A closer look at enterprise LANs
What does an enterprise local area network look like? Picture a private network that connects all the devices in a big company—computers, servers, printers, and more. Unlike your basic home network, an enterprise LAN is built to handle big data loads, faster speeds, and more reliable connections. It keeps communication easy and data flowing between teams without interruptions.
Routers and switches do the heavy lifting, making sure important tasks don’t get stuck in a digital gridlock. With backup systems in place, an enterprise LAN keeps things on track even when issues pop up. It's the network that works hard so that you don’t have to stress about it.
Key components of an enterprise LAN
An enterprise LAN offers LAN network solutions that keep your business connected and efficient. Think of it as the behind-the-scenes hero that stops your team from shouting, “Why is the network down?” To really understand an enterprise LAN, we’ll want to break down its main parts.
Network hardware
This is the core of any enterprise LAN and includes high-performance routers, switches, and access points. Each part has its own job to keep data moving and ensure devices can “talk” to each other.
Routers
Routers are the directors of network traffic, sending data packets between networks and linking your local network to the Internet and beyond. In an enterprise, these routers handle traffic between multiple LANs and outside connections to keep data moving quickly and efficiently.
High-quality routers often come with:
- Load balancing to spread out traffic
- Quality of Service (QoS) to prioritize important data
- VPN support for secure remote access
Switches
Switches work within the local network, connecting devices like computers, servers, and printers. By using MAC addresses, they only send data where it needs to go, cutting down on unnecessary traffic and keeping things efficient.
Enterprise switches often include:
- VLAN support to create separate network sections for better security and performance.
- Power over Ethernet (PoE) switches send power to devices like IP phones and access points straight through the Ethernet cable.
Access points
Access points (APs) let wireless devices connect to the wired network, giving employees the freedom to move around without losing their connection. Top-tier APs often have tech like multiple-input multiple-output (MIMO) to boost performance and keep users connected as they move around.
Network servers
Network servers are the brains of the operation, handling various services for other devices.
The different types of network servers include:
- Application servers that run tools and programs like email services or databases
- Storage servers, which hold large amounts of data, making it easy to access and backed up for safety
- Database servers that store structured data and support data-driven apps and decision-making
Building an enterprise-grade network setup means using high-performance routers, switches, and access points that can handle whatever your business throws at them. It’s like building a house with sturdy walls instead of leaning on cardboard.
Cabling
Cables make up the physical layer of an enterprise LAN. Ethernet and fiber optic cables are the main types used.
Ethernet cables (like Cat6 or Cat6a) offer a solid balance of speed and cost. Depending on the type, they can support speeds between 1 Gbps and 10 Gbps.
Fiber optic cables are your go-to for high-speed and long-distance data transfer. They’re immune to electromagnetic interference, which makes them perfect for areas with lots of electrical noise. Fiber is typically used for connecting different parts of a large office or even between data centers.
Security systems
Wondering how to secure an enterprise LAN? It’s going to take more than just locking the doors. Firewalls, Intrusion Detection Systems (IDS), and encryption are like your network’s personal security guards, always on duty to keep threats out.
Firewalls act as gatekeepers between your network and the outside world. They filter traffic, block suspicious activity, and provide the first line of defense against potential threats. Meter includes these features in our patented Security Appliance.
Options include:
- Hardware-based firewalls
- Software-based firewalls
- Hybrid setups
An IDS will watch for suspicious activity and alert admins or take automatic action.
Types include:
- Network-based (NIDS)
- Host-based (HIDS)
Encryption makes sure data sent over the network stays private. It encrypts data before sending and decrypts it on arrival, so any sensitive information stays protected from prying eyes.
Types of enterprise LAN networks
Enterprise LANs come in different flavors, each designed to fit specific business needs. Knowing these types helps you choose the right setup for your organization.
Wired LAN
A wired LAN connects devices with physical cables, giving you stable and fast connections. This type is great for places where mobility isn’t a top priority, like data centers, manufacturing floors, and traditional offices. Ethernet cables are the go-to options, supporting speeds from 1 Gbps and up.
Wired LANs are perfect for tasks that need steady, high-speed connections and low latency. They’re best for database servers, desktop workstations, and other systems that can’t afford downtime. Plus, they’re less likely to be affected by interference, unlike their wireless cousins.
Wireless LAN (WLAN)
A WLAN connects devices through Wi-Fi, ditching the need for cables. It’s perfect for places where people are always on the move or where dealing with wires is a nightmare. Wireless access points keep everything running and come with the latest Wi-Fi standards that offer faster speeds, better coverage, and more room for all those devices we can’t live without.
WLANs thrive in flexible spaces—think hot-desking offices, busy retail shops, and schools full of tech-savvy students. The best part? You can connect from almost anywhere in range, making mobility and access simple and effortless.
Hybrid LAN
A hybrid LAN gives you the best of both worlds, blending wired and wireless connections. It’s perfect for places where some devices need the solid, no-nonsense reliability of Ethernet while others thrive on the freedom of Wi-Fi. Think of servers and desktop PCs staying happily tethered with cables for stability while laptops and phones roam free on Wi-Fi.
A setup like this shines in big offices, campuses, or anywhere that needs a mix of sturdy connections and flexible access. You get reliable performance for the heavy lifters and wireless convenience for everything else.
Campus LAN
A campus LAN connects multiple buildings within a specific area, like a university or a corporate campus. This type of LAN covers a much larger space than standard LANs and needs high-capacity infrastructure, often using fiber optic cables to keep data moving quickly across distances.
Campus LANs have more complex setups to handle the heavy data loads and link different locations efficiently. They’re built with redundancies to keep things running even if part of the network hits a snag. It’s designed to keep big sites connected and humming along.
Data-center LAN
A data-center LAN is custom-built to handle huge amounts of data with high speed and minimal delay. They use high-capacity switches, fiber optics, and other advanced tech to keep up with the demands of data processing and storage. Data center LANs focus on scalability, speed, and security, often featuring load balancing and failover options to keep everything moving along.
