2012 Jan

Product Portfolio: Carrier Ethernet | Standard Type: Superseded Standards

Summary:

The Metro Ethernet Network Architecture Framework specifies a reference point that is the in- terface between two Metro Ethernet Networks (MENs), where each Operator MEN is under the control of a distinct administrative authority. This reference point is termed the External Network Network Interface or ENNI.


The Metro Ethernet Network Architecture Framework specifies a reference point that is the interface between two Metro Ethernet Networks (MENs), where each Operator MEN is under the control of a distinct administrative authority. This reference point is termed the External Network Network Interface or ENNI. The ENNI is intended to support the extension of Ethernet services across multiple Operator MENs. This Technical Specification specifies: The requirements at the ENNI reference point as well as the interface functionali- ty in sufficient detail to ensure interoperability between two Operator MENs in- cluding Link OAM. The connectivity attributes UNI to UNI, UNI to ENNI, and ENNI to ENNI such that multiple Operator MENs can be interconnected and the Ethernet services and attributes in MEF 6.1 and MEF 10.2 can be realized.
