Embodiment Construction
[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0050]The main idea of the present invention is that when the sender resends the sent data after waiting for the response frame to time out, it starts sending from the next frame of the data frame corresponding to the received response frame. Therefore, it is not necessary to retransmit the data already received by the receiver, reducing invalid retransmission and improving transmission efficiency.
[0051] In the present invention, when receiving the response frame corresponding to the data frame before the last data frame sent by the current window, the data is not retransmitted immediately, but continues to wait for the other party's data response frame, thereby reducing the response frame. Dependence, reduce the data retransmission caused by the receiver res...
