Abstract

A data source includes a number of different messages to exchange with an occasionally connected device. When the device connects with the data source, the exchange of messages occurs transparently according to a set priority and order. Each message has associated therewith a set of one or more stamps that are evaluated and acted on based on a rule set associated with the device. Furthermore, the bandwidth (or cost) of the communication link connecting the machines is used in conjunction with the stamps and rules. In this manner, the device can receive information in a manner that is dependent on its associated rule set and also the speed, reliability, cost and other characteristics of the communications link.
