    abstract =  {A multi-layer approach to the task of Operation, Administration and Maintenance (OAM) of Service Function Chains (SFCs) in networks is presented. Based on the requirements towards active OAM for SFC, a multi-layer model is introduced. A mechanism to detect and localize defects using the multi-layer model is also described.},
