• Initiative attempted with Flag Telecom during 2002
• Interest within Grid Network Team – UK e-Science programme
• UK activities have evolved from these over last 2+ years
•

What is UKLight ?
• Facility to provide national and international “bandwidth
channels” for use by research and e-Science projects
• Cross-discipline initiative
• JANET community
• Network research
• e-Science applications
• optical (photonic) communications research
• UKERNA – manage and develop JANET
• supporting the community
• advanced service-network development
• Components:
• UK point-of-access and links to international facilities
• UK national photonics facility/infrastructure
• UK national R&D network infrastructure
• extending access within JANET

• Particle Physics
• high performance data transfer
• Radio Astronomy
• very long baseline interferometry
(near-real-time data transfer)
• Distributed HPC & visualization
• Remote cancer diagnosis
• federated databases & visualization

Funding
• Funding – SRIF - £6.5M total
• From HEFCE (Higher Education Funding Council for
England)
• Via JISC (Joint Information Systems Committee)
• Sub-committee for Support of Research (JCSR)
• International Point of Access
• Circuits, equipment, housing, NMS, staff…
• UK Access and photonics infrastructure
• Equipment, housing…

What is UKLight ? –
Infrastructure perspective
• Infrastructure to support the UK part of an International
facility (GLIF – Global Lambda Integrated Facility) for
Network and Advanced applications R&D
• Eg international Gigabit ethernet ‘channels’
• UKLight will apply to join Translight and contribute
“lambdas”
• Implemented with:
• Telco Wavelength services
• Transmission equipment providing Multiplexed channels
(SDH) to carry Gigabit ethernet
• Ethernet switch/es

UKLight components
• International Point of Access in London
• Wavelength services to
• StarLight (Chicago)
• NetherLight (Amsterdam)
• Internal UK access via extended JANET
development Network
• Dark-Fibre facility for photonics community

Development Network
Extension Model
• Uncommitted backbone bandwidth in MCI
contract for SuperJANET4
• 10G for current production backbone
• Additional 10G available but uncommitted
• Parallel to existing core
• Upgrades to Regional Network access points also
included
• Presented as SDH
• not dark fibre …
• But it still opens up interesting options…

Principles
• Use SDH multiplexers to partition this bandwidth
on a link by link basis
• e.g. 10Gb/s  4 x 2.5Gb/s
• Configure end-to-end paths using the partitioned
links - channels
• Projects will run VLANS / IP etc. over their
channels
• Operating transmission equipment, will bring
telco style provisioning issues
• Links to concepts for SuperJANET5

UKLight Governance
• Steering Committee (SC) – JISC established
• covers policy and funding issues
• Hugh Pilcher-Clayton (EPSRC) will chair
• International representatives
• Bill St Arnaud (Canarie) and David Williams (CERN/TERENA)
• Community representation
• Peter Clarke (UCL), Dave Deroure (Southampton), Brian
Gilmour (Edinburgh), David Hutchison (Lancaster), Guy Rickett
(PPARC), David Salmon (UKERNA), Lesley Thompson (EPSRC)
• Plus JISC & UKERNA attendees
• Technical Advisory Group (TAG) – UKERNA established
• operations and project-feasibility assessment
• David Hutchison (Lancaster University) will chair
• Community representation
• Tim Chown (Southampton), Lionel Sacks UCL), Dimitra
Simeonidou (Essex), Ian White (Cambridge)
• John Graham (ULCC) – UKLight engineer
• David Salmon (UKERNA)

Use by projects
• Projects expected to be funded by Research Council or
other programmes
• Central funding covers equipment interface at backbone
edge
• Projects discuss options with UKLight project manager &
submit written connection proposal
• UKLight TAG will assess feasibility & provide a report
• Use as part of research proposal
• Existing projects can also make a case to connect
• Will need endorsement by original funding programme
• In some cases may need to consult the UKLight steering
committee

Future Expansion
• Build to meet requirements of approved projects
• Phase 3 – still speculative
• Remaining budget would allow equipping access to about
half of the Regional Networks)
• JISC/Research Council will call for expressions of interest to
connect to UKLight
• Steering Committee will prioritise responses
• Commit funds during 2004
• Use budget to give projects working time during 2005
• Beyond this leads into SuperJANET5 !
• Incorporate these concepts from ground up
• Flexible transmission platform
• Fibre / wavelength service based
