Abstract

In various embodiments, methods and systems for managing wake-enabled transport connections of wake-enabled applications is provided. A set of ports is designated as a wake-enabled port set. An operating system (OS) of a computing device running applications plumbs the multiport wake pattern to the one or more network interface controllers (NIC) of the computing device. A wake-enabled application acquires a port from the wake-enabled port set. The OS makes a determination that the application is wake-enabled and as such, assigns a port, from the wake-enable port set, to the wake-enabled application. Upon receiving a packet at the NIC, a determination is made whether the packet corresponds to a wake-enabled transport connection based on comparing the packet to the multiport wake pattern. Upon matching the packet to the multiport wake pattern, the NIC communicates with the OS to wake a portion of the wake-enabled application associated with the wake-enabled transport connection.

Claims

1. One or more computer-readable media storing computer-useable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform a method for managing wake-enabled applications, the method comprising:

receiving a packet;

determining that the packet corresponds to a wake-enabled transport connection of a wake-enabled application, based on comparing the packet to a multiport wake pattern, wherein the multiport wake pattern includes a wake-enabled port set; and

waking at least a portion of the wake-enabled application associated with the wake-enabled transport connection.

2. The media of claim 1, wherein the packet is received when the wake-enabled application is in a suspended state.

3. The media of claim 1, wherein a port of the wake-enabled transport connection is assigned from the wake-enabled port set to the wake-enabled transport connection when creating the wake-enabled transport connection.

4. The media of claim 1, wherein the multiport wake pattern is plumbed as a bit pattern with a mask, wherein the multiport wake pattern is a single bit pattern that supports wake functionality for multiple source ports in the wake-enabled port set.

5. The media of claim 4, wherein comparing the packet to a multiport wake pattern comprises:

identifying a port in the packet; and

matching the port in the packet to a port in the multiport wake pattern using bit masks of the multiport wake pattern that match the entire set of the wake-enabled port set.

6. The media of claim 4, wherein the wake-enabled port set is a non-contiguous port range.

7. The media of claim 4, wherein the wake-enabled port set is a contiguous port range.

8. The media of claim 4, wherein a selected port set from the set of wake-enabled port sets is selected for one of the following:

a user;

a process; and

an application.

9. The media of claim 1, wherein waking at least a portion of the wake-enabled application comprises transitioning the wake-enabled application from a suspended state to an active state.

10. A system for managing wake-enabled applications, the system comprising:

an operating system configured for;

reserving a reserved port set having a wake-enabled port set and a non-wake-enabled port set;

assigning a port from the reserved port set; and

plumbing a multiport wake pattern that includes the wake-enabled port set, wherein the multiport wake pattern supports wake functionality for multiple source ports in the wake-enabled port set;

a multiport wake pattern component having a network interface controller, the multiport wake pattern configured for;

receiving a packet;

determining that the packet corresponds to a wake-enabled transport connection of a wake-enabled application, based on comparing the packet to the multiport wake pattern; and

facilitating waking at least a portion of the wake-enabled application associated with the wake-enabled transport connection; and

a wake-enabled application configured for;

receiving a wake command such that at least of portion of the application is awoken.

11. The system of claim 10, wherein the operating system dynamically determines the reserved port set such that the reserved port set is not hardcoded to the operating system.

12. The system of claim 10, wherein the operating system includes a known reserved port set comprising the wake-enabled port set and a non-wake-enabled port set, wherein the operating system configures transport connections for one or more applications not specifically bound to a port number.

13. The system of claim 10, wherein the operating system supports a plurality of network interface controllers, wherein each of the network interface controllers is plumbed with the multiport wake pattern.

14. The system of claim 10, wherein the multiport wake pattern component is further configured for:

supporting a plurality of internet protocol (IP) addresses, wherein a first IP address supports one or more specific-bind wake-enabled applications and a second IP address supports one or more dynamic-bind wake-enabled applications, and wherein the second IP address supports multiport wake patterns.

15. The system of claim 10, the multiport wake pattern component is further configured for:

delivering the packet to the operating system such that the wake-enabled application is woken; and

the operating system is further configured for;

waking at least a portion of the wake-enabled application associated with wake-enabled transport connection that uses a port matched in the multiport wake pattern; and

queuing the packet for delivery to the transport connection.

16. The system of claim 10, wherein the operating system is further configured for:

assigning the port from the wake-enabled port set when it is determined that the transport connection is wake-enabled; and

assigning the port from the non-wake-enabled port set when it is determined that the transport connection is not wake-enabled.

18. The method of claim 16, wherein the multiport wake pattern is plumbed as a bit pattern, having bit masks, to each of a plurality of network interface controllers such that a single wake slot of each of the plurality of network interface controllers supports the multiport wake pattern.

19. The method of claim 18, wherein the multiport wake pattern is constructed such that a local and remote internet protocol (IP) addresses and the remote port are not included in the pattern.

20. The method of claim 19, wherein the wake-enabled port set is selected such that the start of the range has the least significant 8 bits set to zero.

17. A computer-implemented method for managing wake-enabled transport connections of wake-enabled applications based on multiport wake patterns, the method comprising:

waking at least a portion of the wake-enabled application associated with the wake-enabled transport connection, wherein waking the wake-enabled application comprises;
