Overview

• Background• What is UKLight ?• Architecture• UK National Access• Governance• Status• Projects• Futures


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…


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


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

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

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
