Abstract

Methods, systems, and computer readable media for multi-layer orchestration in software defined networks (SDNs) are disclosed. In one example, the method includes receiving orchestration related data for implementing a network service using the network resources within the SDN, determining configuration information for the network resources based on the orchestration related data and protocol layer capability of the network resources, wherein determining the configuration information includes identifying the network resources having the protocol layer capability to provide network services, and providing the configuration information to the network resources.

Claims

1. A method for multi-layer orchestration in a software defined network (SDN), the method comprising:

at an orchestrator comprising a hardware processor and for optimizing network resources within an SDN;

receiving orchestration related data for implementing a network service using the network resources within the SDN;

determining configuration information for the network resources based on the orchestration related data and protocol layer capability of the network resources, wherein determining the configuration information includes identifying the network resources having the protocol layer capability to provide network services; and

providing the configuration information to the network resources.

2. The method of claim 1 wherein receiving the orchestration related data comprises receiving the orchestration related data from an operations module.

3. The method of claim 1 wherein receiving the orchestration related data includes receiving at least one of:

network service catalogue information; and

a network service graph.

4. The method of claim 1 wherein determining the configuration information for the network resources comprises analyzing the orchestration related data and the protocol layer capability of the network resources and identifying to which of the network resources to provide the configuration information.

5. The method of claim 4 wherein analyzing the orchestration related data and the protocol layer capability of the network resources comprises applying an algorithm to the orchestration related data and the protocol layer capability of the network resources to determine which of the network resources provide an optimized flow of network traffic.

6. The method of claim 1 wherein the protocol layer capability comprises an ability of a network resource to control network traffic using at least one criterion associated with a particular protocol layer.

7. The method of claim 1 wherein the network resources comprise at least one of a switch, a router, a layer 3 switch, a layer 3 router, a layer 4 router, a layer 7 application server, a layer 7 router, a controller, and another network element.

8. The method of claim 1 wherein providing the configuration information to the network resources comprises automatically orchestrating connections between the network resources.

9. The method of claim 8 wherein automatically orchestrating the connections between the network resources comprises automatically orchestrating a connection between a layer n network resource and at least one layer m network resource, where n and m are integers and n is different from m.

10. The method of claim 9 wherein automatically orchestrating the connections between the network resources comprises automatically orchestrating a connection between a layer 7 router and at least one layer 4 router.

11. A system for multi-layer orchestration in a software defined network (SDN), the system comprising:

an orchestrator comprising at least one processor and memory, and for optimizing network resources within an SDN, the orchestrator being configured to receive orchestration related data for implementing a network service using the network resources within the SDN, determine configuration information for the network resources based on the orchestration related data and protocol layer capability of the network resources, and provide the configuration information to the network resources;

wherein the orchestrator being configured to determine the configuration information includes identifying the network resources having the protocol layer capability to provide network services.

12. The system of claim 11 wherein the orchestration related data is received from an operations module.

13. The system of claim 11 wherein the orchestration related data includes at least one of:

network service catalogue information; and

a network service graph.

14. The system of claim 11 wherein the orchestrator is further configured to analyze the orchestration related data and the protocol layer capability of the network resources and identify to which of the network resources to provide the configuration information.

15. The system of claim 14 wherein the orchestrator is configured to apply an algorithm to the orchestration related data and the protocol layer capability of the network resources to determine which of the network resources provide an optimized flow of network traffic.

16. The system of claim 11 wherein the protocol layer capability comprises an ability of a network resource to control network traffic using at least one criterion associated with a particular protocol layer.

17. The system of claim 11 wherein the network resources comprise at least one of a switch, a router, a layer 3 switch, a layer 3 router, a layer 4 router, a layer 7 application server, a layer 7 router, a controller, and another network element.

18. The system of claim 11 wherein the orchestrator is configured to automatically orchestrate connections between the network resources.

19. The system of claim 18 wherein the orchestrator is configured to automatically orchestrate a connection between a layer 7 router and at least one layer 4 router.

20. A non-transitory computer readable medium having stored thereon computer executable instructions embodied in a computer readable medium and when executed by a processor of a computer performs steps comprising:

at an orchestrator comprising a hardware processor and for optimizing network resources within a software defined network (SDN);

receiving orchestration related data for implementing a network service using the network resources within the SDN;

determining configuration information for the network resources based on the orchestration related data and protocol layer capability of the network resources, wherein determining the configuration information includes identifying the network resources having the protocol layer capability to provide network services; and

providing the configuration information to the network resources.
