Here Data Technology Assigned Patent

Here Data Technology, Shenzhen, China, has been assigned a patent (11461203) developed by Hao, Bin, Zhu, Jian, Zhang, Jingyao, Guangdong, China, for “systems and methods of handling node failure in a distributed data storage using multi-layer consistent hashing.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed is a systems and methods of distributed data storage using multi-layers consistent hashing comprising: a plurality of storage nodes providing data storage and redundancy protection, a plurality of management nodes maintaining the properties of the storage nodes and mapping information from virtual groups to storage nodes, a plurality of monitor nodes maintaining the of storage nodes and handling the changes of s of storage nodes including joining, decommissioning and failure, and one or more clients providing entries for applications or users to access the storage system. The storage nodes is in a hierarchical tree arrangement, and each storage node in each layer of the tree is allocated with a plurality of identities and configured for remaining hash space with consistency. Instead of sharing one hash space among all storage nodes, there are a plurality of hash spaces kept consistent in each layer of the storage hierarchical tree.”

The patent application was filed on 2018-07-10 (17/059468).
