Credit based flow control schemes are another alternative, where downstream queues signal back to upstream queues special "credits" which are used by the upstream queues in order to decide if and how much traffic can be forwarded downstream [6], [7].…”

Abstract-This paper proposes and analyzes the efficiency of novel backpressure schemes for Terabit switch fabrics. The proposed schemes aim at buffer optimization under uniform traffic distribution with Bernoulli packet arrival process. Results show that a reduction of the needed maximum buffer capacity with up to 47% can be achieved with switch-internal backpressure mechanisms at the expense of a small control overhead.

“…On the other hand, in the integrated services network, it is important to be able to handle a variety of traffic types having different delay requirements and loss probabilities in the same network [3,4]. Voice traffic needs small delay requirements rather than high reliability, while data traffic needs high reliability rather than small delay requirements.…”
