Data transmission system with self-adaptive network bandwidth

The invention discloses a data transmission system with a self-adaptive network bandwidth. According to the invention, the available network bandwidth of the network link between the sending end device and the receiving end device is detected at regular time, and the data packet to be transmitted is transmitted in blocks according to the detected available network bandwidth and the predefined data transmission strategy; the data blocks are small and the transmission time is short, so the load pressure of the network link can be reduced, and the occupation time of the network link is reduced, so that the data is transmitted by self-adapting to the network bandwidth of each time period, and the data transmission efficiency of the network link is improved. 本发明公开了一种自适应网络带宽的数据传输系统。本发明通过定时探测发送端设备与接收端设备之间的网络链路的可用网络带宽，根据探测的可用网络带宽，按照预先定义的数据传输策略，将待传输数据包分块传输，由于数据块较小，传输时间较短，能够降低网络链路的负载压力，减少网络链路的占用时间，从而实现自适应各个时段的网络带宽传输数据，提高网络链路数据传输效率。
