Abstract
A system and method for managing power consumption on a network interface card involves connecting constantly running clocks to a small amount of logic on the network interface card. The logic is used to monitor activity on the network interface card, and in response to events enable the clocks for functional blocks within the chip, on an as needed basis. Through dynamically controlled clocks, power consumption can be reduced significantly, and the network interface card remains in a state that is able to react efficiently to external events related to transmission of packets, reception of packets and functions related to the management of the network interface.
