and 6 Union Territories. Common Service Centers (CSC) schemes would serve as the end delivery points. The Department of Information Technology, Government of India, is the nodal department for each SWAN implementation. The scheme was a “centralized initiative with decentralized implementation”.CSC connectivity options official page

Objectives

* The SWAN aims to create a dedicated closed user group (CUG) network of minimum speed of 2 Mbit/s by connecting around 7500

Architecture

The SWAN is required to be an open standards based, scalable, high capacity network to carry voice, data and video traffic between the designated State Government offices at the State, district and sub division / block levels. The connectivity to the end-user is based on either one or more of the standard technologies such as leased circuits, VSAT, radio frequency dial-up circuits or using appropriate

ports for the individual offices. The network would have single point gateways of adequate capacity connected to the Internet. The entire SWAN architecture is logically divided into two components.


Vertical component

The vertical component of SWAN is implemented using multi-tier architecture (typically, three-tier) with the State/UT Headquarters (SHQ ) connected to the each District Headquarters (DHQ) which in turn gets connected to the each Block Headquarters (BHQ).NeGP overview

Horizontal component

The Horizontal component of SWAN is composed of horizontal offices spread across the State. All vertical PoPs of SWAN will have various Horizontal connectivity. In horizontal component, the government departments at each tier are connected to the respective PoPs.


Implementation

There are two options to the State Governments for State Wide Area Network establishment. The first option is the

Department of IT support covers the entire cost of establishment, operation and maintenance of the SWAN for a period of five years on 100% grant basis. A majority of the States / UTs have opted for the PPP model.
