Title: Method, system and computer program for replicating data in a distributed computed environment

Abstract: A method for replicating data in a distributed computer environment wherein a plurality of servers are configured about one or more central hubs in a hub and spoke arrangement. In each of a plurality of originating nodes, updates and associated origination sequence numbers are sent to the central hub. The hub sends updates and associated distribution sequence numbers to the plurality of originating nodes. The hub tracks acknowledgments sent by nodes for a destination sequence number acknowledged by all nodes. Thereafter, a highest origination sequence number is sent from the central hub back to each originating node.
