Abstract
A method for allocating a fair bit rate for an ABR service. Forward and backward RM cells traversing a link 1 are received at an ATM switch. Both the forward and backward RM cells are associated with a session, with the forward RM cells being transmitted from a source to a destination and the backward RM cells being transmitted from the destination to the source. An advertised rate .gamma..sub.l for link 1 is updated when a backward RM cell associated the session is received based on a change in a bottleneck bandwidth .DELTA..lambda. of the session and a change in a bottleneck status .DELTA..beta. of the session. The explicit rate .lambda..sup.ER contained in the backward RM cell is rewritten as a minimum of the advertised rate .gamma..sub.l and the explicit rate .lambda..sup.ER. The backward RM cell is then transmitted to the source of the RM cell.
