14 Best Network Diagram, Mapping and Topology Tools

Over the past decade or so, Network Diagram tools have become an essential part of modern administrative toolkits. As companies begin to maintain more complex IT infrastructure, the ability to map these complex landscapes becomes even more important. After all, if you don’t have a clear understanding of your network topology, you don’t have complete network transparency. Network mapping is a key element in network monitoring tools. Getting a visible representation of each of your network devices and their relationships gives you a context for all of your equipment monitoring tasks.

A tool that produces a diagram of your network and maps its connectivity from head to toe can tell you a lot about your technical infrastructure. This not only increases your efficiency but also enhances your ability to troubleshoot problems. You simply cannot respond to performance concerns intelligently unless you have a thorough understanding of your network’s geography.

By understanding where your hardware sits in your network infrastructure, you’re better able to address problems promptly when they occur. You will also be able to maintain a targeted approach to cybersecurity ensuring that you systematically protect every system available on your network. In most cases this will be achieved by identifying faulty hardware or optimizing your network.

What is a Network Map?

As the name suggests, a network map is a visual diagram of your network that displays each device within your local IT environment. A network map details the location of components like routers, VLANs, access points, firewalls, switches, hosts, laptops, and computers. This map acts as a schematic guide to your network.

While a network map can be drawn by hand, doing so is very complex and inefficient. Today most enterprises choose to employ a network diagram and topology tool to automate the process of drawing up their network. This ensures they can can produce a diagram promptly and scale it to the needs of their enterprise in the future. Network monitoring tools usually include a network mapping module.

Why Do I Need a Network Diagram and Mapping Tool?

The main reason administrators use network diagram tools is to save time. Creating a network map from scratch without the help of a dedicated program is very complex and time consuming. In addition, once you’ve taken the time to draw up your map, its most likely going to be out of date by the time it is finished.

The IT infrastructure of most large organizations is constantly evolving. A network diagram tool has the potential to keep up with these changes and ensure that you always have an accurate depiction of your network on hand for reference. Drawing up network diagrams manually simply takes too long to keep up with the changes occurring on most networks (particularly enterprise grade networks!).

One of the most well-known network mapping tools is SolarWinds Network Topology Mapper. Tools like Network Topology Mapper are great because they offer an auto-discovery feature that automatically identifies devices on a network and charts them on a map. This map can then be used as a network guide for administrators or used for PCI and FIPS-142 compliance. By using tools like Network Topology Mapper, you end up with a clear overview of your equipment.

Utilizing a network diagram and mapping tool is the only way to design a network diagram promptly in way that keeps pace with the evolving infrastructure of a modern IT environment. Having an up-to-date map is fundamental to troubleshooting your network and optimizing services.

In other words, topology plays an integral part in how your network performs. For example, the longer a data packet travels on your network, the longer your communication time. It thus makes sense to design a network path that is as efficient as possible. Below we’ve produced a short list of essential features of network diagram mapping tools:

  • Autodiscovery – Top of the range network mapping tools can discover devices automatically, and run port scans to see which services are up and running.
  • Troubleshooting – Part of effectively troubleshooting a network is having a top-down view of what’s happening on each individual host or device.
  • Live Monitoring – You can see what’s happening on your network live and receive alerts when changes occur in your infrastructure.
  • Intelligent Scalability – You can use a network mapper to run reports on your network and identify which components need to be upgraded.

Mapping tools for network analysis

The network map assists you with analysis tasks as well as day-to-day monitoring. If the network suddenly slows, it is important to isolate whether the problem is truly system-wide or really the fault of one piece of equipment. Live network maps that graphically represent the statuses of all of your network’s elements instantly highlight the location of a problem.

Getting a map is often the starting point of any project to expand a network in order to serve more users or include new software services. Capacity planning needs to be performed on two levels — for the network as a whole and also on a per-device basis. Impact studies of changes in the network can only be performed when you understand which neighboring devices attach to any network segment that is the subject of change.

2. Paessler PRTG Network Mapping Tools (FREE TRIAL)

The Paessler PRTG infrastructure monitoring suite features network mapping tools that offer you a range of formats. The most eye-catching map that PRTG produces is its sunburst view. This shows circles of applications together with the services and hardware that supports each. The sunburst view can be applied to a range of map data.

Other mapping options include a straight-forward plot of all of the devices in the network with connections depicted as straight lines. The standard map shows icons for the nodes. Each icon takes the form of the device type. You can customize the icons if you like. Color-coded statuses are shown for each device. The links between devices are also color-coded with healthy link shown in green and problem links colored red. This is a very easy-to-read map and it gives you statuses at a glance as well as the relationships and dependencies between devices.

