一种基于二进制域里德所罗门码的数据编解码方法
摘要：
本发明涉及分布式存储系统领域，尤其涉及一种基于二进制域里德所罗门码(Binary Reed-Solomon Code,简为BRS码)的数据编解码方法，包括以下步骤：(A)原始数据构建二进制域里德所罗门码；(B)更新二进制域里德所罗门码；(C)重构二进制域里德所罗门码；所述步骤(A)、步骤(B)以及步骤(C)中的运算均采用异或运算。本发明的有益效果是：通过该方法大大提高了数据上传和下载的速率，很大程度上减少了系统操作复杂度(如元数据更新、更新后的数据广播等)；在实际的分布式存储系统中具有很高的应用价值和发展潜力。
摘要（英）：

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.
