Advanced Network Sciences talk, UC San Diego
Brownian models provide tractable high-level descriptions of networks in a variety of application areas. This talk will review work in two areas: the modelling of multi-path routing in the Internet, and the design of ramp metering policies for highway networks.
In both areas Brownian models are able to exploit the simplifications that arise in heavy traffic, and to make clear the main performance consequences of resource allocation policies.
