1. An energy efficiency method performed by a discovery node in a network, comprising:
- controlling, via an energy efficiency control policy operating in said discovery node, transitions between an energy saving state and an active state of one or more components in said discovery node that support a network link, said energy efficiency control policy receiving as a first input a first measure of a level of utilization of said network link, wherein said energy saving state of said one or more components has a reduced power consumption and reduced data transmission rate as compared to said active state of said one or more components;
transmitting, from said discovery node, discovery traffic to each of a plurality of network nodes that are remote from said discovery node;
generating a second measure of current network performance for each of said plurality of network nodes based on a plurality of reply messages received from said plurality of network nodes in response to said transmitted discovery traffic; and
adjusting an effect of said energy efficiency control policy on said one or more components in said discovery node based on a second input based on said second measure of current network performance for each of said plurality of network nodes.

Abstract
An auto-aware dynamic control policy for energy efficiency. A discovery node in a network can be designed to transmit periodically discovery traffic to a plurality of other network nodes in the network. Responses to the discovery traffic can be used by the discovery node to ascertain real-time activity in the network. Measures of the real-time activity can be used to adjust a control policy in the discovery node.

12. An energy efficiency method performed by a discovery node, comprising:
-
transmitting, from said discovery node, first discovery traffic to each of a first plurality of network nodes, said first discovery traffic designed to test a first level of current network performance of a first type of network traffic; transmitting, from said discovery, node, second discovery traffic to each of a second plurality of network nodes, said second discovery traffic designed to test a second level of current network performance of a second type of network traffic different from said first type of network traffic; generating a first measure of current network performance for each of said first plurality of network nodes based on first reply messages received from said first plurality of network nodes in response to said transmitted first discovery traffic; generating a second measure of current network performance for each of said second plurality of network nodes based on second reply messages received from said second plurality of network nodes in response to said transmitted second discovery traffic; and adjusting an energy efficiency control policy in said discovery node based on said first and second measures of current network performance, said energy efficiency control policy controlling transitions between an energy saving state and an active state of one or more components in said discovery node, wherein said energy saving state of said one or more components has a reduced power consumption and reduced data transmission rate as compared to said active state of said one or more components, wherein said adjusting comprises adjusting a level of aggressiveness of said energy efficiency control policy through an adjustment of a length of a timer that controls at least part of said transitions. - View Dependent Claims (13, 14, 15, 16, 17)
