Abstract

Connection definitions are centrally defined and distributed over a network. A connection is defined, including information identifying an associated service definition, an associated origination endpoint and an associated destination endpoint within the network. The connection definition is distributed via the network to the origination endpoint and the destination endpoint. The service defined by the service definition is implemented between the origination endpoint and the destination endpoint, and the origination endpoint and the destination endpoint communicate with each other directly over the network in a secure and reliable way.

Claims

1. A method for centrally defining and distributing connection definitions over a network, comprising the steps of:

defining a connection, the connection including information identifying an associated service definition, an associated origination endpoint and an associated destination endpoint within the network;

distributing the connection definition via the network to the origination endpoint and the destination endpoint; and

implementing a service defined by the service definition between the origination endpoint and the destination endpoint, whereby the origination endpoint and the destination endpoint communicate with each other directly over the network in a secure and reliable way.

2. The method of claim 1, wherein the service definition includes a service name, associated inputs, and associated outputs.

3. The method of claim 2, wherein each input or output may be a simple value, an XML document, or an arbitrary binary object.

4. The method of claim 1, wherein an endpoint may be used as an origination endpoint, a destination endpoint, or both simultaneously.

5. The method of claim 1, wherein the step of defining a connection includes:

publishing a service definition by a service publisher at the origination endpoint or the destination endpoint;

inviting participation in the connection for implementing the service by a service subscriber at either the destination endpoint or the origination endpoint, respectively; and

accepting the invitation to participate by the service subscriber at either the destination endpoint or the origination endpoint, respectively.

6. The method of claim 1, further comprising the steps of:

updating the connection definition; and

distributing the updated connection definition to the endpoints via the network.

7. The method of claim 6, wherein the step of updating comprises updating the information identifying the origination endpoint, the destination endpoint, or both.

8. The method of claim 6, wherein the step of updating comprises updating the service defined by the service definition.

9. The method of claim 1, further comprising an initial step of distributing management information to at least one endpoint for managing the definition of connections and the distribution of connection definitions, wherein the management information is also distributed to the other endpoint at the same time or at a later time.

10. The method of claim 8, further comprising:

updating the management information; and

distributing the updated management information to the endpoints.

11. An apparatus for centrally defining and distributing connection definitions over a network, comprising:

a database for storing a connection definition, including information identifying an associated service definition, an associated origination endpoint and an associated destination endpoint within the network; and

distribution means for distributing the connection definition via the network to the origination endpoint and the destination endpoint, wherein a service defined by the service definition is implemented by the origination endpoint and the destination endpoint, such that the origination endpoint and the destination endpoint communicate with each other directly over the network.

12. The apparatus of claim 11, wherein the service definition includes a service name, associated inputs, and associated outputs.

14. The apparatus of claim 11, wherein an endpoint may be used as an origination endpoint, a destination endpoint, or both simultaneously.

15. The apparatus of claim 11, wherein the apparatus defines a connection definition by storing a service definition published by a service publisher at either the origination endpoint or the destination endpoint, storing information indicating an invitation from the service publisher at the origination endpoint or the destination endpoint for participating in a connection for implementing the service to a service subscriber at either the destination endpoint or the origination endpoint, respectively, and storing information indicating acceptance of the invitation by a service subscriber at either the destination endpoint or the origination endpoint, respectively.

16. The apparatus of claim 11, further comprising means for updating the connection definition, wherein the distribution means distributes the updated connection definition to the endpoints.

17. The apparatus of claim 16, wherein the updating means updates the information identifying the origination endpoint, the destination endpoint, or both.

18. The apparatus of claim 16, wherein the updating means updates the service defined by the service definition.

19. The apparatus of claim 11, wherein the distribution means initially distributes management information to at least one endpoint for managing the definition of connections and the distribution of connection definitions, and the distribution means also distributes the management information to the other endpoint at the same time or at a later time.

20. The apparatus of claim 18, further comprising means for updating the management information, wherein the distribution means distributes the updated management information to the endpoints.

13. The apparatus of claim 121, wherein each input or output may be a simple value, an XML document, or an arbitrary binary object.

21. A system for centrally defining and distributing connection definitions over a network, comprising:

an origination endpoint;

a destination endpoint; and

a central server connected via the network to the origination endpoint and the destination endpoint for storing a connection definition including information identifying an associated service definition, the origination endpoint and the destination endpoint within the network and for distributing the connection definition via the network to the origination endpoint and the destination endpoint, wherein a service defined by the service definition is implemented by the origination endpoint and the destination endpoint such that the origination endpoint and the destination endpoint communicate with each other directly over the network.

22. The system of claim 21, wherein the service definition includes a service name, associated inputs, and associated outputs.

23. The system of claim 22, wherein each input or output may be a simple value, an XML document, or an arbitrary binary object.

24. The system of claim 21, wherein an endpoint may be used as an origination endpoint, a destination endpoint, or both simultaneously.

25. The system of claim 21, wherein for defining a connection, a service publisher at either the origination endpoint or the destination endpoint publishes a service definition at the central server and invites the a service subscriber at the other endpoint to participate in the connection to implement the service, and the service subscriber at the other endpoint accepts the invitation to participate.

26. The system of claim 21, wherein the central server updates the connection definition and distributes the updated connection definition to the endpoints.

27. The system of claim 26, wherein the central server updates the information identifying the origination endpoint, the destination endpoint, or both.

28. The system of claim 26, wherein the central server updates the service defined by the service definition.

29. The system of claim 21, wherein the central server initially distributes management information to at least one endpoint for managing the definition of connections and the distribution of connection definitions, and the central server also distributes the management information to the other endpoint at the same time or at a later time.

30. The system of claim 28, wherein the central server updates the management information and distributes the updated management information to the endpoints.
