Architecture

PAWAN is a three tier IP based Network (IPV6 ready) to provide connectivity among Punjab Government offices at State Head Quarter (SNC), District Head Quarter (DNC), Sub-Division (SDNC) & Block Head Quarters (BNC) with the objective of making information easily accessible across the various Departments and to the people across the State. Total 118 PoPs (Points of Presence) have been created across State. 

 

PAWAN Network Operating Centre (NOC) is at State Head Quarter (SNC). All district Headquarters (DNCs) are connected to State Head Quarter using 1Gbps/100 Mbps & 34 Mbps integration with NIC &16 Mbps as a backup from BSNL leased circuits. Similarly, all Sub Divisions/ Blocks (BNCs) are further connected to their respective District Headquarters (DNCs) using 16 Mbps leased links. Last mile connectivity at SNC and DNC level PoPs is given on Ethernet over Optical Fibre Cable (OFC) and terminated on RJ45 port of Routers. However, at SDNC/BNC level PoPs, last mile connectivity is on copper media and terminated on E1 port of Router.

Logically, the PAWAN network has been divided into two parts namely:

  • Verticalconnectivity:The vertical connectivity refers to the PAWAN Backbone. It is implemented using three-tier architecture with the State Headquarter (SNC) connected to the each District Head Quarter (DNC) which in turn gets connected to the each Subdivision/Block Head Quarter (SDNC/BNC).
    • Each SNC, DNC and SDNC/BNC point of connection is called a Point of Presence (PoP), which is a point of bandwidth aggregation for several network links getting connected at this point. The bandwidth provisioning for network connectivity between all the above PoPs is a minimum of 2 Mbps. Presently, the connectivity provisioning between every SNC and DNC is for 1 Gbps and DNC to every SDNC/BNC is 16 Mbps. PAWAN Backbone is through conventional leased lines, and all PAWAN backbone leased lines links terminate on the routers placed at each PAWAN POP.
  • Horizontal connectivity: The Horizontal connectivity of PAWAN is composed of horizontal offices spread across the State. All vertical PoPs of PAWAN have further provision for Horizontal connectivity. In horizontal connectivity, the government offices at each tier are connected to the respective PoPs.
