RESUMING APPLICATION OPERATION OVER A DATA NETWORK

摘要

A system for allowing an application to resume its operation on a new node of a data network after an original application and/or an original node fail to operate over the data network, that comprises: an active node comprising an active application and an active replication software component for replicating changes of the active application; stand-by nodes, where each node comprises a replication of the application and a stand-by replication software component, for replicating changes of the active application that are received from the active replication software component to its corresponding stand-by node; and a high availability software component for instructing each of all nodes to become active or stand-by; for monitoring the availability of the active node and the one or more stand-by nodes and the availability of the active application and the replication(s) of application; and for controlling and communicating with the active and the one or more stand-by nodes.
