Abstract

A network management system for implementing a service on a network acquires policy rules for configuring the service, determines commands corresponding to the policy rules and transmits them to network elements, and infers the rules in order to determine the commands. The rules comprise services rules and implementation rules.

Claims

1. A network management system for creating and implementing a service on a network, said network management system comprising:

means for acquiring policy rules comprising service rules which create the service and implementation rules which implement the service;

means for inferring said policy rules to determine commands corresponding to said policy rules; and

means for transmitting the determined commands to network elements of the network,

wherein said implementation rules for implementing the service comprise technology rules and equipment rules,

wherein the inferring means correlates the service rules with the technology rules,

wherein the technology rules determine technology to use in the implementation of the service based on attributes of the service and equipment in the network,

wherein the service is defined by the service rules independently of the technology and specification of the network equipment,

wherein the inferring means adapts the technology rules using the equipment rules based on an equipment type,

wherein the technology rules specify which protocol to use for the service based on the attributes of the equipment in the network,

wherein the equipment rules model how to select the technology rules based on the attributes of the equipment, and

wherein the technology rules are different from the equipment rules.

2. The network management system claimed in claim 1, wherein said inference means comprises an inference engine provided in the network management system and external to the network comprising the network elements.

3. The network management system claimed in claim 1, wherein the service rules are provided externally from the network management system and wherein the service rules specify conditions and timing for creating the service.

4. The network management system claimed in claim 1, wherein the service is designed by a developer independently from specifications of equipment and technology specified in the implementation rules and wherein the implementation rules are dynamically implemented after the determining means determines applicable implementation rules.

5. The network management system claimed in claim 1, wherein the service is designed by an operator without requiring specific knowledge of equipment and technology of the network for the service.

6. The network management system claimed in claim 1, wherein the implementation rules specify implementation specific details of the service.

7. The network management system claimed in claim 1, wherein the implementation rules specify attributes of the service.

8. The network management system claimed in claim 1, wherein the service is a virtual private network.

9. The network management system claimed in claim 1, wherein the technology to be used is determined based on a number of sites involved in a particular network.

10. The network management systems claim in claim 1, wherein the equipment rules model how the technology rules must be selected for the particular equipment type.

11. The network management system claimed in claim 1, wherein the particular equipment type is selected based on their capacity.

12. The network management system claimed in claim 1, wherein the service provides video conferences.

13. The network management system claimed in claim 1, wherein the technology is Internet Protocol Security (IPsec) protocol.

14. The network management system claimed in claim 1, wherein the technology is multi-protocol label switching (MPLS) tunnels.

15. The network management system claimed in claim 1, wherein the equipment is a router.

16. The network management system claimed in claim 1, wherein the network comprises IP routers.

17. The network management system claimed in claim 1, wherein the network comprises asynchronous transfer mode (ATM) switches.

18. The network management system claimed in claim 1, wherein the equipment is an asynchronous transfer mode (ATM) switch.

19. The network management system claimed in claim 1, wherein the particular equipment type is selected based on a manufacturer.

20. The network management system of claim 1, further comprising a first database which stores the technology rules and a second database which stores the equipment rules.
