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.

determining that the packet corresponds to a wake-enabled transport connection of a wake-enabled application, based on identifying that a port in the packet matches a port in the wake-enabled port set, wherein the multiport wake pattern is a wild card pattern corresponding to the wake-enabled port set comprising a plurality of ports, and the plurality of ports are assigned to wake-enabled applications to support wake functionality via the network controller interface based on the multiport wake pattern and corresponding ports of the wake-enabled applications; and

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

identifying the port and an IP address in the packet; and

matching the port and the IP address to the wake-enabled transport connection that uses a port matched in the wake-enabled port set via the multiport wake pattern.

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 assigned as a bit pattern with a mask, wherein the multiport wake pattern is a single bit pattern supporting wake functionality for multiple source ports in the wake-enabled port set.

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

identifying the port in the packet; and

matching the port in the packet to a port in the wake-enabled port set associated with the multiport wake pattern using bit masks of the multiport wake pattern, the multiport wake pattern based on the bit masks is matchable to an 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 or port set from the set of 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 a portion of the wake-enabled application comprises transitioning the wake-enabled application from a suspended state to an active state.

10. A system to manage wake-enabled applications, the system comprising:

a processor and a memory configured for providing computer program instructions to the processor;

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

assign a port from the reserved port set; and

assign a multiport wake pattern corresponding to the wake-enabled port set, wherein the multiport wake pattern is a wild card pattern supporting wake functionality for multiple source ports in the wake-enabled port set, the wake-enabled port set is assigned to a network controller interface as a wake pattern through the multiport wake pattern;

receive a packet;

determine that the packet corresponds to a wake-enabled transport connection of a wake-enabled application, based on identifying that a port in the packet matches a port in the wake-enabled port set; and
