Hubert Zimmermann
Hubert Zimmermann (15 November 1941 – 9 November 2012) was a French software engineer and a pioneer of computer networking. Biography Zimmermann was educated at École Polytechnique and École Nationale Supérieure des Télécommunications. His career began at Institut National de Recherche en Informatique et Automatique (INRIA) in Rocquencourt from 1972 through 1979, where he led research into what became ChorusOS series of distributed operating systems. He participated in the International Networking Working Group from 1972, initially chaired by Vint Cerf. He was acknowledged by Bob Kahn and Cerf in their seminal 1974 paper on internetworking, "A Protocol for Packet Network Intercommunication". In 1977, he was an early member of the International Organization for Standardization as it developed the Open Systems Interconnection protocols. He then worked for France Télécom in 1980 through 1986. He developed and promoted the OSI reference model which became a popular way t ...

Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications pro ...

Chorus Systèmes SA
Chorus Systèmes SA was a French software company that existed from 1986 to 1997, that was created to commercialise research work done at the Institut national de recherche en informatique et en automatique (INRIA). Its primary product was the Chorus distributed microkernel operating system, created at a time when microkernel technology was thought to have great promise for the future of operating systems. As such Chorus was in the middle of many strategic partnerships regarding Unix and related systems. The firm was acquired by Sun Microsystems in 1997. Origins The Chorus distributed operating system research project began at the French Institut national de recherche en informatique et en automatique (INRIA) in 1979. At pp. 306, 308, 309, 366. The project was begun by Hubert Zimmerman, a pioneer of networked computing who devised the OSI reference model which became a popular way to describe network protocols.

Rémi Després
Rémi Després (born January 16, 1943) is a French engineer and entrepreneur known for his contributions on data networking. Education In 1961–1963, Rémi Després attended École Polytechnique of Paris, of which he holds an Engineer degree. At UC Berkeley, he received a master's degree in 1967, and a Ph.D degree in 1969, both in the EECS Department. Career From 1963 to 1971 at CNET and UC Berkeley, he specialized in programming languages and time-sharing operating systems. From 1971 to 1980, Rémi Després was in charge of R&D of the French PTT on packet switching. He was one of the leading "innovators who worked across the boundaries of computers and communications" in the 1970s. As such, he introduced the concept of graceful "saturated operation", which was referenced by Bob Kahn and Vint Cerf in their seminal 1974 paper on internetworking, ''"A Protocol for Packet Network Intercommunication".''

Louis Pouzin
Louis Pouzin (April 20, 1931 in Chantenay-Saint-Imbert, Nièvre, France) is a French computer scientist. He designed an early packet communications network, CYCLADES. 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. Biography He studied at the École Polytechnique from 1950 to 1952. Having participated in the design of the Compatible Time-Sharing System (CTSS) at MIT, Pouzin wrote a program for it called RUNCOM around 1963–64. RUNCOM permitted the execution of commands contained within a folder and can be considered the ancestor of the command-line interface and shell scripts. Pouzin was the one who coin ...

Internet In France
Internet in France has been available to the general public since 1994, but widespread Internet use did not take off until the mid-2000s. As of 31 December 2014, France had 26 million Internet broadband and high-speed connections on fixed networks. In 2014, 80.7% of French households (22.5 million households) had Internet access (47 million users in January 2015, according to Médiamétrie), while 19.3% did not (5.4 million households, out of a total of 27.8 million households). In 2014, 82% of French people aged 12 and over had Internet access at home (even though only 77% used it), and 64% of French people aged 12 years and older connected daily to the Internet from home. Considering all connections locations (not only the home), 83% of French people were Internet users. In metropolitan France, intense competition between Internet service providers has led to the introduction of moderately-priced high speed ADSL up to 28 Mbit/s ( ATM), VDSL2 up to 100 Mbit/s, and FTTX up to 1 Gbi ...

History Of The Internet
The history of the Internet has its origin in information theory and the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France. Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. J. C. R. Licklider developed the idea of a universal network at the Information Processing Techniques Office (IPTO) of the United States Department of Defense (DoD) Advanced Research Projects Agency (ARPA). Independently, Paul Baran at the RAND Corporation proposed a distributed network based on data in message blocks in the early 1960s, and Donald Davies conceived o ...

Gérard Le Lann
Gérard Le Lann is a French computer scientist at INRIA. In networking, he worked on the project CYCLADES with an intermediate stint on the Arpanet team. Life and career Gérard Le Lann's career has been summarized in 1975 as follows: ::Gérard Le Lann holds French degrees, a M.S. in Applied Mathematics, an Engineering Degree in Computer Science (both from the University of Toulouse) and a Ph.D in Computer Science (University of Rennes).
