Data transmission control method and related device

The invention discloses a data transmission control method. The method comprises the following steps: a first device sends a data packet to a second device; wherein handshake connection exists between the first device and the second device; forming a packet loss list according to the packet loss information fed back by the second equipment; judging whether the number of data packets in the packet loss list and the sending rate are adjusted or not; and if yes, data packet retransmission is carried out on the second device based on the adjusted packet loss list and the adjusted sending rate. On the basis of the handshake link between the first device and the second device, the reliability of data transmission is firstly kept, and then non-fixed data packet retransmission is carried out by adopting the packet loss list after the data packet quantity adjustment and the sending rate after the rate adjustment, so that congestion crashing caused by data packet retransmission is avoided, and the data transmission eff
