Abstract:
1. A response time estimator system, the system comprising: a parameter monitor configured to monitor transmission parameters associated with message exchanges between a middleware component and at least one intermittently-available node, the intermittently-available node experiencing connected phases and non-connected phases with the middleware component; an expectation manager configured to determine a current request message at a queue of the middleware component, and configured to determine an expected message exchange time for the current request message and a resulting response message, based on a number of preceding request messages within the queue and on corresponding response messages from the intermittently-available node, and based on at least some of the transmission parameters; and a result predictor configured to perform a comparison of the expected message exchange time and a time-to-live of the current request message, and configured to predict, based on the comparison, whether a receipt of the resulting response message will occur, within one of the connected phases and before expiration of the time-to-live.
