Virtual UNI (vUNI) is the component consisting of a collection of service attributes in the vUNI Provider's CEN. The vUNI is paired with a remote UNI in a CEN Operator's network. The main function of the vUNI is to map frames between a set of one or more OVCs present in the vUNI Provider domain and a single UNI Tunnel Access (UTA).
