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.
