Re-bonsoir,

Pour ceux qui veulent avoir des lumières sur les systèmes DARPA précurseurs 
de l'Internet, je conseille (pour une fois !) ce site :

On peut y lire en particulier :

ARPANET. The ARPANET, which is a major component of the NSFnet [National
Science Foundation Network], began in 1969 as an R&D project managed by DARPA
[Dept. of Defense Advanced Research Projects Agency]. ARPANET was an experiment
in resource sharing, and provided survivable (multiply connected), high
bandwidth (56 Kilobits per second) communications links between major existing
computational resources and computer users in academic, industrial, and
government research laboratories.  ARPANET is managed and funded by by the DCA
[Defense Communications Agency] with user services provided by a network
information center at SRI International.
      ARPANET served as a test for the development of advanced network 
protocols
including the TCP-IP protocol suite introduced in 1981.  TCP-IP and
particularly IP, the internet protocol, introduced the idea of inter-
networking -- allowing networks of different technologies and connection
protocols to be linked together while providing a unified internetwork
addressing scheme and a common set of transport of application protocols. This
development allowed networks of computers and workstations to be connected to
the ARPANET, rather than just single-host computers.  TCP-IP remain the most
available and advanced, non-vendor-specific, networking protocols and have
strongly influenced the current international standards of activity.  TCP-IP
provide a variety of application services, including remote logon (Telnet),
file transfer (FTP), and electronic mail (SMTP and RFC822).


Bien cordialement,
