Method for reducing energy consumption in packet processing line cards

摘要

The present invention refers to a method for reducing energy consumption in a packet processing linecard of a packet transmission network, said packet processing linecard comprising a plurality of microprocessors aimed at processing packet traffic wherein the number of active microprocessors is dynamically adjusted as a function of the computation of a traffic estimator based on a recurrent estimation of at least two statistical parameters including the average and a parameter representative of the statistical distribution of the packet traffic.
