Abstract: METHODS, APPARATUS AND PROGRAM PRODUCTS FOR CONTROLLING A FLOW OF A PLURALITY OF PACKETS IN A COMPUTER NETWORK ARE DISCLOSED. THE COMPUTER NETWORK INCLUDES A DEVICE DEFINING A QUEUE(20,24,28,34). THE METHODS APPARATUS AND PROGRAM PRODUCTS INCLUDE DETERMINING A QUEUE LEVEL FOR THE QUEUE AND DETERMINING AN OFFERED RATE OF THE PLURALITY OF THE PLURALITY OF PACKETS TO THE QUEUE(92). THEY ALSO INCLUDE CONTROLLING A TRANSMISSION FRACTION OF THE PLURALITY OF PACKETS TO OR FROM THE QUEUE, BASED ON THE QUEUE LEVEL, THE OFFERED RATE AND A PREVIOUS VALUE OF THE TRANSMISSION FRACTION SO THAT THE TRANSMISSION FRACTION AND THE QUEUE LEVEL ARE CRITICALLY DAMPED IF THE QUEUE LEVEL IS BETWEEN AT LEAST A FIRST QUEUE LEVEL AND A SECOND QUEUE LEVEL(94). SEVERAL EMBODIMENTS ARE DISCLOSED IN WHICH VARIOUS TECHNIQUES ARE USED TO DETERMINE THE MANNER OF THE CONTROL.FIG.12
