摘要： Various methods and systems are provided for buffer-batch management for energy efficient networking. In one embodiment, among others, a system includes a host device including an interface with a network. A device driver monitors requests to transmit packets from the host device to the network, buffers the packets in memory of the host device when the host device network interface is estimated to be in a low power mode, and initiates transition of the host device network interface to a full power mode based at least in part upon predefined criteria associated with the buffered packets. The host device network interface may begin transmission of the buffered packets when the host device network interface enters the full power mode. The host device network interface may be a network interface controller such as, e.g., an Ethernet controller configured for Energy Efficient Ethernet operation.

摘要： A NIC of a host system may provide batching services to enable reducing and/or optimizing overall system power consumption. Batching servicing may comprise buffering received packet within the NIC for an extended period of time—longer than buffering time during normal handling of received packets—based on determination that delaying handling of the received packet by the host system is permitted. Delaying handling of received packets may enable at least one component of the host system, such as a processor, utilized during that handling to remain in power saving states. The received packet may comprise a broadcast ARP packet that does not require a response from the host system. Packets buffered in the NIC may be forwarded to the host system when one or more flushing conditions occur. Flushing conditions may comprise reception of unicast packets destined for the host system or broadcast packets requiring response from the host system.
