Network to Network Interface

from Wikipedia, the free encyclopedia

A Network to Network Interface ( NNI ), also known as Network Node Interface, is an interface between networks (network nodes) in communication technology . This can be the interface between public networks (Public NNI), but also between public and private networks.

NNI in telecommunications

In telecommunications, an NNI interconnection is a coupling of two telecommunications networks . According to the OSI model , the connection is on the 2nd layer.

Since there is no telecommunications provider that can reach all destinations through its own network, providers join forces and couple their networks in order to achieve greater network coverage or to connect more cost-effective locations that are not in their own network.
