\u2022 User-Network Interface (UNI): The UNI is a physical Ethernet port on the service provider side of the network along with a\u00a0predefined set of parameters to provide data, control and management traffic exchange with the end-customer CPE device. The customer CPE device can be a Layer 2 Ethernet switch, Layer 3 routing node or some of LTE nodes.<\/p>\n

\u2022 Network-to-Network Interface (NNI): \u00a0NNI is represented by the physical Ethernet port on the service provider access node that is used to interconnect two Ethernet MANs of two different service providers. We are also using E-NNI as a reference point for the interconnection of Layer 2 MAN service with Layer 3 service nodes\u2014the provider edge router (PE)<\/a>, a broadband network gateway (BNG)<\/a>, vertical handover (VHO)<\/a>, etc\u2014in the provider network.<\/p>\n
