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

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
