DATA CODEC METHOD BASED ON BINARY REED-SOLOMON CODE

摘要

The present invention relates to the field of distributed storage systems, and particularly relates to a data codec method based on binary Reed-Solomon (BRS) code. The method comprises the following steps: (A) using initial data to create a BRS code; (B) updating the BRS code; (C) recreating the BRS code; x-or operations are used in the operations in step (A), step (B), and step (C). The benefits of the present invention are: the method greatly increases data upload and download speeds, thereby significantly reducing system operation complexity (e.g. metadata updating, broadcasting updated data, etc.); the method has high application value and development potential with respect to actual distributed storage systems.
