Abstract
Methods and nodes are disclosed for OAM configuring one or more tandem connection monitoring layers through GMPLS signaling during GMPLS sub-network connection (SNC) establishment. Additionally, methods and nodes are disclosed for OAM configuring one or more tandem connection monitoring layers through GMPLS signaling after GMPLS sub-network connection establishment, that is, for existing connections.
