Description

Background In the process of data transmission, congestion control is an important link for ensuring efficient and stable operation of a network. Congestion control refers to estimating network bandwidth according to transmission information (such as packet loss rate, time delay, etc.) of transmitted data, and dynamically adjusting transmission modes such as transmission rate of subsequent data based on the estimated bandwidth so as to reduce network congestion. Conventional congestion control mostly adjusts transmission strategies by the transmission status of individual data packets. However, since data is transmitted, a complete data unit (e.g., a video frame) is often encoded and divided into a plurality of smaller data packets for transmission, so as to improve transmission efficiency. The congestion control method according to the transmission state of each data packet in the related art may not accurately reflect the overall transmission condition of one complete data unit, and the transmission strategy is adjusted according to the transmission state of each data packet, so that erroneous judgment may be generated on the transmission state of each data unit, thereby affecting the congestion control effect, and the real-time performance and stability of data transmission are difficult to be effectively ensured by the determined transmission strategy.
