History
1961-1972 - Early Packet-switching Principles
- 1961 - Kleinrock - Queuing theory shows effectiveness of packet switching.
- 1964 - Baran - Packet-switching in military nets.
- 1967 - ARPAnet conceived by Advanced Research Projects Agency.
- 1969 - First ARPAnet node operational.
- 1972 - ARPAnet public demo.
- NCP - Network control protocol is the first host-host protocol.
- First e-mail program.
- ARPAnet has 15 nodes.
1972-1980 - Internet Working, New & Proprietary Nets
- 1970 - ALOHAnet satellite network in Hawaii.
- 1974 - Cerf & Kahn - Architectures for interconnecting networks.
- Minimalism, autonomy - no internal changes required to interconnect networks.
- Best effort service model.
- Stateless routing.
- Decentralised control
- 1976 - Ethernet at Xerox PARC.
- Late 70s - Proprietary architectures: DECnet, SNA, XNA.
- 1979 - ARPAnet has 200 nodes.
1980-1990 - New Protocols, A Proliferation of Networks
- 1983 - Deployment of TCP/IP
- 1982 - SMTP e-mail protocol defines.
- 1983 - DNS defines for name-to-IP-address translation.
- 1985 - FTP protocol defined.
- 1988 - TCP congestion control.
The french government gives free network access devices to access the Minitel network.
1990-2000 - Commercialisation, The Web, New Applications
- Early 1990s - ARPAnet decommissioned.
- 1991 - NSF lifts restrictions on commercial use of NSFnet (decommissioned 1995).
- Early 1990s - The Web
- Hypertext (Bush - 1945, Nelson - 1960s)
- HTML, HTTP (Berners-Lee)
- 1994 - Mosaic, later Netscape.
- Late 1990s - Commercialisation of the web.
- Late 1990s-200s:
- More killer apps - Instant messaging, P2P file sharing.
- Network security to forefront.
- 50 millions hosts, 100 million users.
- Backbone links running at Gbps
2005-Present - More applications, greater proliferation.
- 18 billion connected device.
- Aggressive deployment of broadband.
- Online social networks.
- Service providers (Google, FB…) create their own networks.
- Enterprises run their services in the cloud.
