AT&T Intellectual Property Assigned PatentDistributed storage of data
By Francis Pelletier on 2017.03.17
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Multi-reliability regenerating, (MRR) erasure codes are disclosed. The erasure codes can be used to encode and regenerate data. In particular, the regenerating erasure codes can be used to encode data included in at least one of two or more data messages to satisfy respective reliability requirements for the data. Encoded portions of data from one data message can be mixed with encoded or unencoded portions of data from a second data message and stored at a distributed storage system. This approach can be used to improve efficiency and performance of data storage and recovery in the event of failures of one or more nodes of a distributed storage system."
