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

Theory-Practice Synergy
Theory
Bigger
Overlap
Practice
New Questions
Do them both
5
An Edge Between Theory and Practice

From Dichotomy to Union:
Practice

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
