Why AMS-IX at Science Park Amsterdam?

• Spin-off from international scientific projects
• Our scientists need high-bandwidth networks
• Early involvement in internet developments (1980
  )

A brief history of networking at science park
Adam

• 1980 First connection to CERN 1200 Baud modem
  by telephone

• 1982 Eunet becomes into existing (CWI at WTCW)

• 1983 ARPAnet in the USA switches to employ TCP/IP

• 1985 The campus network at WTCW is established
  (10 Mbps shared)
• elelectronic mail and Usenet news are
  relayed (CWI again)

• 1986 SURFnet is started to establish an academic
  research network in NL
• The .nl domain is registered.

• 1990 TCP/IP is globally accepted as the
  network protocol
• The predecessor of the AMS-IX is
  established at WTCW

• 1991 The private NIKHEF-CERN line is
  decommissioned

• 1992 The World Wide Web comes into action
  (invented at CERN!)

• 1994 Informal start Internet Exchange
• 1997 The AMS-IX is started as a neutral Internet
  traffic exchange

• Now The AMS-IX is one of the largest
• Internet exchanges in
  the world

Amsterdam Internet Exchange (AMS-IX)

• An Internet Exchange is a neutral and independent
  place for Internet Service Providers to exchange
  internet traffic
• AMS-IX is an association (vereniging)
• Execute board (5 elected members)
• AMS-IX BV responsible for daily operations
• AMS-IX NOC responsible for technical operations

19
Amsterdam Internet Exchange (AMS-IX)
Two type of AMS-IX members

• Telecom operators (carriers) e.g.
• KPN Telecom Versatel
• MCI BT Ignite (Telfort)
• Colt Telecom Global Crossing

• Internet Service Providers (ISPs) e.g.
• Xs4all Wanadoo
• Planet Online TeleDanmark
• Internet Access Eindhoven Tiscali
• Internet admin organizations
• RIPE NCC
• NL Domain Registration

Amsterdam Internet Exchange (AMS-IX)

• Statistics (October 2005)
• 230 members
• 398 connected ports
• 30 carriers supply bandwidth capacity
• Aggregate volume of all connections 21000
  TB/month
• equals to an average bit rate of 75 Gbit/sec
• equivalent of to 500.000 e-mails/sec !
