A NEW SINGLE-BIT FEEDBACK CONGESTION SCHEME FOR ATM NETWORKS

The design of efficient congestion control mechanisms is critical to t he successful use of ATM networks for the transport of multimedia traf fic. Several mechanisms, based on feedback control, have been recently proposed in the literature, where the feedback information is a singl e-bit carried in the cell header for source rate adaptation. This pape r proposes a new single-bit feedback scheme that can convey congestion information, e.g. queue(s) size and link(s) utilisation at the switch es, more accurately than existing similar ones, and without extra impl ementation cost. Results from both theoretical analysis and simulation are presented to demonstrate its higher degree of accuracy. (C) 1998 Elsevier Science B.V.
