What is SWAN?
SWAN – State Wide Area Network
Network - The term ‘Network’ stands for a group of telecom systems and computers connected to each other by some communication channel to share the resources.
Types of Network:-
1) Local Area Network (LAN)
2) Metropolitan Area Network (MAN)
3) Wide Area Network (WAN)
4
Local Area Network (LAN) LAN – It connects network devices over a relatively
short distance like in a single building or campus . LANs are typically owned, controlled and managed by a single person and organization.
5
Metropolitan Area Network (MAN)
MAN - A MAN is designed to extend over an entire city. It may be a single network, or it may be a means of connecting a number of LANs into a larger
network.
6
Wide Area Network (WAN)
WAN – A WAN provides long distance transmission of data, voice, image and video information over large geographical areas that may comprise a country, continent, or even the whole world.
Wide Area Network is a collection of networks spread over a geographical area
7
SWAN
State Wide Area Network (SWAN) – It is a WAN covering whole state, incorporating many networks for providing data, voice and video services throughout the state.

Requirement of SWAN
A government to be SMART (Simple, Methodological, Accountable, Responsive, Transparent) needs to have:
Efficient & reliable communication network
Improved information flow among various levels and offices
Reduced communication gaps
Improved quality and speedy decision making
Faster and better implementation of government schemes
10
E-Governance need
Various E-Governance applications are being developed for efficient delivery of service to citizens. For eg:
Transport-Registration of Motor Vehicles, issuing driving licenses etc.
Health Care- Linking various Hospitals Tele-Medicine etc.
Education-Linking various educational Institutions, distance learning etc.
Employment-Online Registration for unemployed, computerization of day to day activities of employment exchange etc.
Municipal- Bill deposition, Issue of Certificates - Birth / Death / Land records etc.

12
Different Agencies - DIT
Govt. of India, Department of Information Technology (DIT)
The Government of India has planned a national level initiative- National e-Governance Plan, (NeGP) for increased transparency, efficiency and effectiveness for delivery of citizen services.
An important component of the NeGP is SWAN; which has now
been identified as an element of core infrastructure for supporting e- Governance initiatives. DIT, GOI has also embarked a significant outlay for supporting this activity. Under NeGP SWAN policy it is proposed to connect state capital (SHQ) with all the Districts Head Quarter (DHQ) and subsequently all the DHQ to be connected with Sub-division Head Quarter/Blocks (SDHQ/Block).
13
Different Agencies - DIT
SWAN is one of the Mission Mode project Total NeGP outlay for SWAN – Rs 3000 Cr To connect state capital (SHQ) with all the
Districts Head Quarter (DHQ) and subsequently all the DHQ to be connected with Sub-division Head Quarter / Blocks (SDHQ/Block).
14
Implementation Plan
State would need to establish the SWAN using either of the two options provided by DIT, GOI:
Option I: State to identify a suitable PPP model (BOO, BOOT etc.), select an appropriate agency through a suitable competitive process for outsourcing establishment, operation and maintenance of the Network.
Option II: Designated NIC as the prime implementation agency for the SWAN for establishment, operation and maintenance of the network as an integral part of NICNET, with an appropriate end-to-end Service Level Agreement (SLA).
15
Department of IT, GoI supports (cost/funding) to state Government w.r.t. different options.
DIT will support the entire cost of establishment, operation and maintenance of the SWAN for a period of five years (except recurring charges of Bandwidth) to state Govt / NIC on 100% grant basis .
Terminal equipment at each Point of Presence (PoP) one PoP at each location (without horizontal connectivity) i.e. SHQ/DHQs/SDHQs/BHQs covered by the SWAN.
Cost of consultancy (only for option I)
Cost of Third party monitoring (option I) / Cost of Third party auditors (option II).
Implementation Plan

To give accurate report of Hardware and Software deployed on the network.
To give comprehensive report on the configuration of Hardware and Software change made in any part of the network.
To drill down to a particular network element to view the details of the response time, availability, reloads, protocols and interface status. To identify & analyze failures of any link / element on the network
To isolate network error condition and suggest probable cause.
To print traffic analysis of peak / lean hours/days/months etc.
To print down time / Up time w.r.t various Network elements and its components/ links / Facilities and overall Network.
45
Connectivity Analysis
Two categories of connectivities are required for MSWAN:
Vertical : i) SHQ to 7 DHQs ii) DHQ to SDHQs / BHQs
Horizontal : i) Government offices in Shillong to SHQ ii) District offices with DHQ and
iii) Sub divisional offices to SDHQ
For Vertical connectivity only BSNL has network across the state.
Categories
46
Connectivity AnalysisBSNL Option
Network exists throughout the Meghalaya state
Leased lines available from SHQ to 7 districts, 8 Subdivisions and 23 Blocks
No leased line facility at 14 Blocks, (viz. Baghmara, Betasing, Chokpot, Gasupara, Gambegre, Shella, Lasiken, Mawjrong, Mawkynrew, Ranikore, Rongra, Saipung, Samanda and Zigzag) as indicated during meeting with BSNL officials.
In 2 Blocks (Chokpot and Jirang – Patharkhmah)E1 link will be available after December 2006
47
Connectivity Analysis
Solution
– Vertical Connectivity • Leased Links from BSNL for Vertical connectivity wherever
available
• VSAT link for Blocks wherever BSNL connectivity in not available
– Horizontal Connectivity
• Hybrid solution including Leased Lines, RF, OFC etc depending on the location & best suited technology vis - a- vis cost.
48
Outsourcing Model
Modified BOOT Model
Services required as required by the State Govt. are specified
Govt. releases guaranteed payments on quarterly basis against the services prescribed in SLA (Service Level Agreement)
Vendor to take care of the availability of the spares to maintain guaranteed uptime
For monitoring of network, separate agency need to be involved (if required) and paid accordingly
49
Bandwidth Requirement
Path Initial Future (Anytime)
SHQ to DHQ 2 Mbps 8 Mbps or more
DHQ to SDHQ / BHQ 2 Mbps 4 Mbps or more
SHQ to Remote BHQs 512 Kbps VSAT BW shared
2 Mbps Shared
Mobile Van 512 Kbps 2 Mbps
Internet 4 Mbps 8 Mbps or more
