What is SWAN?

SWAN State Wide Area Network

Network - The term Network stands for a group of

telecom systems and computers connected to each otherby 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)


4/52

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.


5/52

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.


6/52

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 ofnetworks spread over a geographical area


7/52

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.

E-Governance need

Various E-Governance applications are being developed for efficientdelivery of service to citizens. For eg:

Transport-Registration of MotorVehicles, issuing driving licenses

etc. Health Care- Linking various Hospitals Tele-Medicine etc.

Education-Linking various educational Institutions, distancelearning etc.

Employment-Online Registration for unemployed,

computerization of day to day activities of employment exchangeetc.

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 nowbeen identified as an element of core infrastructure for supportinge- Governance initiatives. DIT, GOI has also embarked asignificant outlay for supporting this activity. Under NeGP SWANpolicy it is proposed to connect state capital (SHQ) with all the

Districts Head Quarter (DHQ) and subsequently all the DHQ to beconnected with Sub-division Head Quarter/Blocks (SDHQ/Block).


13/52

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 theDistricts Head Quarter (DHQ) and

subsequently all the DHQ to be connected

with Sub-division Head Quarter / Blocks

(SDHQ/Block).


14/52

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 outsourcingestablishment, operation and maintenance of the

Network.

Option II: Designated NIC as the prime implementation

agency for the SWAN for establishment, operation andmaintenance of the network as an integral part of

NICNET, with an appropriate end-to-end Service Level

Agreement (SLA).


15/52

Department of IT, GoI supports (cost/funding) to state Governmentw.r.t. different options.

DIT will support the entire cost of establishment, operation andmaintenance of the SWAN for a period of five years (except

recurring charges of Bandwidth) to state Govt / NIC on 100% grantbasis .

Terminal equipment at each Point of Presence (PoP) one PoP ateach 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).

NetworkMonitoring & Management

The Network monitoring & management software are an integral part of thenetwork performing the following tasks :

To give accurate report of Hardware and Software deployed on the network.

To give comprehensive report on the configuration of Hardware andSoftware change made in any part of the network.

To drill down to a particular network element to view the details of theresponse time, availability, reloads, protocols and interface status. Toidentify & 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 itscomponents/ links / Facilities and overall Network.

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

ForVertical connectivity only BSNL has network across the state.

Categories


46/52

Benefits ofMSWAN

Tangible Benefits

Financial Savings MSWAN would help inconsiderable time saving for the direct users resultingin an increase in the productivity of the employee. This

increase in productivity would result in financialsavings to the government

Time Management - Due to MSWAN the decisionmaking process, plan formulation and implementationwould be effective and it would also save the workhourof all government employees

Due to MSWAN there would also be savings inexpenditures like Telecom, Travelling, Fuel andStationery etc.
