What is required...

• Optical connected VLBI
• Financial models should include
  telecommunications requirements
• Co-ordination of telecommunications activities -
  an agreed view and timing
• Generic network component(s) - building blocks
• Service rap for Astronomy Research e.g. Real-time
  VLBI etc
• Standards Use International VSI-H
• RD Transport protocols - 1GE, 10GE, 10G/40G/160G
  
• Statement(s) Network Of Requirement (SNOR) -
  Locations, Bandwidths, Service
• Communications Solution Design
• Co-ordination Funding activities
• Consortium of suppliers and partners
• Implementation plan
• Instruments
• Construction of New Infrastructures - upgrade
• Design Studies - Technical preparatory -
  evolution to 10GE, 40G, 120G, 160G
• IST Integrated Projects - possible new
  workpackage Advanced Optical Networking proposal

Network Requirements ...

• Scientific instruments integrated at optical
  transport layer
• Network Configuration Star
• Routing Single Path (no path protection)
• Route Protection manual
• Network Management Centre
• Alarm Management
• The data flow is one way - telescope to
  Correlaters
• Data Protocol - VSI-H (others ?)
• Transport jitter free
• Interfaces 1GEathernet and 10G Lambda
  (transparent)
• Evolution - 10GEathernet, 40G, 120G, 160G
• Interface protection (N to 1, manual switch)
• Seamless interconnection with existing research
  Networks
• New build for last mile, middle mile new
  fibre (DWDM)
• Affordability

Questions .

• Will there be an element of Public
  Understanding of Science
• Also, Public Engagement in Science
• Linkage with Educational Initiatives
