Abstract
Preserving session state correlation in a distributed computing environment in which a service module instance receives messages from a general input buffer. The general input buffer is not accessed by a service module instance once the service module instance is determined to be recycled. After the service module instance receives a session initiation message through the general input buffer, a session-oriented input buffer is associated with the service module instance. Any subsequent session messages are then received by the service module via the session-oriented input buffer. Even if the service module instance was determined to be recycled mid-session, the service module instance would still operate to process all of the remaining session messages from the session input buffer, thereby preserving session continuity.
