Title: Network Congestion Control with Markovian Multipath Routing
Speaker: Roberto Cominetti, Departamento de Ingenierķa Industrial, Universidad de Chile

Abstract We describe an integrated model for TCP/IP protocols with multipath routing.
The model combines a Network Utility Maximization for rate control, with a Markovian
Traffic Equilibrium for routing. This yields a cross-layer design in which sources
minimize the expected cost of sending flows, while routers distribute the incoming flow
among the outgoing links according to a discrete choice model. We prove the existence
of a unique equilibrium state, which is characterized as the solution of an
unconstrained strictly convex program of low dimension. A distributed algorithm for
solving this optimization problem is proposed, with a brief discussion of how it can be
implemented by adapting current Internet protocols.
