A method and device for setting timeout retransmission duration

Abstract

The invention discloses a method and a device for setting an overtime retransmission time length, wherein the method and the device belong to the field of computer technology. The method comprises the steps of transmitting first data to a receiving end on the condition that the overtime retransmission time length is set to a first time length, if confirmation information returned from the receiving end is received in the first time length, determining a time difference between a first data transmitting time point and a confirmation information receiving time point, and obtaining a target transceiving time consumption; according to a correspondence between the prestored data amount and a standard transceiving time consumption, determining the target transceiving time consumption which corresponds with the first data; and if the target transceiving time consumption is shorter than the target standard transceiving time consumption, reducing the overtime retransmission time length from the first time length to a second time length. The method and the device can improve data retransmission efficiency.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for setting the duration of timeout retransmission. Background technique [0002] In the process of data transmission in the wireless network, due to network failure or equipment failure, the data transmission may fail. At this time, the sending end needs to resend the data. [0003] Specifically, the sending end sends data to the receiving end and starts timing. After receiving the corresponding data, the receiving end will return a confirmation message to the sending end. The sending end can set the timeout retransmission time for judging whether the data is sent successfully. If the sending end does not receive the confirmation message returned by the receiving end within the preset timeout retransmission period after sending the data, it can be considered that the data transmission has failed, and the sending end will resend the data to the recei...

Problems solved by technology

[0005] In the case of better network quality, the data transmission speed is faster. If the data can be sent successfully, the time required for the sender to send the data to receive the confirmation message will be very short. However, due to the comprehensive consideration of different network quality , the value of the timeout retransmission time is generally set longer. In this way, when the network quality is better, the sender can confirm that the data transmission failed after waiting for a short time, but it still needs to wait for a long time before confirming the data transmission. Fail, and then resend the data, resulting in low efficiency of data retransmission
