Abstract
A method is described and in one embodiment includes, for each of a plurality of outgoing ports of a first network element: collecting data comprising a number of packets arriving the outgoing port and an amount of power consumed by the outgoing port for a first time interval; calculating a packet per watt ('P/W') metric for the port for the first time interval, wherein the P/W metric comprises the number of packets coming into the port divided by the amount of power consumed by the port during the first time interval; repeating the collecting and calculating for a number of successive time intervals; calculating a mean P/W metric for a time period comprising the first time interval and the successive time intervals; and calculating a variance for the time period comprising the first time interval and the successive time intervals. The method further includes redirecting traffic received at the network element to the outgoing port having the lowest variance.
