A method for receiving network packets on a client device comprising: initially entering into a first mode of operation in which polling from a network layer to a driver layer is disabled, wherein in the first mode of operations data packets received by the driver layer are pushed up to the network layer; monitoring a load factor defining a current network load on the client device; and entering into a second mode of operation in which polling from the network layer to the driver layer is enabled, wherein when in the second mode of operation, the network layer polling the driver layer when it is ready to accept new packets from the driver layer.

System and method for processing network packets received on a client device using opportunistic polling between networking layers

A machine implemented method includes creating a universally unique identifier, detecting a trigger of a sleep event, and associating the universally unique identifier with the sleep event. The method monitors sub-system events that occur after a sleep event has been triggered and stores data in non-volatile non-disk storage (e.g., non-boot storage) identifying an event stage corresponding to the sub-system event that is occurring. The method determines whether a wake event has completed and logs each of the sub-system events using the universally unique identifier until a wake event has completed.

Sleep wake event logging

A client device having a networking layer and a network driver layer for transmitting network packets comprising: a plurality of transmit queues configured at the network layer, each of the transmit queues having different packet service classifications associated therewith, packets being queued in one of the transmit queues according to traffic service classifications assigned to the packets; a classifier module for classifying packets according to the different packet service classifications, wherein a packet to be transmitted is stored in one of the transmit queues based on the packet service classifications; and a network layer packet scheduler for scheduling packets for transmission from each of the transmit queues at the networking layer, the network layer packet scheduler scheduling packets for transmission according to the packet service classifications.

System and method for performing packet queuing on a client device using packet service classifications

A computer-implemented method for managing packet scheduling on a client device. For example, one embodiment of a method comprises: receiving a packet to be transmitted; enqueuing the packet in a queue at a network stack level; determining whether packet scheduling is currently being performed at a driver level or at a networking stack level; selecting the packet for transmission from the queue at the network stack level if scheduling is currently being performed at the network stack level; and selecting the packet for transmission from the queue at the driver level if scheduling is currently being performed at the driver level.

System and method for scheduling packet transmission on a client device

Exemplary embodiments of methods, apparatuses, and systems for powering up select components of a computer from a sleep state, maintaining a network state, and powering down the select components of the computer to return the computer to the sleep state are described. For one embodiment, a network interface and a fan controller receive power during the network state maintenance but a display or audio components do not receive power during the network state maintenance.
