Abstract

A system and method for enabling legacy media access control (MAC) to do energy efficient Ethernet (EEE). A backpressure mechanism is included in an EEE enhanced PHY that is responsive to a detected need to transition between various power modes of the EEE enhanced PHY. Through the backpressure mechanism, the EEE enhanced PHY can indicate to the legacy MAC that transmission of data is to be deferred due to a power savings initiative in the EEE enhanced PHY.

Description

technical field [0001] The present invention relates to Ethernet systems, and more particularly, to a system and method for enabling energy efficient Ethernet (EEE) operation of a legacy media access controller (MAC). Background technique [0002] The cost of electricity continues to rise, and this trend has developed rapidly in recent years. In this context, many industries have become very sensitive to the impact of these rising costs. In this regard, one area that has received increasing attention in Chengdu is the field of IT architecture. Many companies closely monitor the power usage of their IT systems to see if power costs can be reduced. For this reason, there has emerged an industry focused on energy efficient networking, the entire purpose of which is to address the ever-increasing costs associated with the use of IT equipment (i.e. PCs, monitors, printers, servers, network equipment, etc.) problems caused. [0003] When designing an energy-efficient solution,...
