Congestion control for FAST networks: theory and experiments

It is becoming well accepted that current congestion control mechanisms of the Internet do not scale properly to high-speed, long distance networks, and a variety of modifications to TCP and AQM are being proposed to address this challenge. This necessary overhaul gives, in our view, an opportunity to seek a more solid analytical backing to designs which up to now have been mostly ad-hoc. In particular, using fluid-flow models of traffic and feedback control theory, we have developed a family of control laws with provably attractive equilibrium and stability features, scalable to arbitrary network topologies and parameters. These laws can be approximated by packet-level protocols that imply a modest modifications to current TCP and AQM schemes. In this talk, we present an overview of the theory and of some of the experimental efforts to deploy such FAST protocols.

Biographical Sketch:
Fernando Paganini (M'90) received his Ingeniero Electricista and Licenciado en Matematica degrees from the Universidad de la Republica, Montevideo, Uruguay, in 1990, and his M.S. and PhD degrees in Electrical Engineering from the California Institute of Technology, Pasadena, in 1992 and 1996 respectively. From 1996 to 1997 he was a postdoctoral associate at MIT. Since 1997 he has been with the Electrical Engineering Department at UCLA, where he is currently Associate Professor. His research interests are robust control, distributed control, and networks. Dr. Paganini is the recipient of the O. Hugo Schuck award for best paper in the 1994 American Control Conference, the Wilts and Clauser Prizes for his PhD Thesis at Caltech in 1996, the 1999 NSF CAREER Award and the 1999 Packard Fellowship.
