Problems solved by technology

[0003] The existing processing method is to delete the wrong data when the data is wrong, and re-request the data source to send the data, but for many data sinks, such as the data sink in the neural network, once the data is delivered, it may affect the data sink. The data set in is polluted, even if the wrong data is deleted, it will have an irreversible impact on the data sink, resulting in final data deviation

Embodiment approach

[0053] As an implementation manner, extracting the first characteristic information of the source data includes:

[0054] Get the file size of the source data;

[0055] Calculate the distance of the preset data clusters in the source data.

[0056] By presetting the data cluster, the data cluster can be any combination of continuous data that appears more than once in the source data. When the number of occurrences is large, the average or histogram distribution of each distance can also be calculated.

[0057] As an implementation manner, extracting the second characteristic information of the delivery data includes:

[0058] Get the file size of the delivered data;

[0059] Calculate the distance of the preset data cluster in the delivered data.

[0060] By extracting the above-mentioned first feature information and second feature information, it is possible to quickly and accurately determine whether there is a difference between the source data and the delivery data, t...

Abstract

The invention discloses a data transmission error processing method and system. The method comprises creating a volume shadow copy for a data set of a data sink, adding a timestamp when the source data is sent, recording all changes of the data set in the target data sink after timestamping as data changes, extracting first feature information of source data and second feature information of delivery data, comparing the first feature information with the second feature information, when the second feature information does not accord with the first feature information, restoring the data set toa timestamp node according to the data change, and restoring the data set of the data sink by using the volume shadow copy when the data transmission has an error, so that the problem that the data sink is polluted due to the error of the data transmission or the irreversible problem caused by the input of error data is effectively avoided, and the integrity and correctness of the data sink are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission error handling method and system. Background technique [0002] Data transmission is the communication process in which data is transmitted from the data source to the data sink. According to the order of data transmission, it can be divided into parallel transmission and serial transmission. According to the synchronization method, it can be divided into synchronous transmission and asynchronous transmission. In the process of data transmission, it may Errors in data transmission may occur due to external interference, signal distortion and signal distortion; [0003] The existing processing method is to delete the wrong data when the data is wrong, and re-request the data source to send the data, but for many data sinks, such as the data sink in the neural network, once the data is delivered, it may affect the data sink. The data set in is...
