Location services on a data exchange layer
There is disclosed in one example a computing apparatus, including: a hardware platform including a processor and a memory; a network interface to communicatively couple to an enterprise service bus (ESB); instructions encoded within the memory to provide a data exchange layer (DXL) application programming interface (API), the DXL API to provide communication with a plurality of other DXL endpoints via a DXL broker; and instructions encoded within the memory to provide an asset management engine to: subscribe to a DXL location services topic via the DXL broker; receive a DXL location services query from a DXL endpoint via the DXL broker; and publish network location data via the DXL broker.
1. A computing apparatus, comprising:
a hardware platform comprising a processor and a memory;
a network interface to communicatively couple to an enterprise service bus (ESB);
instructions encoded within the memory to provide a data exchange layer (DXL) application programming interface (API), the DXL API to provide communication with a plurality of other DXL endpoints via a DXL broker; and
instructions encoded within the memory to provide an asset management engine to:
subscribe to a DXL location services topic via the DXL broker;
receive a DXL location services query from a DXL endpoint via the DXL broker; and
publish network location data via the DXL broker.
2. The computing apparatus of claim 1 , wherein the network location data comprise logical network location data.
3. The computing apparatus of claim 1 , wherein the network location data comprise physical network location data.
4. The computing apparatus of claim 1 , wherein publishing network location data comprises:
receiving information about the DXL endpoint via a DXL query;
determining a logical location of the DXL endpoint based on the information about the DXL endpoint; and
publishing a DXL response comprising the logical location.
5. The computing apparatus of claim 4 , wherein a topic of the DXL response is a private destination topic of the DXL endpoint.
6. The computing apparatus of claim 1 , further comprising a physical network topology engine operable for mapping physical network locations.
7. The computing apparatus of claim 1 , wherein the asset management engine further comprises instructions to interoperate with a physical network topology engine configured to map physical network locations.
8. The apparatus of any claim 1 , wherein the asset management engine is further to:
subscribe to a DXL device detected topic;
receive a DXL device detected message comprising an identifier for a detected device and an identifier for a broker for the detected device;
build a list of switches to the detected device; and
build a logical location of the detected device.
9. The computing apparatus of claim 8 , wherein the asset management engine is further to publish the logical location of the detected device as a detected device DXL message.
10. The computing apparatus of claim 1 , wherein the asset management engine is further to provide both logical and physical location services.
11. The computing apparatus of claim 10 , wherein the asset management engine is further to receive manual user input for updating the location services.
12. The computing apparatus of claim 1 , wherein the DXL API is configured to act as a producer in a DXL producer-consumer architecture.
13. The computing apparatus of claim 12 , wherein the DXL API is configured to act as a producer of DXL location services messages.
14. One or more tangible, non-transitory computer-readable storage media having stored thereon executable instructions to:
communicatively couple to a data exchange layer (DXL) broker;
send a DXL message to the DXL broker to subscribe to a DXL location services topic;
receive a DXL message comprising a location services query; and
send to the DXL broker a DXL message comprising network location data.
15. The one or more tangible, non-transitory computer-readable media of claim 14 , wherein the network location data comprise logical network location data.
16. The one or more tangible, non-transitory computer-readable media of claim 14 , wherein the network location data comprise physical network location data.
17. The one or more tangible, non-transitory computer-readable media of claim 14 , wherein the instructions are further to publish network location data, comprising:
receiving information about a DXL endpoint via a DXL query;
determining a logical location of the DXL endpoint based on the information about the DXL endpoint; and
publishing a DXL response comprising the logical location with a private destination topic of the DXL endpoint.
18. The one or more tangible, non-transitory computer-readable media of claim 14 , wherein the instructions are further to interoperate with a physical network topology engine configured to map physical network locations.
19. The one or more tangible, non-transitory computer-readable media of claim 18 , wherein the asset management engine is further to:
subscribe to a DXL device detected topic;
receive a DXL device detected message comprising an identifier for a detected device and an identifier for a broker for the detected device;
build a list of switches to the detected device; and
build a logical location of the detected device.
20. The one or more tangible, non-transitory computer-readable media of claim 19 , wherein the asset management engine is further to publish the logical location of the detected device as a detected device DXL message.
