 (and enter Packeteer as an Assignee Name)

The relevant patent seems to be #6,205,120: Method for
transparently determining and setting an optimal minimum
required TCP window size.

I don't understand how calculating the bandwidth delay
product and sticking it in a packet header counts as
patent-able, but I hear that sort of surprise is common.  I
certainly don't understand how it applies to UDP as
described in the patent claim.

Do you know of other boxes that do the same thing? perhaps
some that were built before 1998? ;)

(I wrote an infocom 2000 paper on a similar scheme using the
advertised window to throttle long downloads over a modem when
competing with interactive traffic)
