Abstract
A network routing table includes destination addresses of destination applications hosted on peer nodes of a network. A primary processor registers a first destination application and a second destination application, where the first destination application is the same as the second destination application and both the first destination application and the second destination application have the same destination address. That processor also provides the peer nodes and a secondary processor with a copy of the table. When the first destination application is inactivated, all peer nodes and the secondary processor are provided with a copy of an updated routing table indicating inactivation of the first destination application and routing of the application message to the second destination application. A further application message addressed from any of the peer nodes to the destination address associated with the inactivated first destination application will be routed, via the updated routing table, to the second destination application having the same destination address as the inactivated first destination application. The secondary processor provides the copy of the routing table and the copy of the updated routing table in case of failure of the primary processor in response to a request from the querying peer node.
