Embodiment Construction

[0021]Certain embodiments of the invention can be found in a method and system for managing energy efficiency of a network link via pluggable transceiver modules in an energy efficient network device. An Ethernet network may comprise one or more link partners that may be coupled via an Ethernet link. The one or more link partners may comprise one or more pluggable PHY devices. The pluggable PHY devices and / or higher layer devices may be operable to determine one or more energy efficient network control policies that may specify a power level mode for the one or more link partners, and the one or more link partners may be configured to operate in the specified power level mode. In various embodiments of the invention, a power level mode of operation may be selected based on the energy efficient network control policies. Accordingly, one or more components of the pluggable PHY devices may be reconfigured based on the selected power level mode of operation. A first portion of the one o...

Abstract

An Ethernet network may comprise link partners that may be coupled via an Ethernet link. The link partners may comprise pluggable PHY devices. The pluggable PHY devices and / or other link partner devices may determine energy efficient network (EEN) control policies, may select a power level mode and may configure the link partners to operate in the power level mode. Some components may be reconfigured prior to sending an energy efficient network control signal to a link partner and configuring remaining components. Hardware, software and / or firmware may execute the pluggable PHY energy efficient network control policies. Packet data pending delivery may be buffered in the pluggable PHY. The pluggable PHY devices may comprise a MAC and / or a SERDES device. Exemplary form factors for the pluggable PHYs may comprise a SFP, a SFP+, a XENPAK, a X2, a XFP and / or a XPAK. Low power idle mode and / or sub-rate mode may be utilized.
