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.
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.
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 M anagemfrom ent SW 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-tomultipoint scheme that enables a single optical fiber to serve multiple premises.
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.
