Connected Sites Under Initial Phase of NKN


► NKN will connect Educational Institutes, R&D institutions,Health service facilities, Agricultural institutions and Libraries ofthe country

► In March 2010, Government of India allocated a budget of INR5990 Crore for the Implementation of NKN

► Implementation plan was finalized by TAC under the guidanceof HLC

► National Informatics Centre (NIC) was appointed as the ProjectExecution Agency (PEA)

► On Conclusion of the final Phase NKN would have connected1500+ institutions

Introduction


► Need a single infrastructure that supports multitude ofapplications in a secure manner

► Provide a scalable solution► Provide low hop network► Allow core routers/networking devices to switch packets based

on some simplified header► Keep up to date with the technology► Available (24X7X365)

Need of the Hour


Key Highlights

► The architecture of NKN has been designed for reliability,availability & scalability

► The network consists of an ultra-high speed core, starting withmultiple 2.5/10 G and progressively moving towards 40/100Gigabits per Second (Gbps)

► The core is complimented with a distribution layer covering alldistricts at appropriate speeds

► The participating institutions at the edge would seamlesslyconnect to NKN at Gigabit per second speed

► At the conclusion of the final phase, NKN shall have presence in more than 500 districts of India with connectivity to major research and education institutions

► Points of Presence (PoP) : 31► Backbone Links : 89► Edge links : 1500

NKN: On Conclusion of Final Phase


Technical Overview

► The backbone of the network starts from 2.5 Gbps andprogressively moves onto 10 Gbps connectivity between 7Supercore (fully meshed) locations across India.

► The network is further spread out through Core locations withmultiple of 2.5/10 Gbps partially meshed connectivity withSupercore locations.

► The network architecture and governance structure allowsusers with options to connect to the distribution layer as well.

► For special interest groups, NKN enables Virtual PrivateNetworks

► NKN provides international connectivity to its users for globalcollaborative research. Presently, NKN is connected to:► Trans Eurasia Information Network (TEIN3)► Similar connectivity to few other research networks is in the pipeline

What Is a Virtual Private Network?

► VPN is a set of sites or groups which are allowed tocommunicate 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

Using Route-Reflector for Scaling

► 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)

Layer 2 VPNs

► Similar to L3VPN► Designate a label for the circuit► Exchange that label information with the egress PE► Encapsulate the incoming traffic (Layer 2 frames)► Apply label (learned through the exchange)► Forward the MPLS packet (l2 encapsulated to destination on an

LSP)► At the egress

(Router/ switch/ ups/ Racks from NLD)► Air- Conditioned Environment► UPS (5 KVA & 10 KVA Based on router supplied)► 24X7 access to NKN personnel or persons authorized by NKN► Seating place for one NKN appointed person► Safety of the equipments supplied under NKN► Cabling with in the user location for connecting to the NKN

router► Right of Way with in the User Campus for cabling to be done by

the long distance providers► Nodal Officer appointed will be the single point of interface for

NKN


Immediate Steps for Integration

► Migration plan ( short term)► start the discussions with the NKN team for suitable changes at

both the ends► Procurement of hardware where ever necessary through

existing empanelment► Workshop only for specific working group to formulate the

migration plan
