  4. AbMAN SuperJANET R&D Network UHI Network Clydenet FaTMAN EaStMAN NNW C&NL MAN • Parallel R&D Network • Ethernet infrastructure • 1 – 10 Gbit/s • Can connect any UK institute in principle • Currently connects 3 sites Glasgow Edinburgh NorMAN North Wales MAN YHMAN Warrington Leeds EMMAN MidMAN London EastNet Reading RAL TVN Kentish MAN External Links Bristol Portsmouth Northern Ireland LMN External Links South Wales MAN SWERN LeNSE US –Japan N+N

  5. UKLIGHT is…. • UK Joining Global optical testbed • R&D links to NL and USA • 10 Gbit/s • Available for leading edge network projects • Designed to pilot new ways of networking • Motivated on “lightpath” switching below IP layer US –Japan N+N

  6. UKLight – showing connections to selected International peer facilities UK Researchers SuperJANET R&D Network UKLightLondon CA*net StarLightChicago 10Gb/s 2.5Gb/s 10Gb/s Abilene CERN 10Gb/s 10Gb/s 10Gb/s NetherLightAmsterdam CzechLight Local Research Equipment GEANT International Point-of-Access US –Japan N+N

  7. UKLIGHT Projects already suggested • Particle Physics • Radio Astronomy • HPC interconnection and computational steering • Medical Diagnostic Imaging • UKLIGHT Open Meeting • What is the International ‘Light’ infrastructure • How projects might use it • 3rd November • Will publicise through UKERNA & NeSC web sites • If anyone wants to go let me know !!!!!!!! US –Japan N+N

  8. Router Router SuperJANET 5 .. The Next Generation UK Network .. May look like this.. • Multi service • Routed IP • Layer 2 • ??? Layer 1 • Start 2005 US –Japan N+N

  9. The Grid and the Network • The UK National Network Infrastructure • A summary of E-Science supported Network projects in the UK • Protocols • Middleware for network services US –Japan N+N

  21. Summary Activities in the UK are ensuring that the network is ready to serve the Grid at all levels • Infrastructure • Current 10 Gbit/s network - Future “multi layer” hybrid network • UKLIGHT optical networking node • Protocols • IPv6 community and network infrastructure • Advanced TCP and non-TCP transport protocol work • QoS • Services & Middleware • Performance measurement and publication to Grid Information services • Diagnostics for Grid operations • Resource allocation and reservation Middleware • EGEE Responsibility Many opportunities for UK –Japan Joint Network Activities using research network infrastructure US –Japan N+N

  23. GridPP Testbed • All HEP experiment sites are part of Gavin’s “green dot” map. • At least a Globus gatekeeper was running at some point. • In almost all cases this is actually an EDG gatekeeper - ie with extra functionality. US –Japan N+N

  24. GridPP Testbed • Uses Resource Broker at IC, MDS at RAL and VO at Manchester. Yesterday’s snapshot: Birmingham 2 cpus Bristol 3 Cambridge 16 IC 16 (+ 80 BaBar) Liverpool 2 Manchester 8 (+ 60 DZero/Atlas) Oxford 1 RAL 6 (+Tier1/A) UCL 2 • Result of: • Core team in UK working within EDG • Bi-weekly operational phone call US –Japan N+N

  25. EDG testbed EDG sw installed at more than 40 sites Application testbed: More than 1000 CPUs 5 Terabyte of storage US –Japan N+N

  26. EDG Testbed • Snapshot for EU review: CERN 59 + 20 nl: Nikhef 140 fr: CC Lyon 22? + 74? + 409? fr: Polytechnique/LLR 6 it: CNAF Bologna 48 it: Padova 11 it: Legnaro 48 uk: IC 16 + 80 uk: Liverpool 2 uk: Manchester 8 + 60 uk: Oxford 1 uk: RAL 6 (so we’re doing ok internationally) US –Japan N+N
