Abstract

A method, device, and system for delaying delivery of incoming packets during a network-triggered wake of a host computing device includes receiving one or more packets from a remote computing device over a network. The host computing device holds or buffers incoming packets to delay delivery while one or more components transition from a low-power power-managed state to an operational power-managed state. The host computing device may hold and release the packets after passage of a reference time. Additionally, the host computing device may hold and release, buffer and inject, or buffer and replay the packets upon receiving notification that one or more components has transitioned from a low-power state to an operational state. The delayed packets may be acknowledged to the remote computing device to reduce or minimize the overall time needed to establish a connection.

Claims

a processor; and

a memory having stored therein a plurality of instructions that, when executed by the processor, causes the computing device to;

receive a packet from a remote computing device over a network;

initiate a transition from a low-power power-managed state to an operational power-managed state in response to the packet received from the remote computing device;

delay delivery of the packet during the transition from the low-power power-managed state to the operational power-managed state for a reference amount of time, wherein the reference amount of time comprises an amount of time that is less than a transmission timeout of the remote computing device; and

release the packet after passage of the reference amount of time.

2. The computing device of claim 1, wherein the plurality of instructions, when executed by the processor, further causes the computing device to (i) determine one or more current power-managed states and (ii) generate a notification indicative of completion of the transition from the low-power power-managed state to the operational power-managed state.

3. The computing device of claim 2, wherein the plurality of instructions, when executed by the processor, further causes the computing device to (i) receive the notification indicative of completion of the transition from the low-power power-managed state to the operational power-managed state and (ii) release the packet in response to receiving the notification indicative of the completion of the transition from the low-power power-managed state to the operational power-managed state.

4. The computing device of claim 1, wherein the plurality of instructions, when executed by the processor, further causes the computing device to apply one or more filters to the packet received from the remote computing device to determine whether the packet matches one of a reference type, a reference destination port, or a reference pattern;

and

wherein to initiate a transition from a low-power power-managed state to an operational power-managed state comprises to initiate a transition from a low-power power-managed state to an operational power-managed state as a function of a determination that the packet matches one of the reference type, the reference destination port, or the reference pattern.

5. The computing device of claim 1, wherein the plurality of instructions, when executed by the processor, further causes the computing device to:

receive a second packet from the remote computing device over the network;

delay delivery of the second packet during the transition for the reference amount of time; and

release the second packet after passage of the reference amount of time.

6. The computing device of claim 1, wherein to initiate the transition from the low-power power-managed state to the operational power-managed state comprises to initiate a transition of one or more components of the computing device from a low-power power-managed state to an operational power-managed state without initiation of a transition of other components of the computing device from the low-power power-managed state to the operational power-managed state.

7. One or more non-transitory machine readable media comprising a plurality of instructions stored thereon, which in response to execution by a computing device, cause the computing device to:

receive a packet from a remote computing device over a network;

initiate a transition from a low-power power-managed state to an operational power-managed state in response to the packet received from the remote computing device;

delay delivery of the packet during the transition from the low-power power-managed state to the operational power-managed state for a reference amount of time, wherein the reference amount of time comprises an amount of time that is less than a transmission timeout of the remote computing device; and

release the packet after passage of the reference amount of time.

8. The one or more non-transitory machine readable media of claim 7, wherein the plurality of instructions further cause the computing device to:

determine one or more current power-managed states; and

generate a notification indicative of completion of the transition from the low-power power-managed state to the operational power-managed state.

9. The one or more non-transitory machine readable media of claim 8, wherein the plurality of instructions further cause the computing device to release the packet in response to receipt of the notification indicative of the completion of the transition from the low-power power-managed state to the operational power-managed state.

10. The one or more non-transitory machine readable media of claim 7, wherein the plurality of instructions further cause the computing device to apply one or more filters to the packet received from the remote computing device to determine whether the packet matches one of a reference type, a reference destination port, or a reference pattern;

and

wherein to initiate a transition from a low-power power-managed state to an operational power-managed state comprises to initiate a transition from a low-power power-managed state to an operational power-managed state as a function of a determination that the packet matches one of the reference type, the reference destination port, or the reference pattern.

11. The one or more non-transitory machine readable media of claim 7, wherein the plurality of instructions further cause the computing device to:
