Abstract
A method for a non-disruptive TCP connection switch is introduced that allows the re-establishment of communications between a remote host and a new host when the host originally in processing communication with the remote host takes an outage. The present invention particularly relates to loosely coupled environments connecting to a TCP/IP network. The method involves three important steps of initialization, during which all hosts and remote hosts are identified by a communication box; failure detection step during which a host outage is detected by the communication box; and re-registration step during which the communication box provides and re-establishes processing connection between the remote host and a new host replacing the initial failing host.
