    摘要: The backpressure flow control mechanism is widely used in telecommunications network. Actions of the flow control scheme are not instantaneous in that latency always exists between action and reaction, resulting in a flow control round trip time. This flow control round trip time causes ambiguity in determining the amount of traffic in transit. The invention monitors the amount of traffic which is on the way toward the queue during the past period of the round trip time, thus eliminating the ambiguity. A more precise control of traffic flow is possible, realizing reduction of storage space in the queue by one half. In one embodiment, the invention keeps a historical record of flow control signals sent back during the most recent flow control round trip time.
