The present application discloses a congestion control method, an electronic device and a readable storage medium. Each time the sending end device receives an ACK packet, it determines a new sending rate, and determines the amount of data to be sent in a new round of sending according to the sending rate and the time interval between two adjacent rounds of sending. Afterwards, when the current time reaches the second moment, the data packets are sent at a uniform speed according to the sending rate and the amount of data, so that the sending of these data packets can be sent smoothly.
