         Myths About Congestion Management in High-Speed Networks
                                by Raj Jain
 
Weaknesses in several recently proposed ideas about congestion control  and
avoidance  in high-speed networks are identified.  Both sides of the debate
concerning prior-reservation of resources versus walk-in service, open-loop
control  versus  feedback  control, rate control versus window control, and
router-based  control  versus  source-based  control  are  presented.   The
circumstances  under  which  backpressure  is  useful  or  not  useful  are
discussed, and it  is  argued  that  a  single  congestion  scheme  is  not
sufficient,  but  that  a  combination  of  several schemes is required for
complete congestion management in a network.
