Abstract: Various systems and methods for implementing protocol state aware power management are described herein. A network interface device for implementing protocol state aware power management includes circuitry to provide a direct memory access interface; medium access control (MAC) circuitry to interface with a network; and control circuitry to: classify packets received at the MAC circuitry as packets used to open network connections or packets used to close network connections; maintain statistics of packets used to open network connections and packets used to close network connections; calculate a power hint based on the statistics of packets used to open connections and packets used to close network connections; and write a receive descriptor to a host memory using the direct memory access interface, the receive descriptor including a power hint field with the power hint, the power hint used by a host processor to scale processor power based on the power hint.
