In this video, we look at optical traffic survivability through GMPLS Protection and Restoration Combined (PRC) and explain the PRC mechanism implemented at L1, describe the Multi-Regional Network model (MRN) and describe how to configure the restoration through NFM-T. We will configure a GMPLS-L1-restorable PRC service, which provides a combination of fast protection with robust restoration.
This video is based on content from the Nokia Optical Network Certification (ONC) Program, an end-to-end learning program supporting Nokia 1830 PSS, VWM and NFM-T based networks.
