                 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)

           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.

          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

         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


   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

                 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
     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
     Municipal- Bill deposition, Issue of Certificates - Birth / Death /
      Land records etc.

             Different Agencies

   Department of Information Technology (DIT),
   State’s Information Technology Department
   Consultants
   Implementing Agency
   NicNET
   Third Party Monitoring Agency

             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).

          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

              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

   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).
                  Implementation Plan
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).

                   TCIL’s Role
Role of TCIL w.r.t. different options are as follows:
Option I:
 Consultant

 Implementing Agency: All the states, except where
  TCIL is the consultant.
 Third party Monitoring: All the states, except where
  TCIL will implement

Option II:
 Auditors

 Third party Monitoring

     redundancy, whenever required by GoM, to the extent
     that each DHQ may be connected to the adjacent
     DHQ and each DHQ is connected to SHQ

                Network Monitoring & Management
    The Network monitoring & management software are an integral part of the
    network 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 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.

               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.

                Connectivity Analysis
BSNL Option

   Network exists throughout the Meghalaya state

   Leased lines available from SHQ to 7 districts, 8 Subdivisions and 23

   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

              Connectivity Analysis
–   Vertical Connectivity
•   Leased Links from BSNL for Vertical connectivity wherever
•   VSAT link for Blocks wherever BSNL connectivity in not
–   Horizontal Connectivity
•   Hybrid solution including Leased Lines, RF, OFC etc
    depending on the location & best suited technology vis - a-
    vis cost.

               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

   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

             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       2 Mbps Shared
                        BW shared

Mobile Van             512 Kbps              2 Mbps

Internet                4 Mbps       8 Mbps or more

         Benefits of MSWAN
Intangible Benefits

   Productivity Benefits
   Managerial Benefits

   High IT Industrial Growth
   Image building of the State

               Benefits of MSWAN
Tangible Benefits
   Financial Savings – MSWAN would help in
    considerable time saving for the direct users resulting
