FLOW CONTROL METHOD AND DEVICE

Disclosed are a flow control method and device, for solving the problem existing in the prior art that a process of relieving congestion of nodes is relatively slow. In the present disclosure, a target node sends, to a second node, flow control information of the target node and/or flow control information of at least one first node; the second node adjusts, according to the received flow control information, the volume of data sent to the target node; if the first node is a child node and/or a lower layer node of the child node, the second node is a parent node and/or an upper layer node of the parent node; and if the first node is a parent node and/or an upper layer node of the parent node, the second node is a child node and/or a lower layer node of the child node. According to flow control information of at least one of the parent node of the target node, the upper layer node of the parent node, the child node and the lower layer node of the child node, the second node can adjust the volume of data sent to the target node, and thus the congestion situation of nodes can be quickly relieved, increasing the data transmission efficiency.
