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
