State Wide Area Network (SWAN)

  1. 1. State Wide Area Network (SWAN) - A Case study of Meghalaya SWAN (MSWAN) BY Amit Soni AM(TC) S&TC Division 8 th November 2006
  2. 2. Agenda <ul><li>What is SWAN ? </li></ul><ul><li>Requirement Of SWAN </li></ul><ul><li>Different Agencies in SWAN </li></ul><ul><li>TCIL Role </li></ul><ul><li>Case Study of Meghalaya SWAN </li></ul>
  3. 3. What is SWAN? <ul><li>SWAN – State Wide Area Network </li></ul><ul><li>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. </li></ul><ul><li>Types of Network:- </li></ul><ul><li>1) Local Area Network (LAN) </li></ul><ul><li>2) Metropolitan Area Network (MAN) </li></ul><ul><li>3) Wide Area Network (WAN) </li></ul>
  4. 4. Local Area Network (LAN) <ul><li>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. </li></ul>
  5. 5. Metropolitan Area Network (MAN) <ul><li>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. </li></ul>
  6. 6. Wide Area Network (WAN) <ul><li>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. </li></ul><ul><li>Wide Area Network is a collection of networks spread over a geographical area </li></ul>
  7. 7. SWAN <ul><li>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. </li></ul>
  8. 8. SWAN Subdivision / Block HQs State capital-SHQ Horizontal Offices 1 N District HQs 1 N Horizontal Offices Horizontal Offices
  9. 9. Requirement of SWAN <ul><li>A government to be SMART (Simple, Methodological, </li></ul><ul><li>Accountable, Responsive, Transparent) needs to have: </li></ul><ul><li>Efficient & reliable communication network </li></ul><ul><li>Improved information flow among various levels and offices </li></ul><ul><li>Reduced communication gaps </li></ul><ul><li>Improved quality and speedy decision making </li></ul><ul><li>Faster and better implementation of government schemes </li></ul>
  10. 10. E-Governance need <ul><li>Various E-Governance applications are being developed for efficient delivery of service to citizens. For eg: </li></ul><ul><ul><li>Transport-Registration of Motor Vehicles, issuing driving licenses etc. </li></ul></ul><ul><ul><li>Health Care- Linking various Hospitals Tele-Medicine etc. </li></ul></ul><ul><ul><li>Education-Linking various educational Institutions, distance learning etc. </li></ul></ul><ul><ul><li>Employment-Online Registration for unemployed, computerization of day to day activities of employment exchange etc. </li></ul></ul><ul><ul><li>Municipal- Bill deposition, Issue of Certificates - Birth / Death / Land records etc. </li></ul></ul>
  11. 11. Different Agencies <ul><li>Department of Information Technology (DIT), GoI </li></ul><ul><li>State’s Information Technology Department </li></ul><ul><li>Consultants </li></ul><ul><li>Implementing Agency </li></ul><ul><li>NicNET </li></ul><ul><li>Third Party Monitoring Agency </li></ul>
  12. 12. Different Agencies - DIT <ul><li>Govt. of India, Department of Information Technology (DIT) </li></ul><ul><li>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. </li></ul><ul><li>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). </li></ul>
  13. 13. Different Agencies - DIT <ul><li>SWAN is one of the Mission Mode project </li></ul><ul><li>Total NeGP outlay for SWAN – Rs 3000 Cr </li></ul><ul><li>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). </li></ul>
  14. 14. Implementation Plan <ul><li>State would need to establish the SWAN using either of the two options provided by DIT, GOI: </li></ul><ul><li>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. </li></ul><ul><li>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). </li></ul>
  15. 15. <ul><li>Department of IT, GoI supports (cost/funding) to state Government w.r.t. different options. </li></ul><ul><li>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 . </li></ul><ul><li>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. </li></ul><ul><li>Cost of consultancy (only for option I) </li></ul><ul><li>Cost of Third party monitoring (option I) / Cost of Third party auditors (option II). </li></ul>Implementation Plan
