Message Replication and Consumer Database Synchronization Algorithms and System for Highly Available High Performance Intelligent Networks

For maximizing consumer satisfaction, intelligent network services such as the prepaid card service need to be built upon mechanisms that provide efficiency along with high availability. With multiple replicated service control point (SCP) databases in each one of a number of LAN sites interconnected by WANs for ease of information access and catastrophe tolerance, the proposed distributed software system employs a highly efficacious and innovative fault-tolerant algorithm for replication of messages originating at an SCP to all the others, and a novel asynchronous algorithm to achieve continual synchronization of all the databases with the help of the replicated messages received at different destinations.
