Abstract

Methods, systems, and products translate addresses in residential networks. A residential gateway translates requests for content such that the residential gateway appears as both a requestor and a destination for requested content, regardless of an actual requesting device or a desired output device.

Claims

1. A method, comprising:

receiving, at a processor, a request for content sent from a requesting address of a requesting device, the request for the content specifying a different output device to which the content is delivered;

storing, in memory, an association between the request for the content, the requesting address, and a destination address of the different output device;

generating, by the processor, a translated request that identifies a gateway network address as both a requestor and a destination for the content; and

sending, by the processor, the translated request for the content.

2. The method of claim 1, further comprising receiving the content.

3. The method of claim 1, further comprising receiving the content addressed to the gateway network address.

4. The method of claim 1, further comprising retrieving the destination address associated with the different output device.

5. The method of claim 1, further comprising sending the content to the destination address associated with the different output device.

6. The method of claim 1, further comprising receiving a selection of the different output device in a graphical listing of output devices.

7. The method of claim 6, further comprising populating the graphical listing with the output devices.

8. A system, comprising:

a processor; and

a memory storing instructions that when executed causes the processor to perform operations, the operations comprising;

receiving a request for content sent from a requesting address of a requesting device, the request for the content specifying a different output device to which the content is delivered;

storing an association between the request for the content, the requesting address, and a destination address of the different output device;

generating a translated request that identifies a gateway network address as both a requestor and a destination for the content; and

sending the translated request for the content.

9. The system of claim 8, wherein the operations further comprise receiving the content.

10. The system of claim 8, wherein the operations further comprise receiving the content addressed to the gateway network address.

11. The system of claim 8, wherein the operations further comprise retrieving the destination address associated with the different output device.

12. The system of claim 8, wherein the operations further comprise sending the content to the destination address associated with the different output device.

13. The system of claim 8, wherein the operations further comprise receiving a selection of the different output device in a graphical listing of output devices.

14. The system of claim 8, wherein the operations further comprise populating the graphical listing with the output devices.

15. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:

receiving a request for content sent from a requesting address of a requesting device, the request for the content specifying a different output device to which the content is delivered;

storing an association between the request for the content, the requesting address, and a destination address of the different output device;

generating a translated request that identifies a gateway network address as both a requestor and a destination for the content; and

sending the translated request for the content.

16. The memory of claim 15, wherein the operations further comprise receiving the content.

17. The memory of claim 15, wherein the operations further comprise receiving the content addressed to the gateway network address.

18. The memory of claim 15, wherein the operations further comprise retrieving the destination address associated with the different output device.

19. The memory of claim 15, wherein the operations further comprise sending the content to the destination address associated with the different output device.

20. The memory of claim 15, wherein the operations further comprise receiving a selection of the different output device in a graphical listing of output devices.
