Understanding different types of networking services

In today’s interconnected world, networking services play a crucial role in ensuring seamless communication, data exchange and resource sharing across various devices and platforms. Understanding the different types of networking services can help you make informed decisions about your IT infrastructure, data and application sharing along with your connectivity needs.

Types of networking services

Explore the various types of networking services that connect and enhance our digital world, from local networks to cloud-based solutions.

1. Local Area Network (LAN)

A Local Area Network (LAN) is a network that connects devices within a limited geographical area, such as a home, office or building. LANs are typically used to share resources like printers, files and internet connections among connected devices. They offer high-speed data transfer rates and are relatively easy to set up and manage.

2. Wide Area Network (WAN)

A Wide Area Network (WAN) spans a large geographical area, often connecting multiple LANs across cities, countries or even continents. WANs are essential for businesses with multiple locations, enabling them to communicate and share data over long distances. The internet is the most common example of a WAN.

3. Metropolitan Area Network (MAN)

A Metropolitan Area Network (MAN) covers a larger area than a LAN but is smaller than a WAN, typically spanning a city or a large campus. MANs are used to connect multiple LANs within a metropolitan area, providing high-speed connectivity and efficient data transfer.

4. Wireless Local Area Network (WLAN)

A Wireless Local Area Network (WLAN) is similar to a LAN but uses wireless technology to connect devices. WLANs are commonly used in homes, offices and public spaces to provide wireless internet access. They offer flexibility and convenience, allowing devices to connect without physical cables.

5. Virtual Private Network (VPN)

A Virtual Private Network (VPN) creates a secure, encrypted connection over a public network, such as the internet. VPNs are used to protect sensitive data, provide privacy and enable remote access to corporate networks. They are essential for businesses who need to access resources securely from different locations.

6. Storage Area Network (SAN)

A Storage Area Network (SAN) is a specialized network that provides access to consolidated, block-level data storage. SANs are used in data centers and enterprise environments to improve storage performance, scalability and availability. They enable efficient data management and backup solutions.

7. Personal Area Network (PAN)

A Personal Area Network (PAN) is a small network that connects devices within an individual’s workspace, such as a computer, smartphone and wearable devices. PANs are typically used for personal data sharing and synchronization.

8. Cloud networking

Cloud networking involves using cloud-based services to manage and deliver network resources. It allows businesses to leverage the scalability, flexibility and cost-efficiency of cloud computing for their networking needs. Cloud networking services include virtual networks, cloud-based firewalls and load balancers.

Comparing the most common types of business networking

Now that you better understand the key differences and benefits of each networking service, let’s take a closer look at their benefits and capabilities to help you determine which approach is right for your business.

The four most popular types of networking solutions for business

Meeting the dynamic needs of modern enterprises requires networking solutions that offer flexible connectivity, centralized management and high speed (that doesn’t compromise on security) along with comprehensive support. These products offer you optimized network infrastructure while focusing on your core operations.

Network-as-a-Service (NaaS)

NaaS provides you with flexible, on-demand network services that can be scaled up or down based on your needs. This model allows companies to pay by the hour for what they use, enabling reduced costs and increased efficiency. Lumen NaaS offerings include a range of services such as SD-WAN, cybersecurity, IP VPN and other edge services, allowing businesses to adapt quickly to changing demands.

SD-WAN solutions

SD-WAN solutions are essential for optimizing network performance and providing reliable connectivity across multiple locations. They use software to manage and control network traffic to help provide better performance, security and flexibility compared to traditional WANs. Lumen® SD-WAN Solutions help you improve application performance, reduce costs and enhance user experience by intelligently routing traffic over the best available path on the #1 peered global network.¹

Ethernet services

Ethernet services offer high-speed, reliable connectivity for your business that requires robust network performance. These services are ideal for connecting multiple locations, data centers and cloud environments. Lumen® Ethernet Services provide scalable bandwidth options, low latency and high availability, making them suitable for a wide range of business applications and enabling seamless data transfer and communication.

Managed network solutions

Managed network solutions provide your business with comprehensive network management and support, allowing you to focus on core operations. These solutions include monitoring, maintenance and optimization of network infrastructure, enabling maximum uptime and performance. Lumen Managed Network Solutions offers expert support and proactive management, helping you reduce complexity, improve security and achieve networking goals.

Simplify network access, security and management while innovating for what’s to come

The need for on-demand services and NaaS is rapidly increasing as businesses seek more flexible, scalable and efficient networking solutions. Lumen is at the forefront of this transformation, offering a comprehensive suite of NaaS solutions that cater to the evolving needs of modern enterprises. According to a recent IDC commentary, “Lumen® Internet On-Demand is well articulated and can bring immediate value to customers.” IDC also notes, “This is a positive step that will help establish Lumen as an important provider of NaaS. Its road map will expand NaaS into networking services such as SD-WAN, security/SASE and other Edge services that witness a strong uptake in the future.”2

It’s equally important to ensure your networks and data are secure. Unifying network and security management with SASE solutions and managed services makes a world of difference to not only protect your networking services but also reduce cost and complexity while providing seamless access for remote and hybrid users. It’s network and security unified.

In addition to secure networking solutions, consider the importance of AI-ready networks. As artificial intelligence (AI) continues to revolutionize various industries, having an AI-ready network is crucial to support current and future applications. Lumen new edge fabric solutions are designed to meet these demands, enabling you to leverage AI technologies seamlessly. Integrate AI capabilities into your network infrastructure and enhance operational efficiency, improve decision-making and drive innovation.
