DATA TRANSMISSION METHOD AND APPARATUS

Embodiments of the present disclosure disclose a data transmission method and apparatus, and belong to the field of Internet technologies. The method includes: obtaining interaction information of a transmission link of a current moment; analyzing the interaction information, to obtain link status information corresponding to the interaction information; determining an available bandwidth for current data transmission according to the link status information that corresponds to the interaction information and link status information that corresponds to historical interaction information of the transmission link; and transmitting a data packet to a data receive end according to the available bandwidth. In the embodiments of the present disclosure, data transmission is performed based on the TCP Protocol, neither a data receive end nor a data transmit end needs to support an additional protocol, and applicability is relatively strong.
