Abstract

A flow control method and system, and a device are provided to implement flow control in a process of transmitting a media stream between devices. The method includes: receiving, by a first device, a media stream that is sent by a second device at a first rate; instructing based on a rate of a media stream in a first time period in which a buffer usage rises from a first threshold to a second threshold, the second device to send a media stream to the first device at a second rate which is less than the first rate; instructing based on a rate of a media stream in a second time period in which the buffer usage rises from the second threshold to a third threshold, the second device to send a media stream to the first device at a third rate which is not greater than the second rate.
