Patent ID: 7827284

Claim:
A method for performing admission control in order to offer assurances on forwarding quality in networks comprising the steps of: setting a resources requested threshold for each link where said resources requested threshold defines a maximum sum of forwarding resources requested by applications for their application data flows, ADFs, on the link; calculating a measurement level threshold, the measurement level threshold being a rate lower than the resources requested threshold; determining whether a reservation level exceeds the measurement level threshold; upon determining that the reservation level exceeds the measurement level threshold, repeatedly measuring, during usage, multiplexing properties of aggregated ADFs on each link, each measuring being performed over a period of time; dynamically adapting said resources requested threshold by utilizing the measured multiplexing properties of the ADFs on each link and by utilizing knowledge about the forwarding resources of the links; recalculating the measurement level threshold based on the dynamically adapted resources requested threshold; and preventing an overload before it occurs by controlling admission to each link based on the dynamically adapted resources requested threshold.
