Theory and Practice ¾ “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? ” … ¾ Why theory is inalienable: ¾ ¾ q q ¾ Explanatory (rather than descriptive) models Top-down design with predictive power Why theory is incomplete: q q Sensitivity to math crystallization Need to make a difference in live networks 3
Theory-Practice Divide Industry Tear Down This Wall ! Modeling Reality Model Transfer Theory Mathematics 4
Theory-Practice Synergy Theory Bigger Overlap Practice New Questions Do them both 5
An Edge Between Theory and Practice ¾ From Dichotomy to Union: Practice Theory Practice The Princeton EDGE Lab 6
Not Just Yet Another Testbed 1. Focus on edge networking (rather than backbone and sensor networks) 2. Theory-inspired implementation: ¾ ¾ Validate predictions Falsify assumptions Tighten characterizations Inspire new questions Technology transfers Innovation incubation Student education 7
