Latest Patents

Van Kempen’s listed patent is “Method of Data Replication in a Distributed Data Storage System and Corresponding Device.” The invention defines a replication set of *k* storage devices that holds a particular data item. Each device has a timer whose disconnection timeout is based on that device’s individual downtime distribution.

When a device’s timer expires, the system can add a replacement device to the replication set if the number of connected devices has fallen below a predetermined threshold. The system adjusts timeout values according to the replication set’s criticalness, allowing device replacement to become more or less responsive. Criticalness is determined by comparing the number of connected devices with the predetermined set size.
