ARPANET and successors: open architecture networking
1970s: universities and other DoD contractors connect
packets rather than circuits (note many of the names in
the articles were graduate students then)
1975: 100 sites and e-mail is changing how people collaborate
Late 1970s: New Packet Switching Protocol:
Transfer Control Protocol/Internet Protocol(TCP/IP)
1980: MILNET takes over military traffic
1980s: NSFNet links together NSF researcgers,
Internet protocols incorporated into (BSD) Unix, a widespread operating system
Late 1980s: NSFNet absorbs original ARPANET (for a US university to get NSF
funding for an Internet connection, that connection had to be made available to
all qualified users on campus, regardless of discipline
1995: Commercial backbones replace NSFNet backbone
Commercial Networks: AOL, Compuserve, etc.
