- 18th century – Mechanical systems and Industrial
revolution
- 19th century – Steam engine
(1961-1972: Early packet-switching
principles)
- 1961: Kleinrock – queuing theory shows effectiveness of
packet-switching
- 1964: Baran – packet-switching in military networks
- 1967: ARPAnet – conceived by Advanced Research Projects
Agency
- 1969: first ARPAnet node operational
- 1972: ARPAnet demonstrated publicly
- NCP (Network
Control Protocol) first host-host protocol
-
first e-mail program
-
ARPAnet has 15 nodes
(1972-1980:
Internetworking, new and proprietary nets)
- 1970: ALOHAnet satellite network in Hawaii
- 1973: Metcalfe’s PhD thesis proposes Ethernet
- 1974: Cerf and Kahn – architecture for interconnecting
networks
- late70’s: proprietary architectures: DECnet, SNA, XNA
- late 70’s: switching fixed length packets (ATM
precursor)
- 1979: ARPAnet has 200 nodes
- 20th century – Information gathering, processing, and
distribution.
