• 1972: ARPAnet demonstrated publicly
•            NCP (Network Control Protocol) first host-host protocol

• 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
