<p>Disclosed in the present invention are a method, a device and a system for uplink flow control, wherein setting a flow control mark in a downlink physical frame when detecting that the uplink data caching amount of a next-level slave equipment is greater than a preset congestion threshold value; transmitting the downlink physical frame carrying with the flow control mark to each next-level slave equipment, so that the next-level slave equipment is facilitated to carry out a flow control of uplink transmission of data per se when detecting the downlink physical frame carrying with the flow control mark. According to the method, device and system provided by the invention, communication bandwidth is reasonably allocated to all slave equipments on a link; and the bandwidth utilization ratio of communication links is increased.</p> |
