1. An energy efficient Ethernet method, comprising:
- receiving, from a link partner on a port, an identifier of a device;
retrieving energy saving profile information for said device from a database using said received identifier, wherein said retrieving comprises retrieving work schedule information for said device;
analyzing link utilization information for said link in combination with said retrieved energy saving profile information; and
switching elements of said port into a power saving state based on a result of said analysis.

Abstract
A system and method for dynamic energy efficient Ethernet (EEE) control policy based on user or device profiles and usage parameters. The analysis by an EEE control policy can consider user or device related EEE profile information that is either network propagated or retrieved from a network database. This EEE profile information can be used in combination with static settings established by an IT manager and the properties of the traffic on the link itself.

4. An energy efficient Ethernet method, comprising:
-
receiving a packet from a link partner; retrieving energy saving classification information from said packet, wherein said energy saving classification information is based on work schedule information for a device that originated said packet; analyzing, by an energy efficiency control policy, link utilization information for said link in combination with said retrieved energy saving classification information to produce an energy efficiency control signal; and switching elements of a port interfaced with said link partner into a power saving state based on said energy efficiency control signal. - View Dependent Claims (5, 6)

7. An energy efficient Ethernet method in an Ethernet device, comprising:
-
receiving, via a packet on a port, information that enables identification of an energy saving classification of a user or device, wherein said energy saving classification information is based on work schedule information for a user or device that is associated with an origination of said packet; and determining, by an energy efficiency control policy, whether a port that supports communication associated with said user or device should enter into a power saving state, wherein said determination by said energy efficiency control policy is based on an analysis of link utilization information and said energy saving classification for said user or device. - View Dependent Claims (8, 9, 10, 11)
