Abstract

A method for performing an operation at a non-originating node of a connection includes receiving a request for the operation; determining information associated with the connection; and signaling, based on the information and the operation, an originating node to cause the originating node to perform call connection management on the connection. A non-originating node includes a plurality of ports with at least one connection thereon; and a controller communicatively coupled to the plurality of ports and operating a control plane, wherein, for an operation of call connection management on the at least one connection, the controller is configured to: determine information associated with the at least one connection on a link formed by a port; and signal, based on the information and the operation, an originating node of the at least one connection to perform the call connection management on the at least one connection.

First claim

What is claimed is:

1. A method for performing an operation at a non-originating node of a connection, comprising:
receiving a request for the operation;
determining information associated with the connection, wherein the determining is performed by searching, based on both a connection identifier and an originating node of the connection, managed objects stored at the non-originating node; and
signaling, based on the information and the operation, the originating node to cause the originating node to perform call connection management on the connection.

2. The method of claim 1 , wherein the operation comprises any one or more of regroom, manual switch to protect, revert, and configure.

3. The method of claim 1 , wherein the signaling is performed through a control plane comprising any of Automatically Switched Optical Network (ASON), Generalized Multi-Protocol Label Switching (GMPLS), and Optical Signaling and Routing Protocol (OSRP).

4. The method of claim 3 , wherein the control plane is configured such that the call connection management is performed by the originating node, and wherein the non-originating node performs the call connection management through the originating node.

5. The method of claim 3 , wherein the signaling utilizes control plane signaling messages with data included therein in Information Elements to trigger the operation to perform the call connection management.

6. The method of claim 5 , wherein the control plane signaling messages comprise notify messages or release messages.

7. The method of claim 1 , wherein the connection identifier comprises a Network Call Correlation Identification (NCCI).

8. The method of claim 1 , wherein the originating node performs the operation on the connection subsequent to receiving the signaling by the non-originating node; and the method further comprises:
receiving signaling from the originating node with one of a notification and a release based on the operation with a status included therein.

9. The method of claim 1 , wherein the connection comprises one of a Subnetwork Connection (SNC) or a Label Switched Path (LSP).

10. The method of claim 1 , wherein the request is received from a Software Defined Networking (SDN) controller.

11. The method of claim 1 , wherein the operation is a manual switch to protect to free up bandwidth on a link.

12. A non-originating node, comprising:
a plurality of ports with at least one connection thereon; and
a controller communicatively coupled to the plurality of ports and operating a control plane, wherein, for an operation of call connection management on the at least one connection, the controller is configured to:
determine information associated with the at least one connection on a link formed by a port, wherein the non-originating node is configured to search through managed objects, based on both a connection identifier and an originating node of the at least one connection, to determine information associated with the at least one connection; and
signal, based on the information and the operation, the originating node of the at least one connection to perform the call connection management on the at least one connection.

13. The non-originating node of claim 12 , wherein the operation comprises any one or more of regroom, manual switch to protect, revert, and configure.

14. The non-originating node of claim 12 , wherein the control plane comprises any of Automatically Switched Optical Network (ASON), Generalized Multi-Protocol Label Switching (GMPLS), and Optical Signaling and Routing Protocol (OSRP); and
wherein the control plane is configured such that the call connection management is performed by the originating node, and wherein the non-originating node causes performance of the call connection management through the originating node.

15. The non-originating node of claim 12 , wherein the non-originating node utilizes control plane signaling messages with data included therein in Information Elements to trigger the operation to perform the call connection management.

16. The non-originating node of claim 12 , wherein, to perform the operation in the call connection management, the non-originating node is configured to:
determine information associated with the connection;
signal, based on the information and the operation, the originating node to perform the call connection management on the connection; and
receive a status signal from the originating node.

17. The non-originating node of claim 12 , wherein the operation is a configure operation including any of changing a Tandem Connection Monitoring number of the connection, converting a Subnetwork Connection (SNC) to a Permanent SNC (PSNC) or mesh SNC, and editing any editable call connection parameters of the connection.

18. An originating node, comprising:
a plurality of ports with at least one connection thereon; and
a controller communicatively coupled to the plurality of ports and operating a control plane, wherein, for an operation of call connection management on the at least one connection, the controller is configured to:
receive a signaling message from a non-originating node on a port and perform the call connection management based thereon, wherein the non-originating node i) receives a request for the call connection management, ii) determines information associated with the at least one connection based on a search, based on both a connection identifier and the originating node of the at least one connection, managed objects stored at the non-originating node, and iii) signals the signaling message based thereon to the originating node; and
signal a status to the non-originating node.
