Details

The NKN is a hierarchical network divided into three basic layers – ultra-high speed CORE (multiples of 10 Gbit/s; Level 1), Distribution (Level 2), and Edge (speeds of 1 Gbit/s or higher; User Level). Depending on the type of connectivity required by the user organization, geographical presence, and the location of Point of Presence (PoP) of NKN, (belonging to Core and Distribution), connectivity would be provided to the institutes. NKN backbone will typically have 18 Core PoPs and around 25 Distribution PoPs across the country. The NKN backbone will be created by multiple bandwidth providers and the edges can be provided by any service provider. The network is designed to support Overlay Networks, Dedicated Networks, and Virtual Networks. Advanced applications in areas such as Health, Education, Science & Technology,
