Importance of testbed activities

• Different area of science has different
  properties and requirements.
• How (and how much, how fast) data is produced and
  consumed.
• Delay jitter tolerance, buffering behaviors.
• Instrumentation interfaces.
• Many of these properties and requirements usually
  surface only through actual experiments.
• (Even for concerning scientists!)
• Area (even application) specific analysis and
  trouble shooting methods.
• Support mechanisms.

Global collaboration structure ofnetwork
infrastructure and sciences

• Science is essentially International
• Focus on International collaboration of various
  activities.
• Global Infrastructure as catalyst to
  accelerate international Science activities.
• Mutual benefit between Science and
  Infrastructure
• Accumulation of experiences.
• Feedback into global infrastructure control/data
  plane design.
