PLR: Point of Local Repair. It is the head node of the protection LSP, that is, the location where the fault occurs. When protection occurs, the protection label is pressed at this point, and the normal label is encapsulated in it.

MP: Merge Point. It is the tail node of the protection LSP. When the protection occurs, the protection label is displayed at this point, and the protection label is forwarded normally according to the original label.
