Abstract

Methods and apparatus relating to power management of periodic transmissions from networking applications are described. In one embodiment, a periodic transmission manager coupled between one or more network applications and one or more network interfaces may control the flow of periodic transmissions from the one or more network applications to the one or more network interfaces. Other embodiments are also disclosed.

Claims

1. An apparatus comprising:

a periodic transmission manager coupled between one or more network applications and one or more network interfaces to control transmission of data from the one or more network applications to the one or more network interfaces; and

a storage unit to store policy data accessible by the periodic transmission manager, wherein the policy data is to indicate how frequently each of the one or more network applications are to cause a suspend action or resume action in the one or more network interfaces, wherein the periodic transmission manager is to determine, based on the policy data, when periodic transmissions generated by the one or more network applications are to be transmitted to the one or more network interfaces to cause the suspend action or the resume action.

2. The apparatus of claim 1, further comprising a communication link to directly transmit non-periodic transmissions generated by the one or more network applications to the one or more network interfaces.

3. The apparatus of claim 1, wherein the storage unit is to store data corresponding to one or more of:

the one or more network applications or the one or more network interfaces.

4. The apparatus of claim 1, wherein the one or more network applications comprise one or more of:

a voice over Internet Protocol application, a virtual private networking application, or an instant messenger.

5. The apparatus of claim 1, wherein the one or more network interfaces comprise one or more of:

a local area network stack, a wireless local area network stack, or a virtual private networking virtual adapter.

6. The apparatus of claim 1, wherein the storage unit is to store a policy database comprising the policy data.

7. The apparatus of claim 1, wherein the storage unit is to store a log file comprising data corresponding to operations of the periodic transmission manager.

8. The apparatus of claim 1, further comprising a processor coupled to the storage unit.

9. The apparatus of claim 8, wherein the processor comprises a plurality of processor cores.

10. The apparatus of claim 1, wherein the periodic transmission manager is to coordinate transmission of the periodic transmissions, generated by the one or more network applications, in a burst to conserve power.

17. The apparatus of claim 1, wherein the one or more network applications are to comprise one or more of:

a voice over Internet Protocol application, a virtual private networking application, or an instant messenger.

11. A method comprising:

receiving a packet corresponding to a periodic transmission from a network application to a network interface;

determining, at a periodic transmission manager, whether the packet is to be held for a time period based on stored policy data, wherein the policy data is to indicate how frequently the network application is to cause a suspend action or resume action in the network interface; and

transmitting the packet to the network interface in response to a determination that the packet is to be transmitted to the network interface to cause the suspend action or the resume action.

12. The method of claim 11, wherein the determination that the packet is to be transmitted to the network interface is based on an expiration of the time period.

13. The method of claim 11, further comprising storing the policy data in storage unit.

14. The method of claim 11, further comprising directly transmitting non-periodic transmissions generated by the network application to the network interface.

15. The method of claim 11, further comprising adjusting a timer to indicate when the transmitting the packet to the network interface is to occur.

16. The method of claim 15, wherein adjusting the timer comprises one or more of:

adjusting a wake timer or adjusting a count down timer.

18. The method of claim 11, wherein the network application is to comprise one or more of:

a voice over Internet Protocol application or an instant messenger.

19. The method of claim 11, wherein the network interface is to comprise one or more of:

a local area network stack, a virtual private networking virtual adapter, or a wireless local area network stack.

20. The method of claim 11, further comprising the periodic transmission manager coordinating transmission of periodic transmissions, generated by one or more network applications, in a burst to conserve power.
