Apologies for the late notice.

Title: Network Congestion Control with Markovian Multipath Routing

Speaker: Roberto Cominetti, Departamento de Ingeniería Industrial, Universidad de Chile

Date: Tuesday 8 February 2011 Time: 4.00pm AEST Place: V206 - Via access grid

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.

All welcome to attend
