CS Colloq: Internet Equilibrium Analysis Through Separation of User and Network Behavior

Title: Internet Equilibrium Analysis Through Separation of User and Network
BehaviorSpeaker: Prof. Y.C. Tay (National University of Singapore)ABSTRACT:
Internet complexity makes reasoning about traffic equilibrium difficult, partly
because users react to congestion. This difficulty calls for an analytic
technique that is simple, yet have enough details to capture user behavior and
flexibly address a broad range of
issues.This talk presents such a technique. It treats traffic equilibrium as a balance
between an inflow controlled by user demand, and an outflow provided by network
supply (link capacity, congestion avoidance, etc.). This decomposition is
demonstrated with a surfing session model, and validated with a traffic trace
and NS2 simulations.The technique's accessibility and breadth are illustrated through an analysis
of several issues concerning the location, stability, robustness and dynamics
of traffic equilibrium.(Joint work with D. Nguyen Tran, Eric Y. Liu, Wei Tsang Ooi and Robert Morris)BIO:
