NNI stands for Native Network Internet; it’s a network topology, that is primarily applied by telecom service providers to facilitate interconnection of their networks. The NNI enables the networks of various providers to be interconnected while at the same time keeping the network of the provider and the outside world network different. The major objective of the NNI is to define the interfaces for connecting external and internal networks of service providers. This helps them to undertake end-to-end service provision across the networks owned by different operators. Some key benefits of the NNI architecture include: Some key benefits of the NNI architecture include: - Promoting favorable operability through the provision of defined interfaces for traffic exchange between different providers - … it is imperative to separate the internal network of the provider from the outside world to avoid compromise of the data. - Enabling the providers to meet fully integrated and end-to-end solutions across different networks - The Enhancement of hand-offs and the ability to roam while using mobile networks - The enforcement of policies at policy enforcement points is vital for supporting quality of service capabilities between operators - The third benefit is to facilitate the rapid deployment of new services due to the ability to on-board new partners more quickly. The NNI architecture still maintains flexibility to support new technologies that may emerge in the future. Some of the emerging trends include the increased capabilities aimed at enabling and optimizing the handover between service providers, enhanced security solutions, as well as utilizing network slicing for various services on the same infrastructure.
