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 storage media storing computer-readable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform operations for managing wake-enabled applications, the operations 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 comparing the packet to the multiport wake pattern comprises;

identifying a port in the packet; and

matching the port in the packet to the multiport wake pattern using bit masking, wherein the multiport wake pattern is matchable to a plurality of ports in a wake-enabled port set, wherein the multiport wake pattern is a wild card pattern corresponding to the wake-enabled port set comprising the plurality of ports, wherein the multiport wake pattern is a bit pattern supporting wake functionality for multiple source ports in the wake-enabled port set, and the plurality of ports are assigned to wake-enabled applications to support wake functionality; and

waking at least a portion of the wake-enabled application associated with the wake-enabled transport connection based at least in part on the identified port.

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 wake-enabled port from the wake-enabled port set is assigned 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 constructed without a local internet protocol address, a remote internet protocol address, and a remote port.

5. The media of claim 4, wherein the multiport wake pattern is one of a plurality of multiport wake patterns, wherein each multiport wake pattern is assigned to a corresponding configurable slot of a plurality of configurable slots of a network interface controller.

6. The media of claim 1, wherein the wake-enabled port set is a non-contiguous port range.

7. The media of claim 1, wherein the wake-enabled port set is a contiguous port range.

8. The media of claim 1, wherein a selected port or port subset from the wake-enabled port set is selected specifically for one of the following:

a user;

a process; and

an application.

9. The media of claim 1, wherein waking at least the 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:
