Abstract
A system receives a flow of data packets via the link and determines a target bandwidth to be allocated to the flow on the link. In response to the flow, the receiving system transmits data to the sending system. The transmitted data control the sending system such that when the sending system transmits subsequent data packets to the receiving system, such subsequent data packets are transmitted at a rate approximating the target bandwidth allocated to the flow. In one embodiment, the rate at which the transmitted data from the receiving system arrive at the sending system determines the rate at which the sending system transmits the subsequent data packets. The receiving system can control the rate by delaying its response to the sending system according to a calculated delay factor. In another embodiment, the data transmitted from the receiving system to the sending system indicate a maximum amount of data that the receiving system will accept from the sending system in a subsequent data transmission. The maximum amount is determined so that when the sending system transmits subsequent data packets according to that amount, data is transmitted by the sending system to the receiving system at a rate approximating the target bandwidth.
