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

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
