Statewide Area Network: Key Features and Impact Explained

The Statewide Area Network (SWAN) is becoming an essential infrastructure for enabling the delivery of public services across states, driven by the demand for quicker and more intelligent governance. This reliable network connects all State, District, and Block Headquarters for secure and high-speed communication. As an initiative under India’s National e-Governance Plan, SWANs are used to enhance administrative efficiency and the availability of government services. 

Unlike the traditional WAN, the SWAN has been developed to meet the unique needs of the public sector, providing improvements in scalability, security, and ordered connectivity. Here, we’ll discuss the operation, benefits, and future challenges of SWANs, in particular their transformative impact. We will also explore the significance of SWANs for digital governance, as well as their history and contemporary uses.

What is Swan Network?

The State Wide Area Network (SWAN) is a secure, high-speed network connecting government offices at the state, district, and block levels. It facilitates efficient G2G and G2C services in a Closed User Group (CUG) network for secure data communication.  Introduced in 2005 as part of the National e-Governance Plan (NeGP), SWAN is in operation in all 29 states and six union territories. Consequently, it provides a unified backbone for voice, video, and data communication, enhancing government efficiency and service delivery. 

Key features include:

• High-speed connectivity for seamless communication among government offices.
• Secure Closed User Group(CUG) network for safe data exchange.
• Unified infrastructure supporting voice, video, and data.
• Scalable design to meet growing governance needs.
• Interoperability with national and state-level applications.
• Reliable performance with redundancy and backup systems.
• Centralized monitoring via Network Operation Centers (NOCs).

Understanding WAN and Its Role in SWAN

Before we dive into what a Statewide Area Network (SWAN) is, let’s first differentiate between a SWAN and a Wide Area Network (WAN). A WAN consists of local-area networks (LANs) or other networks that communicate with each other, essentially forming a network of networks. The most popular example of the WAN is the Internet, which interconnects multiple networks across the globe by using routers, switches, and other telecommunications protocols.

In the Statewide Area Network(SWAN), the WAN infrastructure is used to form a state-level network. SWAN utilizes WAN technologies to provide access to governments at various administrative levels. By incorporating WAN technology into SWAN, data, voice, and video can more easily move across the state in support of the State’s digital transformation objectives.

How a Statewide Area Network  Works

A hierarchical network structure of a Statewide Area Network (SWAN) provides a multilevel connectivity for seamless communication between cross-administrative levels. Here are the main elements of the system and how it works:

1. Network Architecture

• Points of Presence (PoPs): These are the network nodes at the State, District, and Block levels. Each PoP is a hub of connectivity across the government offices in its formation. For example, in the statewide area network MP, there are 380 PoPs throughout the state, providing extensive coverage.
• Vertical Connectivity: This refers to the backbone connectivity between state headquarters, district headquarters, and block-level offices. Moreover, high-capacity links, often fiber-optic, ensure fast and reliable data transmission.
• Horizontal Connectivity: At each level of government (state, district, or block), these horizontal links connect a number of governmental departments to the relevant PoP. As a result, departments such as revenue, police, and treasury can pool and exchange resources.

2. Technologies Used

Statewide Area Network (SWAN) employs standard technologies, including:

• Leased Circuits: Dedicated lines for reliable connectivity.
• VSAT (Very Small Aperture Terminal): Satellite-based connections for remote areas.
• Radio Frequency: Wireless links for challenging terrains.
• Optical Fiber: High-bandwidth connections for urban and semi-urban areas.
• Ethernet and Dial-Up Circuits: Used as fallback options in specific scenarios.

3. Service Models

Statewide Area networks are typically implemented through one of two models:

• Public-Private Partnership (PPP) Model: In this model, private network operators partner with states to implement, operate, and maintain the SWAN. A private partner is selected through a competitive bidding process, and the network is operated on a build-own-operate-and-transfer (BOOT) basis for a specified duration (e.g., 5 years). Several states in India have adopted this model due to its low cost and scalability.
• National Informatics Centre (NIC) Model: Under this model, the primary implementation agency is the NIC, which is a government organization. The NIC contracts an agency under the Facility Management Service (FMS) scheme to manage the facility on a daily basis. Moreover, the Department of Information Technology (DIT) funds the establishment and maintenance of the SWAN for five years.

4. Monitoring and Maintenance

SWANs are reviewed by a third-party audit (TPA) organization to maintain high quality. The TPA is particularly concerned with fulfilling SLAs in the network, encompassing a set of performance metrics such as latency, uptime, and bandwidth. Furthermore, the audit proceeds for five years after the last acceptance test of the network. Therefore, it is able to provide long-lasting quality and reliability.

Historical Context of Statewide Area Network  

The National State Wide Area Network was established in March 2005 as part of the NeGP, but some states implemented their statewide networks earlier. Notable examples include:

1. Andhra Pradesh Statewide Area Network (APSWAN): Launched in 1999, APSWAN was India’s first statewide area network, linking government organizations for voice, video, and data, and is used for e-governance purposes. The Build-Own-Operate-Transfer (BOOT) model enhanced administrative efficiency and served as a global benchmark.
2. Gujarat Statewide Area Network (GSWAN): Launched in 2001, the GSWAN network connects over 3,000 government offices in Gujarat, enabling the provision of e-governance services, including video conferencing and data sharing. Its powerful infrastructure enables citizen-facing applications and disaster recovery.
3. Jharkhand Statewide Area Network (JharNet): Established in the 2010s, JharNet utilizes both optical fiber and wireless technologies to connect 90% of the government offices in Jharkhand, enabling efficient services for its citizens. Its layered architecture offers a scalable and dependable e-governance deployment.

Statewide Area Network (SWAN) vs Traditional WAN
