Abstract

In an example, there is disclosed a system and method for providing a service-oriented architecture, including request/response, over a publish/subscribe framework. In one embodiment, a system is disclosed for adding layers upon a publish/subscribe messaging framework for sophisticated messaging such as point-to-point (request/response) and the ability to query for available services, in a reliable, scalable manner.

Claims

1. One or more non-transitory computer-readable storage mediums having stored thereon executable instructions for providing a data exchange layer (DXL) broker, the executable instructions operable to instruct a processor to:

provide a DXL bus controller configured to provide a DXL fabric, wherein the DXL fabric is configured to provide a request-response framework on a publish-subscribe fabric;

communicatively couple to an enterprise service bus via the DXL bus controller;

receive a service registration message on the enterprise service bus;

determine that the service registration message is for an unregistered service;

create a new service registry record for the service; and

create an instance of the service in the service registry record.

2. The computer-readable medium of claim 1, wherein the instructions are further operable to determine that the service registration message is for a registered service, and to create a new instance of the service in an existing service registry record.

3. The computer-readable medium of claim 1, wherein the instructions are further operable to determine that a service has unregistered, and to remove an instance of the service from an existing service registry record.

4. The computer-readable medium of claim 1, wherein the instructions are further operable to:

receive a service request message on the enterprise service bus; and

determine that the service request is directed to a service for which a service registry record exists, and forward the service request to a device providing the service.

5. The computer-readable medium of claim 1, wherein the instructions are further operable to determine that the service request is directed to a service for which a service registry record does not exist, and to respond with a message that the service is unavailable.

6. The computer-readable medium of claim 1, wherein the instructions are further operable to determine that a plurality of instances of the service are available, and to return a list of available instances.

7. The computer-readable medium of claim 1, wherein the service registry record is configured to include an array of available instances of the service.

8. A data exchange layer (DXL) broker comprising:

a processor;

a network interface configured to communicatively couple the processor to a DXL enterprise service bus; and

a memory having stored thereon executable instructions operable to instruct the processor to;

provide a DXL bus controller configured to provide a DXL fabric, wherein the DXL fabric is configured to provide a request-response framework on a publish-subscribe fabric;

communicatively couple to an enterprise service bus via the DXL bus controller;

receive a service registration message on the enterprise service bus;

determine that the service registration message is for an unregistered service;

create a new service registry record for the service; and

create an instance of the service in the service registry record.

9. The DXL broker of claim 8, wherein the instructions are further operable to determine that the service registration message is for a registered service, and to create a new instance of the service in an existing service registry record.

10. The DXL broker of claim 8, wherein the instructions are further operable to determine that a service has unregistered, and to remove an instance of the service from an existing service registry record.

11. The DXL broker of claim 8, wherein the instructions are further operable to:

receive a service request message on the enterprise service bus; and

determine that the service request is directed to a service for which a service registry record exists, and forward the service request to a device providing the service.

12. The DXL broker of claim 8, wherein the instructions are further operable to determine that the service request is directed to a service for which a service registry record does not exist, and to respond with a message that the service is unavailable.

13. The DXL broker of claim 8, wherein the instructions are further operable to determine that a plurality of instances of the service are available, and to return a list of available instances.

14. The DXL broker of claim 8, wherein the service registry record is configured to include an array of available instances of the service.

15. A method of providing DXL broker services, comprising:

providing a DXL bus controller configured to provide a DXL fabric, wherein the DXL fabric is configured to provide a request-response framework on a publish-subscribe fabric;

communicatively couple to an enterprise service bus via the DXL bus controller;

receiving a service registration message on an enterprise service bus;

determining that the service registration message is for an unregistered service;

creating a new service registry record for the service; and

creating an instance of the service in the service registry record.

16. The method of claim 15, further comprising determining that the service registration message is for a registered service, and to create a new instance of the service in an existing service registry record.

17. The method of claim 15, further comprising determining that a service has unregistered, and removing an instance of the service from an existing service registry record.

18. The method of claim 15, further comprising:

receiving a service request message on the enterprise service bus; and

determining that the service request is directed to a service for which a service registry record exists, and forwarding the service request to a device providing the service.

19. The method of claim 15, further comprising determining that the service request is directed to a service for which a service registry record does not exist, and responding with a message that the service is unavailable.

20. The method of claim 15, further comprising determining that a plurality of instances of the service are available, and returning a list of available instances.
