e- Governance
-Technology Driven governance
- Application of ICT (Information and
Communication Technology) for delivering
governance.
Need of the hour is e-governance
Governance
• Delivering government services
• Exchanging information / communication / transactions.
• Integration of systems & services between G2C, G2G,
G2B.
• Back Office processes & interactions.

Governance
Services through ICT
• e education
• e medicine
• e governance
• Entertainment ( IPTV + Cable TV)
• Disaster services
• Local broadcasting
• Security and Surveillance
• Video conferencing
E-governance
• has no distinct boundaries
• cuts down unwanted interference of too
many layers
• can reach the desired individual
directory
• can achieve corruption free
government.
How do we achieve this?
The e-governance applications with high
video/animation content can be delivered
only if we have high speed/bandwidth
connectivity which can be achieved
through Broadband with adequate
bandwidth.
T To meet the challenges of connectivity the
Government of India has approved the
scheme for creation of the National Optical
Fibre Network (NOFN) to provide
Broadband connectivity to 2.5 lakh village
Panchayats (councils).

Table 1 summaries various applications in Indian scenario
and bandwidth required to support such applications. From
this, It is observed that tentative bandwidth requirements to
run various applications ranges from 64 Kbps to 8 Mbps.

Broadband Speed • 256Kbps - This speed is appropriate for viewing most
websites, taking about 3 secs for the website to load. This
speed is about 5 times faster than the speed given with a
56Kbps dial-up Internet connection.
• 512Kbps - This is the most common speed used in homes
and small businesses. It takes 1.6 secs for a website to
load and about 1.5 mins to download a 5min music file at
maximum speed. This speed is suitable for video and
music streaming and for viewing most websites.
• 1Mbps - This speed is also commonly used amongst
homes and small businesses. It is appropriate for website
viewing, streaming and online gaming. It takes 0.8 secs to
load a web page and about 40 secs to download a 5 min
music file at maximum speed.
www.cdot.in Copyright © 2012 C-DOT. All Rights Reserved.
• 2Mbps - This and faster speeds are more suitable
for people who play a lot of demanding online
games. It is also suitable for people who share one
Internet connection between many PC-s. It takes
0.4 seconds to load a website and about 20
seconds to download a 5 minute music file at
maximum speed.
• 24Mbps - Ultra fast broadband offered These high
speed services are particularly good for watching
real-time DVD quality film.

NOFN (National optical fibre network)
Govt of India has approved the project of NOFN
to connect all 2.5 Lac Panchayats with
minimum 100 Mbps speed for provision of
various E‐Gov applications, various services
and also support Telecom operators to roll
out services in rural areas thereby enabling
access of best technologies to the rural
population. An amount of Rs 25,000 crores
have already been sanctioned by the Govt for
this project which will be funded through
USOF (Universal service obligation fund).

NOFN Project implementation Institutions/Agencies are associated with NOFN
Project implementation are DOT, BSNL, RailTel,
PGCIL, C-DOT, TCIL and NIC which are working
with BBNL on the NOFN Project. The funding of the
project is from USOF.

Expected Features of NOFN
NOFN shall be built using indigenous hardware
(e.g GPON (Gigabit Passive Optical Network)
will be used for NOFN Project) & software
technology and products to ensure national
security (e.g. NMS (Network Management
System), .
NOFN shall have at least 1 Gbps capacity at the
panchayat level.
NOFN shall provide at least 100 mbps at the
panchayat level in exchange of right of way by
states, with backhaul up to district level.
www.cdot.in Copyright © 2012 C-DOT. All Rights Reserved.
Expected Features of NOFN
NOFN shall be a 365x24 reliable, robust, scalable and
available IP capable network to ensure continuous
availability of services.
NOFN Shall Lease Dark Fiber / Lambda (Launch Alien
Lambda) / Bandwidth On Long term Lease (IRU)
from BSNL, RailTel, PowerGrid and others as and
when necessary on the existing and available fiber
NOFN shall have a national network operating center
(NOC) using NMS with full visibility of the network, all
activities observable in real time, and controllable
from a central location at element level.

Progress of NOFN GPON (Gigabit Passive Optical Network) will be
used for NOFN Project. GPON is an open
standard technology. C-DOT has developed this
technology and the approval has been obtained
for the same from TEC.

Advantages of GPON
The GPON (Gigabit Passive Optical Network)
standard differs from other PON standards in
that it achieves higher bandwidth and higher
efficiency using larger, variable-length
packets.
A Passive Optical Network (PON) is a network
architecture that brings fiber cabling and
signals to the home using a point-to-
multipoint scheme that enables a single
optical fiber to serve multiple premises.
www.cdot.in Copyright © 2012 C-DOT. All Rights Reserved.
Advantages of GPON
Encryption maintains data security in this
shared environment. The architecture uses
passive (unpowered) optical splitters,
reducing the cost of equipment compared to
point-to-point architectures.
C-DOT has done the Transfer of Technology for
GPON to manufacturers which includes both
CPSUs and private, to meet NOFN timely
supply of equipments.

(D-RAX) Once the Broadband access in education is
available one can:
Enable data systems and platforms to support
teaching and learning.
Help schools and districts as textbooks are
replaced by digital content in coming years.
Increase data availability and the ability to provide
consistent electronic education records, across
schools and across the states.
