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.

Abstract: Example embodiments provide for a binding mechanism between RM protocols and request-response transport protocols (e.g., HTTP) in a one-way message exchange pattern. The present invention leverages existing network characteristics of request-response transport protocols without reconfiguration or deployment of new infrastructure services. A request-response transport model is asymmetrical in nature and provides two data-flows; a request flow and a reply flow. When an initiator is not addressable and/or when communication requires a request-response transport, the present invention allows infrastructure and application messages to be sent on the request flow, while acknowledgments and other infrastructure messages may be sent back across the reply flow of the transport.
