Abstract
A method (200) for delivering information (for example, monitoring data) is proposed. The information is collected (235) on a central server (110) from remote sources (105), in order to be provided to multiple clients (120) in response to corresponding requests. In the method of the invention, an interest index is calculated (280) according to the number of preceding requests of the information that have been submitted in the past (so as to estimate the interest of the clients for the information); moreover, a significance index is calculated (220) according to a probability of a current value of the information that is uploaded onto the server by the corresponding source (so as to estimate its importance for the clients). A frequency for refreshing the information on the server can then be determined (245) according to both the interest index and the significance index. In this way, the refresh frequency self-adapts to the expected behavior of the clients.
