The Network to Network interface (NNI) forms the transition between different networks and service providers. Since this interface causes problems in the transition between Next Generation Networks (NGN) with Carrier Ethernet, the Metro Ethernet Forum (MEF) has defined a new interface for network transitions with the Ethernet Network to Network Interface (ENNI). At the NNI level, E-NNI uses standards according to IEEE 802.1ad or Multi-Protocol Label Switching (MPLS).
