Abstract

A method for directly transferring data between devices includes, with a first computing system that is able to wirelessly associate with a computer network, establishing a direct data-link layer connection to a second computing system that is acting as a data sink, and with the first computing system transmitting data to the second computing system over the connection without transferring the data over the network.

Claims

1. A method for directly transferring data between computing devices, the method comprising:

in response to a determination that a first computing system is not on the same computing network with which a second computing system is currently associated, determining if the first computing system can communicate directly with the second computing system; and

in response to a determination that the first computing system can communicate directly with the second computing system, establishing a wireless, direct data-link layer connection to the second computing system,

wherein the first computing system transmits data to the second computing system over the direct data-link layer connection without transferring the data over the network or interacting with any other computing device.

2. The method of claim 1, wherein the connection between the first computing system and the second computing system is defined by 802.11u networking standard.

3. The method of claim 1, wherein the connection utilizes Generic Advertisement Service (GAS) exchanges.

4. The method of claim 1, wherein the connection utilizes customized network packets.

5. The method of claim 1, further comprising:

determining a media access control (MAC) address of the first computing system;

determining whether the MAC address identifies a device included in a list of devices allowed to transmit data to the second computing system; and

in response to a determination that the MAC address of the first computing device does identify a device included in the list of devices allowed to transmit data to the second computing system, transmitting data between the first computing system and the second computing system over the direct data-link layer connection.

6. The method of claim 1, further comprising:

establishing a direct data-link layer connection to the second computing system in response to the second computing system acknowledging that the first computing system passes a security check, wherein the security check comprises;

with an application installed on the first computing system, managing creation of the direct data-link layer connection to the second computing system,

wherein the application allows for the creation of the direct data-link layer connection with the second computing system.

7. The method of claim 6, wherein the application uses customized packet frames in order to establish the direct data-link layer connection with the second computing system, the customized packet frames being structured for the application.

8. A computing system acting as a data source, the system comprising:

at least one processor;

a memory communicatively coupled to the at least one processor, the memory comprising computer executable code that, when executed by the at least one processor, causes the at least one processor to;

establish a direct data-link layer connection to a data sink device, the computing system being located on a first network and the data sink device being located on a second network; and

transmit data between the computing system and the data sink device over the direct data-link layer connection without involving network stacks of the first network and the second network.

9. The system of claim 8, wherein establishing a direct data-link layer connection to the data sink device comprises with an application running on the computing system, sending a number of customized packet frames to the data sink device, the customized packet frames being structured to be handled by the data sink device.

10. The system of claim 8, wherein the first computing system maintains a connection to the first network while transmitting the data to the data sink device.

11. The system of claim 8, wherein the data sink device allows communication between a list of computing systems, wherein the data sink device determines whether the first computing system is included in the list.

12. The system of claim 8, further comprising computer executable code that, when executed by the at least one processor, causes the at least one processor to:

determine whether the computing system is on the same computing network with which the data sink device is currently associated;

in response to a determination that the computing system is not on the same computing network with which the data sink device is currently associated, determining if the computing system can communicate directly with the data sink device; and

in response to a determination that the computing system can communicate directly with the data sink device, establishing the direct data-link layer connection to the data sink device.

13. The system of claim 12, wherein the computing system transmits data to the data sink device over the direct data-link layer connection without transferring the data over the first network or the second network or interacting with any other computing device.

14. The system of claim 8, wherein the data sink device is a printing device.

15. A method for directly transferring data between computing devices, comprising:

in response to a determination that a data sink device is not part of a network associated with a data source device, broadcasting a signal to determine if the data sink device is within a wireless range of the data source device; and

in response to the data sink device acknowledging that the data source device passes a security check, establishing a direct data-link layer connection to the data sink device.

16. The method of claim 15, comprising transmitting data between the data source device and the data sink device over the direct data-link layer connection without transferring the data over the network.

17. The method of claim 15, wherein the security check comprises:

determining a media access control (MAC) address of the data source device;

determining whether the MAC address identifies a device included in a list of devices allowed to transmit data to the data sink device; and

in response to a determination that the MAC address of the data source device does identify a device included in the list of devices allowed to transmit data to the data sink device, transmitting data between the data source device and the data sink device over the direct data-link layer connection.

18. The method of claim 15, wherein the security check comprises:

with an application installed on the data source device, managing creation of the direct data-link layer connection to the data sink device,

wherein the application allows for the creation of the direct data-link layer connection with the data sink device.

19. The method of claim 15, wherein the application uses customized packet frames in order to establish the direct data-link layer connection with the data sink device, the customized packet frames being structured for the application.

20. The method of claim 15, wherein the data source device transmits data to the data sink device over the direct data-link layer connection without transferring the data over the network associated with the data source device or interacting with any other computing device.
