Abstract

Congestion control is important for multimedia transportation in ATM networks. Congestion situation can be indicated by a single-bit congestion information, called congestion bit, carried in each cell header. Some congestion bit setting schemes have been sued for congestion control in these years. Although the existing schemes work well, they can not provide accurate congestion information, which is needed for some congestion control algorithms. In this paper,we propose a new scheme to set the single-bit congestion information by using statistics approach so that it can convey more accurate information. The existing statistics approach schemes can not provide correct congestion information while congestion occurs at more than one switch simultaneously. On the contrary, the new scheme can provide the correct information of the congestion situation at the bottle-neck, where the congestion is heaviest on the way from the traffic source to its destination. Theoretical analyses and simulation results show that the new approach is efficient.
