Abstract

The present invention provides an apparatus and a method for provisioning services that includes configuring one or more different devices. According to a specific embodiment of the present invention, an apparatus for provisioning a service comprises an information model configured to represent a network resource of said network, to represent said service, and to represent the provisioning of said service, and a processor configured to use a subset of business rules and processes, which can be represented in the same information model, to constrain the implementation of said network resource. In accordance with another embodiment of the present invention, an exemplary apparatus and method governs the manner in which a configuration of a network device is to be created, verified, approved, and deployed.

Claims

1. An apparatus for provisioning a service using a network comprising:

an information model configured to represent at least one function of a network resource to provision said service, said information model configured further to represent a relationship between said service and said at least one function, and to represent a subset of policies to govern operations of said network for provisioning said service; and

a processor configured to use a subset of business rules to constrain the implementation of said at least one function of said network resource.

2. The apparatus of claim 1 further comprising a common translation layer to translate a first level of abstraction for said network resource to a second level of abstraction.

3. The apparatus of claim 1 further comprising a common translation layer to translate a first level of abstraction for said network resource to any number of levels of abstraction, wherein said first level includes one or more levels of abstraction.

4. The apparatus of claim 1 wherein said subset includes at least one business rule for constraining configuration of said network resource.

5. The apparatus of claim 1 wherein said subset includes at least one business rule for constraining deployment of said network resource.

6. The apparatus of claim 1 wherein said information model comprises:

a managed entity data structure for representing said network resource;

an upper layer to provide a first level of abstraction for a first portion of said managed entity data structure; and

a lower layer to provide a second level of abstraction for a second portion of said managed entity data structure.

7. The apparatus of claim 6 wherein said first level of abstraction is associated with said subset of business rules and said second level of abstraction is associated with configuration data.

8. The apparatus of claim 1 wherein said information model comprises:

a managed entity data structure for representing said network resource;

a first subset of levels of abstraction associated with a first portion of said managed entity data structure; and

a second subset of levels of abstraction associated with a second portion of said managed entity data structure.

9. The apparatus of claim 8 wherein said first subset of levels of abstraction is associated with said subset of business rules and said second subset of levels of abstraction is associated with configuration data.

10. The apparatus of claim 7 wherein said configuration data includes at least a command to perform said at least one function of said network resource.

11. The apparatus of claim 6 wherein said information model further comprises another managed entity data structure for representing another network resource.

12. The apparatus of claim 11 wherein said managed entity data structure and said another managed entity data structure include a first role and a second role, respectively.

13. The apparatus of claim 11 wherein said another network resource is a user authorized to implement said network resource.

14. The apparatus of claim 1 wherein said information model is a directory enabled network-next generation (“

DEN-ng”

) information model.

15. A computer-implemented method for provisioning a service using a network, the method comprising:

receiving an input by a user to provision a service; and

selecting a subset of network resources to provide said service based on a subset of business rules and one or more network policies,

wherein at least two of said subset of network resources are different functions.

16. The method of claim 15 wherein said different functions are provided by the same device.

17. The method of claim 15 wherein said different functions are provided by different devices.

18. The method of claim 15 wherein selecting said subset of network resources comprises:

forming a first representation of a network resource independent of an implementation as defined by any vendor;

forming a second representation of said network resource dependent on said implementation as defined by a vendor; and

translating said input associated with said first representation into said second representation to implement said network resource for provisioning said service.

19. The method of claim 18 wherein said first representation is a first portion of a managed entity in an upper layer of an information model and said second representation is a second portion of said managed entity in a lower layer.

20. The method of claim 19 wherein said first portion includes a first subset of attributes defined by a standards-based information model and said second portion includes a second subset of characteristics dependent on said vendor, wherein said second subset inherits said first subset of attributes.

21. The method of claim 20 wherein said standards-based information model is a directory enabled network-next generation (“

DEN-ng”

) information model.

22. The method of claim 18 wherein translating said input further includes identifying a subset of commands to configure each of said subset of network resources.

23. The method of claim 15 wherein selecting said subset of network resources comprises:

organizing physical and logical characteristics of each of said subset of network resources as a tuple; and

using said tuple as a normalized representation for identifying network resources of said subset having similar physical and logical characteristics.

24. A computer-implemented method for provisioning a service using a network, the method comprising:

modeling a number of network resources to represent knowledge information of each network resource of said number of network resources, said knowledge information including physical and logical characteristics associated with each said network resource of said number; and

organizing said physical and logical characteristics as a tuple.

25. The method of claim 24 wherein said physical and logical characteristics include vendor, type of device, product family, model of device, and operating system.

26. The method of claim 24 further comprising identifying a subset of network resources to provide said service, wherein at least two of said subset of network resources are different devices.

27. The method of claim 26 further comprising:

modeling said service to represent relationships to the functions of said network resources;

selecting said service via a user interface; and

translating an object representing one of said different devices at a high-level of abstraction to another object representing said one of said different devices at a low-level of abstraction,

wherein said relationships are modeled using an information model.

28. The method of claim 27 wherein said high-level of abstraction includes a first role and said low-level of abstraction includes a second role.

29. The method of claim 28 wherein said first role is used to authorize deployment of said service and said second role is used to authorize configuration of said one of said different devices.

30. The method of claim 27 wherein said low-level of abstraction is associated with a vendor-specific command.

31. The method of claim 30 wherein said command is chosen based on said tuple.

32. The method of claim 24 wherein said knowledge information is represented by an XML Schema Definition (“

XSD”

) data model.
