DEC has a nice technical report about the flow control mechanism used in
the GigaSwitch.  Your DEC salesperson should be able to get you a copy,
and probably some other interesting stuff, (make your salesperson earn
his or her living...).

In some sense, you may be asking the wrong question.  I think the 
GigaSwitch flow control mechanism pushes the buffering requirements back
to the FDDI stations (i.e., routers).  Consult the DEC report for the
real answer.

If necessary, I can dig up the document number.
