Discussion Meeting at the DTI Offices Jan 02

• Presentations given by senior members of
• STARLIGHT
• NETHERLIGHT
• Attendees included
• Many UK network research groups
• The e-science directorate
• Grid Network Team
• UKERNA
• SURFnet
• There was clear support for developing an optical
  switching research infrastructure
• Keywords Enthusiasm Collaboration NOT Conflict
• A statement of interest has been sent to the
  Director of e-science

Some Research Topics Discussed

• How to get specific e-science traffic in out of
  lambdas
• How to deal with lambdas at Internet Exchange
  Points
• How to deal with provisioning when several
  administrative domains are involved
• How to do fine-grain near real time Grid
  application lambda provisioning
• Resilience protection
• Multi-hop routing
• Multi-hop scheduling of lambdas
• Stability
• High throughput transports
• Keywords gt10Gbit Testbed Opt sw / X-connects
  WAN-MAN
• (Many parallels with the present discussions
  very welcome)

Demonstration Projects

• Optical projects in other countries include
• tele-immersion, multimedia, tele-teaching,
  distributed tera-computing
• Real-time streaming of data from Radio telescopes
  to the correlator Jodrell Bank JIVE
  e-Merlin 40Gbit
• High bandwidth visualisation projects
• Particle Physics could benefit from piloting the
  use of switched lambdas on demand for delivery of
  very large datasets
• There is UK involvement in iGrid2002 projects
• DataTAG
• DataGrid
• Radio Astronomy e-correlation