Other map options give you templates that you can adapt and personalize. A building plan will show the location of each device on your premises and even integrate photos of your offices. Another option, which is great for WANs, plots your network on a real, zoomable map of the world.

The focus of each map can be altered on command to show only Layer 2 or Layer 3 devices. You can feature applications, protocols, and throughput. You can also create your own custom maps using a mapping module that links through to the underlying data of the device inventory.

The fact base that underpins any mapping format is the register of equipment and software that you command. This database is assembled automatically by PRTG when you install the software. The network discovery function keeps running, so any changes that you make to your resources gets registered by the monitor. Those changes get rippled through to your network maps automatically.

PRTG installs on Windows. However, you can opt to use the monitor as a cloud-based service. The data collectors of the monitor are called “sensors.” You can get PRTG for free to monitor up to 100 sensors. Paessler offers a 30-day free trial with unlimited sensors so that you can assess the software.

Lucidchart is one of the less known network mapping platforms that packs a tremendous punch. If you’re looking to fast track your map production, then look no further. From the outset you can launch straight into a template and start building your IT environment. This allows you to hit the ground running and get the basic elements down before you add your own unique network tools (it even has iPhone and Android mockups!).

For a single user, Lucidchart comes in at $4.95 (£3.66) a month but if you want to use the program with an entire team of people, it’s available for $20 (£14.77) a month for three or more people. You can also import Visio files straight into Lucidchart if you have existing diagrams you wish to use. Although you don’t have an inbuilt auto-discovery feature, UVexplorer is now compatible with Lucidchart, so you can use that as an ‘auto discovery plugin’. This platform is available on the Lucidchart website here.

5. Intermapper

In terms of network diagramming solutions, CADE takes a back-to-basics approach. While there is no fancy GUI, you’ll find that there is an extensive 2D vector editor. CADE is a free application that can be downloaded online. This makes CADE a good choice for teams looking for a suitable remote deployment platform. As a welcome addition, remote users can contribute in real time to a drawing on the web.

Once you’ve finished creating your drawings, you can also export them in EMF, JPG, XAML or PDF format. One of the more unique features CADE offers is its “draw cable” functionality. You can draw up unique cables to differentiate between devices. In the event that you need to look at your network more closely, you can simply zoom in (this is invaluable when dealing with an enterprise grade network).

The only issue with CADE is that it lacks an auto discovery feature. While it is incredibly flexible in its design potential, larger enterprises looking for a tool with scalability should go elsewhere. However, if your network environment is unlikely to change drastically within the next 12 months, then this is a solid tool. CADE can be downloaded for free here.

7. Dia (Free)

Visio comes in at a hefty price tag of $299 (£220) for the standard version and $590 (£435) for the pro version. For this price you buy the luxury of using over 70 templates and thousands of IT image objects to map your network.

One of the most noticeable things about Visio is its slick design. The default diagrams look very sharp, which makes it more convenient to draw distinguishable network maps. Unfortunately, Microsoft Visio is let down by its price. Though it offers an extensive suite of network mapping features, it doesn’t offer an auto-discovery feature. That being said, if you’re looking for a diagramming tool made specifically for network administrators, then look no further. Visio can be downloaded from the Microsoft website here.

13. Ipswitch WhatsUp Gold

WhatsUp Gold is a network device monitor with a number of add-ons available that extend the reach of monitoring through to your network traffic, servers, and applications. In each module, the installation completes with a system sweep. This will discover all of your IT property and log it. The device and software registries get interpreted automatically into maps. The discovery process is continuous and will update the registries automatically. Those changes also get shown on updated maps without any manual intervention.

The discovery and mapping functions are not limited to covering just the devices on your premises. It can extend to cloud services and also include infrastructure located on remote sites. So you can unify your operations and view all of your equipment, services and software in one central map.

The standard network map shows your Layer 2 and Layer 3 devices plus servers and the links between them. The devices are shown by a circular icon and the rim of each circle shows a status color: green for healthy and red for problems. The connections between devices are all shown on the map. You can customize the generated maps to make the layout more readable. You can also alter the views of the maps to show statuses and traffic flows for a specified application or protocol.

If you use virtualization on your system, you can get WhatsUp Gold to generate a map showing all of the linked elements that compose those VMs.

WhatsUp Gold and its add-ons all install on Windows. You can get a 30-day free trial so that you can assess the system before you buy.
