Abstract

Modifying remote service discovery based on presence involves identifying service discovery data using ad-hoc, peer-to-peer, service discovery protocols of a local network. The service discovery data is aggregated via an entity of the local network. Presence data associated with a remote device located outside of the local network is identified and the aggregated service discovery data is altered based on the presence data. The altered aggregated service discovery data is made available to the remote device using out-of-band communications. The out-of-band communications are different from the service discovery protocols of the local network.

Claims

1. A method comprising:

identifying service discovery data using ad-hoc, peer-to-peer, service discovery protocols of a local network;

aggregating the service discovery data via an entity of the local network;

identifying presence data associated with a remote device located outside of the local network;

altering the aggregated service discovery data based on the presence data; and

making the altered aggregated service discovery data available to the remote device using out-of-band communications, wherein the out-of-band communications are different from the service discovery protocols of the local network.

2. The method of claim 1, wherein the service discovery protocols of the local network comprise Simple Service Discovery Protocol.

3. The method of claim 1, wherein the local network comprises a Universal Plug and Play network.

4. The method of claim 1, wherein the out-of-band communications comprise Web syndication communications.

5. The method of claim 1, wherein identifying the presence data comprises subscribing to presence notification via a presence server located outside of the local network.

6. The method of claim 1, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on a presence state identified via the presence data.

7. The method of claim 6, wherein altering the aggregated service discovery data comprises limiting the visibility of the one or more services based on lack of secure access to the one or more services.

8. The method of claim 6, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services based on limited available network bandwidth of the remote device.

9. The method of claim 6, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services based on monetary costs associated with network bandwidth used by the remote device.

10. The method of claim 6, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services to allow the remote device to conserve power.

11. The method of claim 1, further comprising associating at least one filter with each of a plurality of known presence states, wherein each filter describes services that may be remotely advertised to the remote device based on the presence state associated with the filter.

12. The method of claim 11, wherein altering the aggregated service discovery data based on the presence data comprises:

identifying a presence state based on the presence data, wherein the identified presence state conforms to one of the known presence states;

selecting the filter associated with the identified presence state; and

altering the aggregated service discovery data with the selected filter.

13. The method of claim 1, further comprising communicating the presence data to one or more peer-to-peer devices via the local network.

14. An apparatus comprising:

one or more network interfaces capable of communicating via a local network and a remote network;

a processor coupled to the one or more network interfaces; and

memory coupled to the processor, the memory including instructions that cause the processor to,

identify service discovery data of the local network using an ad-hoc, peer-to-peer, service discovery protocol;

aggregate the service discovery data;

identify, via the remote network, presence data associated with a remote device of the remote network;

alter the aggregated service discovery data based on the presence data; and

make the altered aggregated service discovery data available to the remote device via the remote network using out-of-band communications, wherein the out-of-band communications are different from the service discovery protocols of the local network.

15. The apparatus of claim 14, wherein the service discovery protocol of the local network comprises Simple Service Discovery Protocol.

16. The apparatus of claim 14, wherein the out-of-band communications comprise Web syndication communications.

17. The apparatus of claim 14, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on lack of secure access to the one or more services.

18. The apparatus of claim 14, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on limited available network bandwidth of the remote device identified via the presence data.

19. The apparatus of claim 14, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on monetary costs associated with network bandwidth used by the remote device.

20. The apparatus of claim 14, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network to allow the remote device to conserve power.

21. The apparatus of claim 14, wherein the memory further comprises filter data describing a plurality of filters, wherein at least one of the filters is associated with each of a plurality of known presence states, and wherein each of the filters describes services that may be remotely advertised to the remote device based on the presence state associated with the filter.

22. The apparatus of claim 21, wherein the instructions cause the processor to:

identify a presence state based on the presence data, wherein the identified presence state conforms to one of the known presence states;

select the filter associated with the identified presence state; and

alter the aggregated service discovery data with the selected filter.

23. The apparatus of claim 14, wherein the instructions further cause the processor to communicate the presence data to one or more peer-to-peer devices via the local network.

24. A computer-readable storage medium having instructions stored thereon which are executable by an apparatus capable of being coupled to a local network and a remote network for performing steps comprising:

identifying service discovery data of the local network using an ad-hoc, peer-to-peer, service discovery protocol;

aggregating the service discovery data;

identifying, via the remote network, presence data associated with a remote device of the remote network;

altering the aggregated service discovery data based on the presence data; and

making the altered aggregated service discovery data available to the remote device via the remote network using out-of-band communications, wherein the out-of-band communications are different from the service discovery protocols of the local network.

25. The computer-readable medium of claim 24, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on lack of secure access to the one or more services.

26. The computer-readable medium of claim 24, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on limited available network bandwidth of the remote device identified via the presence data.

27. The computer-readable medium of claim 24, wherein altering the aggregated service discovery data comprises limiting the visibility of one or more services of the local network based on monetary costs associated with network bandwidth used by the remote device.
