P4 is a programming language designed to allow programming of packet forwarding dataplanes. In contrast to a general purpose language such as C or python, P4 is a domain-specific language with a number of constructs optimized around network data forwarding (wikipedia). https://en.wikipedia.org/wiki/P4_(programming_language)

P4 has documentation that can be read from their github page: https://github.com/p4lang

This is a softswitch (Software Switch à la OVS) written with the p4 language (http://p4.org/code/).

This project is intended to be used with https://github.com/sniggel/vagrant-p4
