  • Power consumption management in a network device
    Patent number: 8448007
    Abstract: A method includes buffering an initial amount of data of a data set transmitted from a MAC. When an amount of time for data associated with the data set to fill a PHY buffer approaches an amount of time for a far-end PHY to transition from a second far-end PHY power mode to a first far-end PHY power state, a remaining amount of data of the data set transmitted from the MAC is buffered and the data is transmitted to the far-end PHY after it transitions to the first far-end PHY power state. When the amount of time for data associated with the data set to fill the buffer exceeds the amount of time for the far-end PHY to transition to the first far-end PHY power state, a data delay indicator is transmitted to the MAC to preempt the MAC from transmitting the remaining amount of data.

When an amount of time for data associated with the data set to fill a PHY buffer approaches an amount of time for the far-end PHY to transition from the second far-end PHY power state to the first far-end PHY power state, buffering a remaining amount of data of the data set transmitted from the MAC and transmitting the data to a far-end PHY after the far-end PHY transitions between a second and first far-end PHY power state. When the amount of time for data associated with the data set to fill the buffer exceeds the amount of time for the far-end PHY to transition from the second to the first far-end PHY power state, transmitting a data delay indicator to the MAC to preempt the MAC from transmitting the remaining amount of data.
