ABSTRACT:
The present invention provides for congestion and flow control for a data transmission between computers in a network (e.g., a lossless network) by repeatedly setting a transmission rate for the data transmission at predetermined time intervals. Under the present invention, a ratio of a current occupancy to a maximum occupancy of a queue used for the data transmission is provided (e.g., the ratio can be calculated under the present invention, or obtained as input from an external source). The queue can be that of the receiving computer or of any component (e.g., a switch) that resides in the path of the data transmission. In any event, once the ratio is known, the present invention will set the transmission rate for the data transmission based on a comparison of the ratio to at least one threshold.
