ABSTRACT:
Techniques allow a client to be migrated from a session that has been established for a client on a server to another session on another server in a way that is a transparent to the application for which the initial session was established. The sessions are migrated under conditions in which a copy of session state of the session to migrate from the source node does not have to be captured and restored to a destination session.
