    Invention and Research

    The invention of Ethernet is based on the principles of packet switching, the development of both the ARPANET and ALOHANet, and it both impacted and was influenced by the principles underlying the interconnection of networks.

  • Xerox PARC Established

    Xerox PARC Established
  • ALOHAnet

  • Ethernet@0

    • On May 22, 1973, Bob Metcalfe at Xerox PARC documented the invention of Ethernet in a Memo, which described communication across different "ethers" - including cable, telephone, and radio - building on the ALOHAnet protocol.
    • Bob Metcalfe, David Boggs, and Tat Lam built the first Ethernet prototype at 2.94 Mbps

    DIX Formed
    Bob Metcalfe persuaded Gordon Bell at DEC, David Liddle at Xerox and Phil Kaufman at Intel to jointly develop an Ethernet specification based on X-Wire. This group was called DIX
  • Period: to


    The creation of the Ethernet standard involved collaboration between DEC, Intel and Xerox, and then ratification by IEEE/ISO as IEEE 802.3.
  • Period: to


    Simultaneously to the creation of the standard, the commercialization of Ethernet began by 3Com and Ungermann-Bass, and then quickly followed by many startups.
