Abstract: The present disclosure provides a congestion control method and apparatus, and a related device. The method in the present disclosure may include: obtaining a transmission rate of a transmission link, and obtaining a congestion control window size of the transmission link; calculating a congestion risk coefficient of the transmission link based on the transmission rate and the congestion control window size; and determining whether the congestion risk coefficient is not less than a preset threshold, and if the congestion risk coefficient is not less than the preset threshold, triggering an adjustment to the congestion control window size.

Abstract: The present disclosure relates to data distribution methods. One example method includes receiving an access policy, where the access policy includes flow description information, quality information of at least two links, and a data distribution policy on the at least two links, receiving a service data flow, and in response to determining that the access policy includes flow description information of the service data flow, determining link quality information of a link used for transmitting the service data flow, and distributing the service data on the link according to the data distribution policy, where the data distribution policy is a data distribution policy that is determined based on the access policy and that is corresponding to the link quality information and the flow description information of the service data flow.

Abstract: Embodiments of the present disclosure provide a congestion control method, an apparatus, and a system. The method includes receiving, by a first device, an acknowledgement packet that is from a second device and that includes an ECE identifier. Based on an indication of the ECE identifier the first device starts monitoring a plurality of sub streams on a plurality of transmission paths between the first device and the second device, and grouping, into one set, sub streams that meet a congestion control condition. Additionally, intra-set congestion control is performed on the sub streams in the set. Separately congestion control is performed on a sub stream that is not in the set. The congestion control method is applied to a scenario in which data transmission is performed between the first device and the second device by using the MPTCP.
