MEF 28 External Network Network Interface (ENNI) Support for UNI Tunnel Access and Virtual UNI

2010 Oct

Product Portfolio: Carrier Ethernet | Standard Type: Superseded Standards

Summary:

The External Network Network Interface (ENNI) is a reference point that describes the interface between two Metro Ethernet Networks (MENs) and is intended to support the transparent extension of Ethernet services across multiple Network Operator MENs, where each Network Operator MEN 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.

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. This Technical Specification specifies: The requirements for the UNI Tunnel Access (UTA) in sufficient detail to ensure interoperability between MENs. The service attributes necessary to realize UTA. The Virtual UNI (VUNI), remote UNI constraints, and related service attributes.
