Method for preserving correlation between messages of the same session

摘要

Preserving session state correlation in a distributed computing environment in which a service module instance (211A) receives messages from a general input buffer (212A). The general input buffer (212A) is not accessed by a service module instance (211A) one the service module instance (211A) is determined to be recycled. After the service module instance (211A) receives a session initiation message (231) through the general input buffer (212A), a session-oriented input buffer (212B) is associated with the service module instance (211A). Any subsequent session messages are then received by the service module instance (211A) via the session-oriented input buffer (212B). Even if the service module instance (211A) was determined to be recycled mid-session, the service module instance (211A) would still operate to process all of the remaining session messages from the session-oriented input buffer (212B), thereby preserving session continuity.
