Abstract
A system, method and computer program product for implementing network connection failover during application service interruption. While the application is quiesced, a network socket that terminates a network connection to a network peer is maintained on behalf of the application. The socket's network connection state information is sustained by providing acknowledgements of incoming network traffic to the network peer that prevent the peer from terminating the connection. Upon restart, the application is brought up with a blocked socket. The state of the blocked socket is conformed to a current network connection state of the original socket and the blocked socket is unblocked.
