What Are Active Network Services and Why Do You Need Them?

Computer networks are one of the essential pillars of organizational infrastructure in the digital age, playing a critical role in the daily operations and productivity of businesses. Once the physical infrastructure (passive services) is in place, the next vital step is active network services—a key component that ensures stable, logical, and purposeful communication between network devices.

Active services refer to the set of operations involved in activating, configuring, and managing network devices such as switches, routers, firewalls, and access points, as well as software-based services like antivirus systems, bandwidth management tools, and access control systems. During this phase, data and signals are processed, routed, and managed within a defined structure to ensure both network security and performance.

This process requires deep technical knowledge, a thorough understanding of network devices, and hands-on experience in network architecture design and deployment. For this reason, the configuration and proper management of active network components should always be entrusted to qualified professionals.

With over 22 years of experience in designing, implementing, and supporting enterprise networks, SUNNET delivers comprehensive active network services, including consulting, network architecture design, hardware and software deployment, security management, and professional support.
Our goal is to guarantee the stable, secure, and high-performance operation of your organization’s network.

In the OSI model, active network services correspond to layers 3 through 7, encompassing all services that involve processing, routing, intelligent configuration, and security management.

What Do Active Network Services Include?

Active network services refer to the installation, configuration, and deployment of active hardware and software components within a network. These services play a key role in creating a stable, secure, and manageable communication environment for organizations.

At the first stage, active devices such as switches, routers, modems, access points, firewalls, and network-attached storage (NAS) systems are configured by experts to establish fast and reliable communication across different parts of the network.

Next, client and server operating systems (such as Windows or Linux) are installed and customized according to the specific needs of the network. Following this, software and network management services are implemented in a structured and integrated manner. These include:

✔ Installation and configuration of Active Directory for centralized user and resource management
✔ File sharing services
✔ Network-based antivirus systems
✔ Deployment of business-critical applications such as financial software, CRM systems, and administrative automation tools
✔ VOIP services for IP-based telephony
✔ Automated and scheduled backup solutions for organizational data

Each of these services requires specialized technical knowledge and is delivered by experts in the relevant fields. That’s why SUNNET provides these services through highly qualified professionals to ensure reliability, performance, and peace of mind.

Hardware Setup and Integration as Part of Active Network Services:
✔ Deployment of MikroTik and Cisco routers
✔ Configuration of enterprise-grade internet modems
✔ Setup of servers and NAS devices
✔ Firewall implementation to enhance network security
✔ Installation of wireless access points for wide-area coverage

SUNNET offers these services as part of a comprehensive, strategic approach, ensuring your network infrastructure operates with maximum efficiency, security, and scalability.

Active Network Services at the Server and Client Levels

On the server side, the organization’s needs are first thoroughly assessed, and based on the intended use, the required specialized services are selected and installed. These may include user management systems, file sharing, office automation platforms, financial software, data backup solutions, and more.
If necessary, virtualization is also implemented to improve efficiency and optimize server resource management.

On the client side, general user applications such as Microsoft Office, Adobe tools, antivirus programs, VPN clients, and other essential software are installed and configured according to the latest available versions.

Once these stages are completed, providing ongoing professional network support is essential to maintaining system stability, security, and regular updates. This support is a critical part of SUNNET’s active network services and is delivered by our experienced technical team.

Active Network Support Services at SUNNET

In the world of enterprise networking, active network support is one of the key pillars for maintaining system performance, ensuring security, and enabling future scalability. While the initial deployment of network hardware and services is essential, long-term stability and functionality are impossible without specialized, ongoing support—especially when it comes to active infrastructure and mission-critical software.

Network support may be required for a variety of reasons, such as troubleshooting technical issues, maintaining network integrity, upgrading hardware, or updating existing services. The technical team responsible for this task must have a deep understanding of the implemented infrastructure, along with the technical skills necessary to further optimize and expand the system.
