The following protection schemes are supported around SNCP in NMS:
Fully Protected SNCP circuit: Single work path and single protect path are from source node to destination node. The paths can be represented either in node-disjoint or link-disjoint manner as follows:
Partially Protected SNCP circuit: Single work path and one or more protect path(s) are from end to end. It can be protecting a segment of work path or multiple segments as follows:
DIAMOND Protected Circuit: The three end to end paths includes work, protect and backup paths, which are node-disjoint from source node to destination node as follows. For more details on diamond circuit, refer the section "Creating Circuits using Diamond Services" mentioned in the User Guide document:
Work Segment (Work segment protection along with fully protected SNCP circuit): In addition to the fully protected SNCP circuit, you can protect the part of work segment for more resiliency. This work segment cannot start or terminate on the end nodes.
NOTE: Additional segment protection along the protect path is not supported.
