Method and system for database synchronization
First Claim
1. A method for data synchronization, characterized in that at least one data element is delivered between at least one master and replica database through at least one content router node, where next recipient of the data element is selected in the content router node based on destination address of the data element and routing information of the current content router node or any of the route'"'"'s previous content router nodes or the originating database.

Abstract
The invention relates to a method, arrangement and content router node for database synchronization. Especially the invention relates to synchronization messaging using a content routing mechanism. In particular the invention relates to content routing where data elements are delivered between master and replica databases through a number of content router nodes. The content router node receives the data elements and decides next recipient of the data elements based on the data element and routing information of the current content router node or any of the route'"'"'s previous content router nodes or the originating database. The content router node may also be arranged to wait a specified wait time for other data elements whose next destination address is the same node as that of the received data elements and if the addresses are same, the content router node aggregates the received data elements into one message.
