A multi-node exact blood sugar repair code scheme,which can repair multiple system nodes or redundant nodes simultaneously,was shown and proved to against the disadvantages of the existing multi-node repair model in cloud storage.The multi-node exact repair code was combined with a twin-MDS codes framework with health cooperative nodes.In this way,repair bandwidth,the number of repair links and the amount of data to be treated in an intermediate node were reduced,while multi-node were repaired.
Finally,numerical simulation results show that this scheme has greater improvements.In particular,it reduces the load in an intermediate node.And the YEAST INFECTION advantages was more obvious with the more storage nodes in cloud storage.
