Abstract
A system for maintaining a non-disruptive connection between a local host and a remote host is introduced that allows the re-establishment of processing communications between the remote host and a new host in case the first host originally in processing communication with the remote host experiences an outage. The present invention particularly relates to loosely coupled environments connecting to a TCP/IP network. The system uses a communication box or an offload frontend box for holding all socket associations between the remote host and the local hosts. Each socket connection associates the remote host to an application being run on the local host but maintained by the communication or the offload frontend box. The offload frontend box detects a host outage through its channel connectivity and holds all processing and communication data related to the failing host until a new connection is established between a second host and the remote host, at which time the box transfers all such data to the second replacing host.
