• 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.
