Paul J. Holenstein, Gary E. Strickler, Eugene P. Jarema, and Dr. Bruce Holenstein secured for Gravic US Patent No. 7,523,110 entitled High Availability Designated Winner Data Replication on April 21, 2009.
Abstract
Collisions are resolved in a database replication system. The system includes a plurality of nodes arranged in either a master-slave or network configuration. Each node includes a database, wherein changes made at the databases of each node are replicated to the databases at one or more of the other nodes. When a collision is detected during data replication between multiple nodes, the collision is resolved by a rule that gives precedence to certain nodes over other nodes.
Although useful for a variety of applications, this technology is particularly well-suited to the telco space. Please contact us for more information.
