Flow control is one of the
exciting challenges in telecommunication networks. From a control theoretic
view point these are extremely complex and difficult problems, since they often
require decentralized mechanisms, information is often partial and noizy. Moreover,
in high-speed networks the propagation delay may be quite large in comparison
to the transmission delay, so that the information available to the controller
are typically delayed and out of date. I have been involved in the analysis of
the TCP/IP window-type congestion control within a contract with France Telecom
- C.N.E.T. I have also been interested in rate-based flow control, which has
been selected by the ATM forum as the main approach for the flow control in in
the Available Bit Rate (ABR) service. I have especially been interested in applying
control theoretical tools in such control schemes.
