Going North (Australia Japan Cable) Where it gets us to: Japan (optionally Guam) From Japan to: North Asia South East Asia US From Guam: Cable interconnect opportunities 18 Copyright AARNet 2005 • We have attractive pricing on this cable system • Need to avoid biting off more than we can chew • Logistics dictate that TEIN2 and additional commodity are higher priorities • As soon as TEIN2 is bedded down, should progress with AJC options • Part of strategy yet to be implemented “Big Science” projects driving networks • Billion dollar globally funded projects Massive data transfer needs • 19 Copyright AARNet 2005 Large Hadron Collider – Coming on-stream in 2007 – Particle collisions generating terabytes/second of “raw” data at a single, central, well-connected site – Need to transfer data to global “tier 1” sites. A tier 1 site must have a 10Gbps path to CERN – Tier 1 sites need to ensure gigabit capacity to the Tier2 sites they serve Square Kilometre Array – Coming on-stream in 2010? – Greater data generator than LHC – Up to 125 sites at remote locations, data need to be brought together for correlation – Can’t determine “noise” prior to correlation – Many logistic issues to be addressed From very small to very big 20 Copyright AARNet 2005 Scientists and Network Engineers coming together • HEP community and R&E network community have figured out mechanisms for interaction – probably because HEP is pushing network boundaries • eg the ICFA workshops on HEP, Grid and the Global Digital Divide bring together scientists, network engineers and decision makers – and achieve results • http://agenda.cern.ch/List.php 21 Copyright AARNet 2005 What’s been achieved so far 22 Copyright AARNet 2005 A new generation of real-time Grid systems is emerging - support worldwide data analysis by the physics community Leading role of HEP in developing new systems and paradigms for data intensive science Transformed view and theoretical understanding of TCP as an efficient, scalable protocol with a wide field of use Efficient standalone and shared use of 10 Gbps paths of virtually unlimited length; progress towards 100 Gbps networking Emergence of a new generation of “hybrid” packet- and circuit- switched networks LHC data (simplified) 1 Megabyte (1MB) A digital photo Per experiment 40 million collisions per second • After filtering, 100 collisions of interest per second • A Megabyte of digitised information for each collision = recording rate of 100 Megabytes/sec • 1 billion collisions recorded = 1 Petabyte/year CMS 23 Copyright AARNet 2005 LHCb ATLAS 1 Gigabyte (1GB) = 1000MB A DVD movie 1 Terabyte (1TB) = 1000GB World annual book production 1 Petabyte (1PB) = 1000TB 10% of the annual production by LHC experiments 1 Exabyte (1EB) = 1000 PB World annual information production ALICE LHC Computing Hierarchy CERN/Outside Resource Ratio ~1:2 Tier0/( Tier1)/( Tier2) ~1:1:1 ~PByte/sec ~100-1500 MBytes/sec Online System Experiment CERN Center PBs of Disk; Tape Robot Tier 0 +1 Tier 1 ~2.5-10 Gbps IN2P3 Center INFN Center RAL Center FNAL Center 2.5-10 Gbps ~2.5-10 Gbps Tier 3 Tier 2 Institute Institute Physics data cache 24 Workstations Copyright AARNet 2005 Institute Tier2 Center Tier2 Center Tier2 Center Tier2 Center Tier2 Center Institute 0.1 to 10 Gbps Tier 4 Tens of Petabytes by 2007-8.

Lightweight users, browsing, mailing, home use. Who need full Internet routing, one to many; 2. Business applications, multicast, streaming, VPN’s, mostly LAN. Who need VPN services and full Internet routing, several to several + uplink; and 3. Scientific applications, distributed data processing, all sorts of grids. Need for very fat pipes, limited multiple Virtual Organizations, few to few, peer to peer.
