Abstract
The present invention monitors the receipt of messages between two endpoints on established sequence session in accordance with a Reliable Messaging protocol for Web Services (RM-WS protocol). The messages received may be application or infrastructure messages (e.g., acknowledgement messages in accordance with the RM-WS protocol). Further, the present invention defines a time period known as the inactivity timeout, which is an upper limit to the time that may pass without receiving a message (either application or infrastructure) on the sequence session. Based on this inactivity timeout period, the present invention calculates time periods for sending idempotent infrastructure messages in accordance with the RM-WS protocol for verifying and maintaining connection liveliness.
