Embodiment Construction

[0031] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] refer to figure 1 A method for incremental data transmission according to an embodiment of the present invention is proposed. The data incremental transfer method includes:

[0033] Step S10, during data transmission, comparing the time stamp of the data at the receiving end with the time stamp of the data at the transmitting end;

[0034] Step S11, when the time stamp of the data at the receiving end is smaller than the time stamp of the data at the transmitting end, start the data transmission.

[0035] Taking the data transmission between the server (transmitting end) and the client (receiving end) as an example, the above incremental data transmission method will be described in detail below.

[0036] Assuming that the data from the server is transmitted to the client, first a timestamp file can be creat...

Abstract

The invention discloses a data increment transmission method and device. The method comprises the following steps: when data is transmitted, comparing a timestamp of receiving end data with a timestamp of transmitting end data; and when the timestamp of the receiving end data is smaller than the timestamp of the transmitting end data, starting the data transmission. According to the data increment transmission method and device, the previous data transmission timestamp is recorded on a receiving end; when the data is transmitted again, only revised or newly-added data after the maximum timestamp in a server needs to be detected for transmitting, so that the transmitting data amount is greatly reduced, the transmitted data does not need to be detected, and the data transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a method and device for incremental data transmission. Background technique [0002] In the prior art, data transmission generally adopts a non-incremental transmission mode, such as an append mode and an overwrite mode. Both of the above two modes need to detect all the transmitted data; after the detection is completed, the append mode will no longer transmit the data that already exists in the receiver (judged according to the same code); while the overwrite mode will transfer the existing data Change it. [0003] The aforementioned non-incremental transmission method for data transmission requires detection and even transmission of all transmitted data, which is time-consuming. Contents of the invention [0004] The main purpose of the present invention is to provide a method and device for incremental data transmission, which improves the efficiency of data trans...
