# Proposers - Lluis Gifre (CTTC) - Ricard Vilalta (CTTC) - Raul Muñoz (CTTC) # Description Implement "A YANG Data Model for Network Topologies" (IETF RFC8345 [1]) in NBI component to expose the network topology. Also considering to extend it to "YANG Data Model for Traffic Engineering (TE) Topologies" (IETF RFC8795 [2]) in NBI component. # Demo or definition of done An RFC8345-compliant endpoint should be exposed in the NBI component. Also an RFC8795-compliant endpoint is being considered. # Acknowledgements This work is funded by the European Commission through the HORIZON-JU-SNS-2022 ACROSS project with Grant Agreement number 101097122. # References 1.
