Janet – e-Infrastructure networking

•£26M With HEFCE

Breakdown

•£10M Contribution to Janet6 backbone

•£12M Network provision within “classic” Janet community, including key locations which may need additional fibre access

•£4M “Industry connection”

e-Infrastructure Strategic Sites•Potential fibre / capacity requirements•Work with organisations to understand requirements•Build cases for provision

•If approved, integrate provision with deployment of Janet6

Gathering strategic requirements•Immediate focus on sites mentioned..

•Generic approach– Senior research management– Senior infrastructure management

•Strategic view – 5+ years•Quantitative•Patterns of use

– Locations, data volumes -> net capacities•Challenging !

Patterns of use• Data movement – working patterns– How much – data volume ?

• Beware Bytes vs. bits !– How quickly ?– How often ?– Where to ?– National & International

• Network engineers need bit-rates !• Working with research communities to

understand emerging/evolving requirements

Expectations ?• Janet provision–meet acute needs in shorter term– broader provision within Janet6–mechanisms• IP capacity to host organisation• some point to point services

e-Infrastructure projects funded•HPC

– 5 regional consortia– National facility – Hector / Archer– Dirac

Some implications

14

Throughput challenges

• Infrastructures can deliver very high capacities

• Realising high-throughput end-to-end will take some effort

• Can’t just take systems “out of the box” and expect to get full line-rate data-transfers

• This needs to be communicated & understood more widely

• Janet & NREN community needs to work more closely with research communities to understand and solve issues. 1

5

Achievable Throughput• What is realistic ?– Challenge: 1Gbit/s, 24hr ~= 10TBytes

• Holistic approach– End systems - Hardware & Software - Both

ends !– Local networks– Wide area networks

• Highlight successful examples– Technical case studies

• Janet role ?– Co-ordination/collaboration– Advice & troubleshooting support ?

Network structure implications ?• Large research communities• International/global overlays or private

networks• Particle physics - LHC OPN (LHCONE)• Radio Astronomy – eVLBI, LOFAR, (SKA...)• Future – Bioinformatics ?? ELIXIR• Campus implications ?

point to point services (lightpaths)more complex multi-homing – routing/switching

issues

Industry ?

• Existing Janet policy– Supporting collaborative R&D– Business and Community Engagement

(BCE)• Evolution - more needed ?• e-Infrastructure– “Open and accessible Janet”

Connecting Industry – meaning ?

• Network connections ?• Access to community systems &

resources connected to Janet ?• Access to Janet community

knowledge & expertise ?–Mix of all three...

• BIS & HPC Consortia views ?

Conclusion & seed discussion issues ?

• Throughput performance– Your views on what Janet should be

doing ?• Services multiplying– Campus issues & implications– Advice or information required ?

• Other points ?– Janet supporting research
