UKLIGHT is a research network connecting UK toNetherLight (Amsterdam)StarLight (Chicago)

UKLIGHT is fully funded, out to tenderUK PoP at ULCC (London)Hope for 10G linksDue to start operation in Jan 2004

UKLIGHT is an opportunity any reasonable project which has needs not easily satisfied by the IP production network may apply to make use of itHPC remote compute and visualisationRadio AstronomyHEP Data transport……….see next section

Timescales

early 2004

pre-procurement activities

mid 2004 formal backbone procurement

early 2005

roll out new backbone

mid 2005 close SuperJANET4 backbone

mid 2003 requirements analysis

end 2005 end of initial term of SuperJANET4 contract with MCI (WorldCom)

late 2003

obtain funding authorizations

SuperJANET5 – a Hybrid Routed/Switched Network ?

The key concept is parallelism at the transmission level

Coarse grained paths/circuits– Multiple fibres– Multiple wavelengths

Finer grained multiplexed paths/circuits– Structuring each wavelength

Foundation infrastructure provides switched pathsThe ‘standard’ IP service would be provided over one or more sets of these pathsSpecific paths could be set up for and between e-Science and Research groups

ESLEA at UKLight 21

RouterRouter

ESLEA at UKLight 22

A possible set of services could be:Production IP service

– High reliability & availability

High capacity research & e-Science connections – network layers 3/2/1 as required

– Mutual protection from production traffic

Network R&D – potentially any or all of Layers 3/2/1– Sequestered from production network

Institutions would take the combination of services they required Integrated infrastructure – separate servicesFlexible architecture – enable integration, access and evolution

Super Janet 5 Planning is just starting

Currently there is little evidence to motivate an upgrade from 10 -> 100 Gbit/s as SJ4 is empty …

However there is a realisation that it may be a “Multi service network.”

There is about to be a “Research Needs” focused workshop (5/6 Nov)

HEP has submitted a large “requirements” survey as part of an e-Science requirements exercise
