Welcome

• Informal, local event today
• Formal, global event is annual open house in
  August every year starting 2010
• Current Status
• Research projects
• Staff hiring
• Equipment purchase
• Publicity
• Outreach

Theory and Practice

• There is nothing more practical than a good
  theory
• Theory as the brain and systems as the heart
• Rigor or relevance either but not both?
• Relevant question or elegant answer?
• Why theory is inalienable
• Explanatory (rather than descriptive) models
• Top-down design with predictive power
• Why theory is incomplete
• Sensitivity to math crystallization
• Need to make a difference in live networks

Not Just Yet Another Testbed

• 1. Focus on edge networking (rather than backbone
  and sensor networks)
• 2. Theory-inspired implementation
• Validate predictions
• Falsify assumptions
• Tighten characterizations
• Inspire new questions
• Technology transfers
• Innovation incubation
• Student education
