Figure 76: Experiments on WAN-in-Lab showing conditions under which FAST, which is normally

very stable, can be made to oscillate. The conditions for this were found using the recently-derived

model. Note that the oscillations are much smaller than those of most TCP variants.

Because of the simple signaling, MaxNet can also be used with a single bit of feedback per

packet, using a scheme called ADPM (adaptive deterministic packet marking), recently

developed at Caltech, the University of Melbourne, and the City University of Hong Kong Error!

Reference source not found.. Unlike most explicit congestion signaling schemes, ADPM is

compatible with standard ECN ("explicit congestion notification") signals.

As well as being applied to MaxNet, ADPM is currently being applied by researchers at the

University of Pittsburgh, in collaboration with Caltech, for an alternative congestion control

approach.
