TCP Switch: when does circuit switching make sense?

Pablo Molinero-Fernández,
Department of Electrical Engineering,
Stanford University

About the talk:

This talk will revisit most of the reasoning that led to the adoption of packet switching in the Internet. I will analyze these common conceptions, and I will try to distinguish reality in the Internet from the myths. I will compare the characteristics of packet switching to those of circuit switching, by comparing a router with a circuit switch, and I will then point out when it can make sense to use circuits, rather than plain packets.

The talk will end with a description of my current research; a TCP switch, an architecture that uses circuit switching with a granularity as thin as a TCP flow, that takes advantage of the speed and large capacity of TDM and optical switches. Finally a nice side effect of this architecture is its ability to provide hard QoS guarantees.

About the speaker:

Pablo Molinero-Fernández is a Ph.D. student at Stanford University, working with Prof. Nick McKeown in the High Performance Networking Group. He holds M.S. degrees in Electrical Engineering, Telecommunications Engineering and Physics from Stanford University, Technical University of Madrid-UPM (Spain) and ENST-Paris (France), and UNED (Spain) respectively.
