Overview

• Background• What is UKLight• Architecture• UK National Access• Governance• Status


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 bandwidthdelay 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


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


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
