P4 is an Apache-licensed open source language owned by P4.org, an independent nonprofit. Any company, university, or individual can join P4.org free and contribute to the language, compiler, and tools. Intel is one of over 100 members of P4.org, including companies from all across our industry, from AT&T to ZTE, and some of the world’s top universities. The P4.org Advisory Board consists of Amin Vahdat (Google), Jennifer Rexford (Princeton), Nate Foster (Cornell), Guru Parulkar (ONF), and Nick McKeown (Stanford/Intel). The language was designed by world experts in programming language design from Princeton, Cornell, Stanford, VMware, Intel, Microsoft, Xilinx, Barefoot, and Google. P4 is open source and owned by everyone. The language is carefully designed to be target independent and can be used to program any programmable forwarding device. So far, it has been used to program a variety of software and hardware switches and NICs from different sources. See P4.org for more details.
