History of Internet  3000 BC : Abacus  1642 : Pascal ’ s Calculator  1822 : Babbage ’ s Difference Engine  1945 : ENIAC  1969 : ARPANET  1974 : TCP  1981 : IP  1984 : Domain Name  1988 : Morris Worm, CERT  1991 : WWW  1998 : IPv6

Background of Internet  Background USA DoD built ARPANET for their military purpose TCP/IP developed Internet showed up based on TCP/IP Internet backbone network built by NSF (National Science Foundation) Commercial Internet service started (BARRNet, SURANet) ( ’ 93)  Network Type Data communication LAN WAN

Internet Protocol : Hourglass + ? + IP ?

New Internet needed!  Extending Internet! Computer + Computer PC + PC PC + Computer Home appliances, Game machine Car Industrial machines Every chip equipped with Internet functionality  Lack of quality, reliability and security  Lack of mobile supports  Lack of distributed computing supports

Root Servers

Mobile Communication : All-IP 1G2G 3G 4G All-IP Analog Voice Circuit Digital Voice Low speed Data Circuit Digital Voice Medium Speed Circuit Packet Digital Voice, Image High speed Packet (?)

Internet Future  Internet Users? Human to machine …  Peer-to-peer applications  Depletion of IP address : IPv6 introduced  Transition from underlying information network (phone, broadcasting) to Internet  Home network, Industrial network adopt Internet
