A NETWORK NODE HAVING A POWER SAVING MODE

摘要

A network node has an interface which has different modes of operation, including at least a power saving mode and a normal operating mode. The node has a power saving mode management module for maintaining information about whether the interface is in the power saving mode of operation. The power saving mode management module is able to make available to one or more layers higher than the physical layer of the interface information about whether the interface is in the power saving mode of operation.
