Computer-implemented methods for power management of network interface devices are disclosed. Such methods may include dividing a time period into a plurality of time slots, determining an amount of data received by the network interface device during a first of the time slots, and determining whether the amount of data received exceeds a predefined threshold. If the amount of data received exceeds the predefined threshold, then the network interface device is caused to be awake during a subsequent time slot. The network interface device is caused to go to sleep during the subsequent time slot unless the amount of data received exceeds the predefined threshold. A number of the time slots may be defined as wakeup time slots during which the network interface device is awake. The number of time slots during the time period in which one or more packets were received by the network interface device may be compared to the number of wakeup time slots during the time period. Based on the comparison, the number of wakeup time slots may be adjusted for a subsequent time period.
