multi-gigabit pan-India network for providing a unified high speed
network backbone for all knowledge related institutions in the
country 9 th April 2009: Honble President of India, Smt. Pratibha
Devisingh Patil inaugurated the NKN Project. On this day the status
was: 16 PoP 26 Backbone Links 57 Edge Links National Informatics
Centre (NIC) working as the Project Execution Agency GoI approved a
budget of INR 5990 crores for NKN in March, 2010 An idea mooted
from the Office of Principal Scientific Advisor, GoI. & NKC
Will connect R& D, educational, health, e-gov and agricultural
institutes 550+ Institutes in Phase-I & 1500+ institutes by the
end of final phase Introduction Key Highlights of NKN 5th March,

National Knowledge NetworkPage 6 NKN provides a common platform
to the scientists, researchers, doctors, scholars and students to
work together for advancing human development. NKN shall be a
knowledge base for revolutionizing the education system of country
The architecture of NKN has been designed for reliability,
availability & scalability The network consists of an
ultra-high speed core, starting with multiple 2.5/10 G and
progressively moving towards 40/100 Gigabits per Second (Gbps) The
core is complimented with a distribution layer covering all
districts at appropriate speeds The participating institutions at
the edge would seamlessly connect to NKN at Gigabit per second
speed. Key Highlights

Slide 12
National Knowledge NetworkPage 12 The backbone of the network
starts from 2.5 Gbps and progressively moves onto 10 Gbps
connectivity between 7 Supercore (fully meshed) locations across
India. The network is further spread out through Core locations
with multiple of 2.5/10 Gbps partially meshed connectivity with
Supercore locations. The network architecture and governance
structure allows users with options to connect to the distribution
layer as well. For special interest groups, NKN enables Virtual
Private Networks NKN provides international connectivity to its
users for global collaborative research. Presently, NKN is
connected to: Trans Eurasia Information Network (TEIN3) Similar
connectivity to GLORIAD network is in the pipeline Technical

Slide 19
National Knowledge NetworkPage 19 What Is a Virtual Private
Network? VPN is a set of sites or groups which are allowed to
communicate with each other VPN is defined by a set of
administrative policies Policies established by VPN customers
Policies could be implemented completely by VPN service providers
Flexible inter-site connectivity Ranging from complete to partial
mesh
