Power consumption management in a network device

摘要

An initial amount of data transmitted from a MAC (12) is buffered in a PHY buffer (25). Depending on the speed at which the PHY buffer fills up relative to the time remaining for the far-end PHY (66) to transition from a second to a first far-end PHY power state the PHY does or does not transmit a data delay indicator (50) to MAC to preempt the MAC from transmitting the remaining amount of data.
