1. A method for power management, comprising:
- operating a first Network Interface Controller (NIC) in a low power mode; and
transitioning the first NIC from the low power mode to a power-up sequence if a sleep packet is not received from a second NIC at the first NIC within a predetermined time threshold.

Abstract
A first Network Interface Controller operates in a low power mode. The first Network Interface Controller transitions from low power mode to a power-up sequence if a sleep packet in not received from a second Network Interface Controller at the first Network Interface Controller within a predetermined time threshold.

10. A Network Interface Controller (NIC), comprising:
-
a memory for storing firmware configured to operate the NIC; a bus communicatively coupled to the memory for data transfers within the NIC; a processor communicatively coupled to the bus for executing the firmware; a transceiver communicatively coupled to the bus for sending data from the NIC and receiving data to the NIC; and an Ethernet port communicatively coupled to the bus for providing a physical data interface between the NIC and an Ethernet network, wherein the firmware is configured to perform a method for power management of the NIC, the method comprising; operating the NIC in a low power mode, and transitioning the NIC from the low power mode to a power-up sequence if a sleep packet is not received from a second NIC at the NIC within a predetermined time threshold. - View Dependent Claims (11, 12, 13, 14)
