Problems solved by technology

[0005] The technical problem solved by the present invention is to solve the waste of bandwidth under the action of the window mechanism. When the data in the sending window is full or less, the unconfirmed data is actively selectively sent, and a data transmission method based on the window mechanism is provided. Transmission method to improve the transmission efficiency of the sending end during data transmission, and improve the receiving accuracy rate of the receiving end through retransmission, thus effectively reducing the transmission delay

Embodiment Construction

[0029] see figure 2 , is a schematic diagram of improving bandwidth utilization under the action of the window mechanism in the present invention. In order to solve the waste of bandwidth caused by the window mechanism, the present invention selects and sends unconfirmed data by judging whether the data in the sending window is full or the data is less during the data transmission process from the sending end to the receiving end, wherein, The unconfirmed data includes new data and data to be retransmitted. That is, by comparing the size of the sending window with the size of the pre-configured sending window occupancy threshold, it is determined whether to send as much unconfirmed data in the sending window as possible to improve the receiving accuracy of the receiving end, thereby obtaining a smaller transmission delay .

Abstract

The method includes (1) setting up threshold value of engaged sending window, and monitoring size of the sending window and data to be sent in real time; (2) determining whether size of the sending window is less than threshold value of engaged sending window; if no, selecting unconfirmed data from size of the sending window to send, ending; if yes, then executing step (3); (3) determining whether size of the sending window is smaller than size of data to be sent; if no, selecting unconfirmed data from data to be sent to carrying out sending; if, yes, returning back to (1). The invention solves waste of bandwidth under operation of window mechanism. When data is full in the sending window or data are less, the method carries out sending selectively forwardly in order to raise sending efficiency at sending end in data transmission procedure. Moreover, using retransmission increases correction rate of reception at receiving end so as to lower time delay from end to end effectively.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a method for data transmission based on a window mechanism. Background technique [0002] In the process of data transmission, it is often encountered that the transmitted data is wrong or the transmitted data is not received, which will affect the normal operation of the entire system. In order to ensure the normal operation of the system, some systems that support the retransmission mechanism adopt Keep retransmitting the same data until receiving confirmation from the peer that the data is received correctly. Usually, in data transmission, there are the following mechanisms: window mechanism, confirmation mechanism and retransmission mechanism. Wherein, the realization principle of the window mechanism, that is, the sliding window mechanism, is to keep the window sizes of the receiving end and the sending end consistent. For example, if the configuration of the sending window ...
