MEF 28 is a specification document developed by the Technical Committee of the MEF that defines the External Network Network Interface (ENNI) support for UNI Tunnel Access and Virtual UNI.
Abstract:
"The External Network Network Interface (ENNI) is a reference point that describes the interface between two Metro Ethernet Networks (MENs) [Editor: Carrier Ethernet Networks (CENs)] and is intended to support the transparent extension of Ethernet services across multiple Network Operator MENs [Editor: CENs], where each Network Operator MEN [Editor: CEN] is under the control of a distinct administrative authority. This Technical Specification extends the ENNI by defining the UNI Tunnel Access (UTA) which associates a Virtual UNI (VUNI), a remote UNI, and at least one supporting OVC."
