Abstract

A system and method for connection failover. A plurality of virtual machines connect to a proxy using a protocol library. The proxy establishes a connection to a gateway. A user context including a conversation identifier is stored. The proxy continues a conversation with a second virtual machine based on the conversation identifier and user context if a first virtual machine fails when the conversation is in a ready for failover state.
