Background
• International activities
• StarLight – evolved from Startap
• International exchange point
• Joined by NetherLight
• “Lambda” workshops
• Sept 2001, 2002, 2003, (2004 – UK)
• Terena
• Initiative attempted with Flag Telecom during 2002
• UK activities have evolved from these over last 2
years or so
• Internal meetings and papers during 2002
• UKLight bid to JCSR – Nov 2002
• Funding approved March /April 2003

What is UKLight ?
• 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

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

Network Engineering
• Hybrid network: development & integration
• packet-over-channel with dynamic channel access
and configuration: GMPLS or bespoke
agent/broker
• end-to-end access to channels for R&D and
specialised hard-real-time applications
• High throughput transport development in a high
bandwidthdelay environment
• ESLEA partners – Peter Clarke

Funding
• Funding – SRIF - £6.5M total
• From HEFCE (Higher Education Funding Council for
England)
• Via JISC (Joint Information Systems Committee)
• 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

• 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
• May be relevant for future incarnations of JANET

Governance and use by Projects
• Governance
• Steering Committee – JISC established
• covers policy and funding issues
• Hugh Pilcher-Clayton (EPSRC) will chair
• International representatives
– Bill St Arnaud and David Williams
• Technical Advisory group – UKERNA established
• operations and project-feasibility assessment
• David Hutchison (Lancaster University) will chair
• Project use
• Projects funded by Research Council & other programmes
• Central funding covers equipment interface at backbone
edge

Future Expansion
• Build to meet requirements of approved projects
• Phase 2 likely candidates
• CLRC – RAL (& DL) (and backbone site at Reading)
• Lancaster
• Leeds - White Rose Grid (and backbone site at Leeds)
• Phase 3 – still very speculative
• Remaining budget would allow equipping access to about
half of the Regional Networks)
• Commit funds during 2004
• Use budget to give projects working time during 2005
• Beyond this we’re into SuperJANET5 !
• Incorporate these concepts from ground up
• Flexible transmission platform
• Fibre / wavelength service based
