Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] In the prior art, in the decoding method based on the RS erasure code, the system starts decoding after obtaining the same amount of data as the original data and forming the data to be decoded, and determining the corresponding decoding generation matrix. There are restrictions on the input sequence of data. Generally, the original data needs to be input first, and then the verification data is input. The decoding method is not flexible and the decoding efficiency is low.

[0044] In the decoding method of the present invention, the calculation operation of decoding starts from the first arbitrary fragment obtained, and all decoding work can be completed after obtaining any m-th fragment, and the m fragments can be...

Abstract

The invention provides a decoding method, a decoding device, and a cloud storage method and system, and belongs to the field of cloud storage technology. The decoding method comprises: reading to-be-decoded data from an input buffer zone; transferring the read to-be-decoded data including an original data fragment and a checking data fragment to an output module, and processing the to-be-decoded data in the output module; and selecting the corresponding data fragment according to the number of the data fragments in an original data zone and a to-be-decoded zone of the output module after the processing, performing decoding, and combining the decoded result to whole original data. According to the technical scheme in the invention, parallel processing of decoding and data obtaining can be performed, and the decoding efficiency is greatly improved. The sequence of the to-be-decoded data is not required, and the to-be-decoded including original data and checking data can be processed in the input buffer zone at a random sequence.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a decoding method and device, and a cloud storage method and system. Background technique [0002] Cloud storage refers to a system that integrates a large number of different types of storage devices in the network through application software to work together through functions such as cluster applications, network technology, or distributed file systems, and jointly provide data storage and business access functions. In a cloud storage system, files are generally stored in pieces in multiple cloud storage servers. In addition, during data communication, the data that needs to be communicated will also be divided into multiple fragments and sent to the other party one by one. [0003] In data storage and communication, in order to solve the problem of reliability, Erasure Codes (EC) technology can be used to encode files and divide them into several original data ...
