3 Particle physics at NIKHEF NIKHEF participates in international collaborations Particle physics detectors produce large data sets Now: building the LHC Computing Grid LCG DESY in Hamburg CERN in Geneva Fermilab near Chicago

4 ATLAS detector: data production One of the four LHC detectors 40 MHz (40 TB/sec) level 1 - special hardware 75 KHz (75 GB/sec) nline system ulti-level trigger lter out background duce data volume level 2 - embedded processors level 3 - PCs 5 KHz (5 GB/sec) 100 Hz (100 MB/sec) data recording & offline analysis

5 ATLAS detector: data production

6 ATLAS detector: data production ATLAS: 200 miljoen detektor elementen

9 Data distributie (using the internet) ada S taipei

10 LCG: a distributed computer and storage grid connected by high-bandwidth networks

11 Grid projects Research, development, deployment Participation NIKHEF in European grid project: E-GEE National grid project: VL-E Industrial partnerships: IBM, LogicaCMG, InTouch. UvA, SARA, SURFnet, etc

12 Amsterdam Internet Exchange AMS-IX

13 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 ) Sciencepark Amsterdam x x x

14 Internet exchange Internet knooppunt Internet infrastructuur

15 A brief history of networking at science park A dam 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

16 Internet Exchange UUnet ISP 2 ISP 1 Chello Tiscali ISP 3 ISP 6 ISP 4 = Internet Service Provider ISP 5 does not scale up

17 Internet Exchange ISP 2 ISP 1 ISP 3 Internet Exchange ISP 6 ISP 4 Internet Service Provider Telecom operators (carriers) upstream connection peering connection ISP 5

18 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 (ISP s) e.g. Xs4all Wanadoo Planet Online TeleDanmark Internet Access Eindhoven Tiscali Internet admin organizations RIPE NCC NL Domain Registration

20 Multiple carriers - multiple cables

21 Amsterdam Internet Exchange (AMS-IX) Statistics (October 2005) : 230 members 398 connected ports 30 carriers supply bandwidth capacity Aggregate volume of all connections: TB/month equals to an average bit rate of 75 Gbit/sec [ equivalent of to s/sec! ]

22 Aggregate volume of all ISP s connected to AMS-IX ourly graph ctober 22, 2004 aximum at 9:00 PM: 05 Gbit/sec inimum at 6:00 AM: 5 Gbit/sec monthly graph Average volume: Jul 2004: 23 Gbit/sec Oct 2005: 70 Gbit/sec

23 AMS-IX housing locations 1994 WTCW: SARA NIKHEF 2000/2001: TeleCity (Z.O.) Global Switch (W.) sciencepark

25 Amsterdam Internet Exchange (AMS-IX) The heart of the internet exchange: Foundry Networks gigabit switches

26 Euro-IX Affiliated Internet Exchange Points

27 More info:

28 NIKHEF AMS-X housing location NIKHEF housing services include: Rack space rental Power feed (no break), cooling Cabling infrastructure Access control Fire protection Intelligent hands and feet during regular working hours NIKHEF housing services does not include: Equipment installation, configuration, maintenance (customers) Network operation (AMS-IX BV)

29 What happens in case of failures? Problems. power outage broken central switches cabling problems Solutions No-break installations Internet topology offers redundancy (rerouting) Large ISP s connected to more then one exchange Cable feed from two directions

30 In case of a power failure Installation of the diesel generator on October 16 th 2002
