Abstract
Aspects of a method and system for supporting a variable and energy efficient data rate using a duty cycling technique and multiple power states on an Ethernet link are provided. In this regard, a data rate on a network link may be duty cycled based on characteristics of data communicated over it. The network link may operate at a first data rate for a first portion of the time interval and may operate at a second data rate for a second portion of the time interval. The duration of each portion of the time interval and/or the data rate during each portion of the time interval may be adjusted to control the duty cycling. Power consumed in a device connected to the network link may be controlled based on the duty cycling of the link.
