TERENA Networking Conference - 9th June 2004
UKLight 3
Background
• Towards optical networking• International activities
• StarLight – evolved from Startap• International exchange point – “bring your lambdas”
• Joined by NetherLight• “Lambda” workshops
• Sept 2001, 2002, 2003, (2004 – UK)• TERENA
• 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
• Internal meetings and papers during 2002• UKLight bid to JCSR – Nov 2002• Funding approved March /April 2003• 29 months & we are here…

UKLight 4
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
TERENA Networking Conference - 9th June 2004
UKLight 5
Potential early adopters
• 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
TERENA Networking Conference - 9th June 2004
UKLight 6
• ESLEA partners• Peter Clarke co-ordinated
• ULMAS – monitoring at many scales• Lionel Sacks & colleagues
• Others are interested…
Projects approved
TERENA Networking Conference - 9th June 2004
UKLight 7
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…
TERENA Networking Conference - 9th June 2004
UKLight 8
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
TERENA Networking Conference - 9th June 2004
UKLight 9
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

Model for Extension of the SuperJANET Development Network
TERENA Networking Conference - 9th June 2004
UKLight 13
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…
TERENA Networking Conference - 9th June 2004
UKLight 14
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

• 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

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
TERENA Networking Conference - 9th June 2004
UKLight 29
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

Flexible Transmission Platform
Design characteristics• Transmission channels configured and managed at our control
• Scalable to higher bandwidth at controllable cost
• A range of options exist
telco. provides bandwidth services
telco. provides “wavelength” services
telco. manages fibre and the light only
UKERNA leases fibre and also lights it
UKERNA owns, manages and lights fibre
