1 November 2012 NKN Overview 2 of 31

Experience life with 1000000000 bps

9th April 2009


NKN is a state-of-the-art multi-gigabit pan-India network for providing a unified high speed

network backbone for all knowledge related institutions in the country

► 9th April 2009: Hon’ble President of India, Smt. Pratibha Devisingh Patil inaugurated the NKN Project. ► 16 PoP ► 26 Backbone Links ► 57 Edge Links Will connect Research

& Development,

educational, health,

and agricultural

institutes

Allocation of `100

Crore for the

implementation of Pilot

phase of NKN

An idea from the Office

of Principal Scientific

Advisor GoI, & NKC

National Informatics

Centre (NIC)

designated as the

Project Execution

Agency

GoI approved a budget

of Rs 5990 Crores for

NKN in March, 2010

Introduction Key Highlights of NKN

► 5th March, 2011: Hon’ble Minister Comm & IT, Shri Kapil Sibal and Hon’ble Minister of State for Comm & IT, Shri Sachin Pilot launched the Logo and Website of NKN ► 31 PoP ► 76 Backbone Links ► 216 Edge Links

1500+ institutes to be

connected; connectivity

to 885 institutes has

already been provided


► Need a single infrastructure that supports multitude of

applications in a secure manner

► Provide a scalable mechanism

► Load balance traffic to utilize network bandwidth

efficiently

► Allow core routers/networking devices to switch packets

based on some simplified header

► QoS aware network

► Scalable/ Adaptable/ Available (24X7X365)

Enable, Encourage, Empower, Enrich

Virtual Classrooms • Virtual classroom is a replica of the local class room

teaching where in the students at remote locations will

get the same feel and experience as if they are in the

same classroom .

• Teacher and students have full interactivity with each

other

• Teacher will be able to use all conventional teaching tools

and continue to teach the way he does.

• Students can ask questions and interact with the teacher

as if he is in the local classroom

What’s planned? -MPLS L3 VPN

► VPN service is enabled on PEs (VRFs are created and applied to VPN site interface)

► VPN site’s IITm connects to a VRF enabled interface on a PE1

► VPN site routing by IITm is distributed to MP-iBGP on PE1

► PE1 allocates VPN label for each prefix, sets itself as a next hop and relays VPN site routes to PE4

► PE4 distributes IITm’s routes to IITb (Similar happens from IITb’s side)

NKN Setup at Edge location


High Availability through Design


OPERATIONAL

► Complexity in existing Network

► Multiple Networks in Institute

► No single point of contact in many cases

► Reluctance to Change

MIND SET

►Why Should I change My Setup

►Will the change that we make are

permanent.

►Multiple Scheme

TECHNOLOGY

► IP Numbering Schema,

► Multi-Homing

► Hardware compatibility

► IPv6 addresses from APNIC

Manageable for

short time….

► Edge links : 1500

NKN: On conclusion of final phase


National Knowledge Network Model Projects

► Model Projects: approved by MPEC (Model Projects Evaluation Committee)

► The virtual medical classroom: an emerging tool for teaching Medicine and science.

(AIIMS)

► The main objective behind the project is to help the students from other medical colleges to have similar

standard of teaching as available to students studying at AIIMS.

► Network Enabled Medical diagnosis and Education in Skeletal Imaging using X-Rays.

► Providing suitable tools and channels for huge data transmission of 2D X-Ray and 3D anatomical data

► Collected data to be used by Experts (Doctors) for remote Diagnosis

► Creation of a Public repository for education purposes.

► Indian Integration with Global Imaging System via McGill Linkage, NBRC, Manesar

► To develop a national imaging networking model between NBRC / its linked institutions and MNI/its

linked institutions for using the Canadian and Global Brain facilities.

► Computational imaging analysis and telemedicine with special references to epilepsy, dementia and

stroke which are the neurological dysfunction with maximal morbidity in India.

► Network enabled online Casting Simulation System (e-Foundry), IIT, Bombay

► It is developed for use by technical institutes and local SME foundries.

► Engineering students will be able to carry out virtual casting experiments and study the effect of various

design parameters on casting solidification and related defects.
