(s)-on-chip, network processors, and ASICs.
