Systems and methods for utilizing protection paths
The present disclosure includes a method of utilizing protect paths, the method includes receiving a first message regarding a first failure in a first working path and receiving a second message regarding a second failure in a second working path. The method also includes matching a pattern comprising received messages regarding working path failures to a stored group comprising a plurality of connection identifications (IDs) that share identical protection paths and share a resource trail, the group being associated with a group identification (ID). The method additionally includes transmitting a third message to provision the identical protect paths for the group associated with the group identification. The present disclosure may also include associated systems and apparatus. The present disclosure may further include methods, systems, and apparatuses associated with provisioning groups utilized in methods of the present disclosure.
1. A method of utilizing protection paths of network, the method comprising:
determining, from among a plurality of connection identifications (IDs), connection IDs that share identical protection paths and share a resource trail of a network, each of the plurality of the connection IDs is associated with a working path of the network;
assigning the determined plurality of connection IDs to a group with an associated group identification (ID);
storing the group ID and the determined plurality of connection IDs in a first node of the network;
receiving, at the first node, a first message regarding a first failure in a first working path of the network;
receiving, at the first node, a second message regarding a second failure in a second working path of the network;
determining, from the stored group ID and the determined plurality of connection IDs, a group ID associated with both the connection ID of the first working path and the connection ID of the second working path; and
transmitting a third message, that includes the group ID associated with both the connection ID of the first working path and the connection ID of the second working path, that indicates that the protection paths associated with the first working path and the second working path are to be provisioned.
2. The method of claim 1 , wherein the group ID and the identical protection paths are stored in a database at the first node.
3. The method of claim 1 , wherein the group ID associated with both the connection ID of the first working path and the connection ID of the second working path is transmitted to all nodes of the identical protection paths.
4. The method of claim 1 , wherein the first node is a head node of the identical protection paths.
5. The method of claim 1 , wherein the determining, from among a plurality of connection IDs, connection IDs that share identical protection paths and share a resource trail further comprises transmitting a message to traverse working paths of the plurality of connection IDs to facilitate analysis of overlap of working path resources.
6. The method of claim 5 , wherein the determining, from among a plurality of connection IDs, connection IDs that share identical protection paths and share a resource trail further comprises analyzing initially provisioned protection paths.
7. The method of claim 1 , further comprising in response to receiving the first message, initiating a timer to wait for additional messages.
8. The method of claim 7 , wherein the determining, from the stored group ID and the determined plurality of connection IDs, a group ID associated with both the connection ID of the first working path and the connection ID of the second working path is not made until after expiration of the timer.
9. The method of claim 7 , wherein the third message is not transmitted until after expiration of the timer.
10. The method of claim 7 , wherein the timer counts for between 0 and 200 milliseconds.
11. The method of claim 1 , further comprising:
receiving a fourth message regarding a third failure in a third working path; determining that the third working path does not share a protection path with the identical protection paths; and
transmitting a fifth message to provision the protection path.
