Abstract: A method of network data transmission is implemented by a computer device, and includes: defining every data packet to be generated by a specific application program as belonging to a direct data packet; defining every data packet to be generated by other application programs as belonging to a controlled data packet; determining which one of the direct data packet and the controlled data packet a data packet belongs to; and when it is determined that the data packet belongs to the direct data packet, transmitting the data packet, and delaying transmission of another data packet which is determined as belonging to the controlled data packet and which is received later than the data packet that is determined as belonging to the direct data packet.
