Reliable data transmission method and device thereof

The invention provides a reliable data transmission method and a device thereof. The method comprises the following steps: a data transmitting end divides a file to be transmitted into a data packets with serial numbers; according to a preset buffer data packet format, the data packets are packaged into data packets to be transmitted, and then are added to a transmission buffer area: the data packets to be transmitted in the transmission buffer area are transmitted in sequence; the data packets confirmed at a data receiving end in the transmission buffer area are deleted; whether the stoppingtime of the data packets in the transmission buffer area is over a preset time threshold or not is judged, and if so, the data packets are reset to be the data packets to be transmitted; and the transmission process is repeated. In the scheme of the invention, as only the data format and the transmission process at the transmitting end and the receiving of the data packets are controlled, no special data packets are needed to be transmitted between the transmitting end and the receiving end to carry out handshake connection operation, and under the condition that the system expense is less and the data transmission efficiency is high, the problem that the existing UDP (User Datagram Protocol) can not reliably transmit the data can be solved.

Method and apparatus for controlling data transmission volume using explicit rate control and queuing without data rate supervision

Packet flow rate control techniques are enhanced by the interactive and early invocation of packet queuing to control short flows of packets and to eliminate undershoot and overshoot of a targeted flow rate. Packet queuing involves the scheduled release of packets in accordance with flow policies (priorities) to achieve a preselected outgoing target flow rate. The combination of controlled packet queuing and packet flow rate control with appropriate mechanisms for favoring one over the other improves the efficiency of data transmission.
