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 Foundati
on)• Commercial Internet service started (BARRNet, SURANet) (’93)
Network Type• Data communication• LAN• WAN
New Internet needed!
Extending Internet!• Computer + Computer• PC + PC• PC + Computer• Home appliances, Game machine• Car• Industrial machines• Every chip equipped with Internet

Grid NOC (1/4)Grid NOC (1/4)
Provides reliable network service to develop and
experiment Grid applications
Supports high performance network
technologies for Grid application developers
Plays a role of interface between Grid projects
Builds and operates Grid NOC
Grid NOC (2/4)Grid NOC (2/4)
Grid Developers
Need Grid network supportsfor Grid development!-> Write an application forGrid network supports
2. Application acceptance
1) How much bandwidth needed?2) Most efficient routing techniques?3) What kind of protocols needed? (IPv4, IPv6,
Multicast?)4) Prediction of traffic quantity and determination of
bandwidth5) Need any cooperation with other networks?
Grid NOC
3. Examination
1. Send in an application to Grid NOC
4. Discussion with Grid developers
