Louis Pouzin (born 20 April 1931) is a French computer scientist. He designed a pioneering packet communications network, CYCLADES that was the first to implement the end-to-end principle, which became fundamental to the design of the Internet.
This network was the first actual implementation of the pure datagram model, initially conceived and described by Donald Davies, subsequently named by Halvor Bothner-By, and seen by Louis Pouzin as his personal invention. His work, and that of his colleagues Hubert Zimmerman and Gérard Le Lann, were acknowledged by Vinton Cerf as substantial contributions to the design of TCP/IP, the protocol suite used by the Internet.
