some more recent work to this point: the EFCM common congestion
controller developed in our group. See

Michael Savoric, Holger Karl, Morten Schlaeger, Tobias Poschwatta, and
Adam Wolisz, "Analysis and performance evaluation of the EFCM common
congestion controller for TCP connections", Computer Networks,
vol. 49, no. 2, pp. 269-294, October 2005, to appear

The complete results are available in the dissertation of Michael
