Abstract:
1. A method for reducing power consumption in a network switch, comprising: detecting by a controller circuit of the network switch a traffic load on a network link system coupled to the network switch by calculating a sum en-queue rate of the network switch, the sum en-queue rate being a sum of averaged counts of queues in the network switch, the network switch including a first power consumption configuration providing a first link capacity for the network link system, and a second power consumption configuration that is lower than the first power consumption configuration and providing a second link capacity that is lower than the first link capacity; determining by the controller circuit whether the traffic load on the network link system is lower than a first boundary threshold; and reconfiguring by the controller circuit the network switch from the first power consumption configuration into the second power consumption configuration if the traffic load is lower than the first boundary threshold.
