Network Diagram Software & Mapping Tools


A diagram costs a thousand words. And one of the most important diagrams is a network diagram. This guide will provide you with information about how to draw it, its elements, paths, requirements, and network diagram software. You can find tools that work on Windows, Linux, Mac OS X, Android, and web-based online platforms.

Most important sections are:

Definition and Elements

The network diagram is a visual representation of network structure. It can be general or very detailed depending on the purpose of this diagram.

Usually, business units prefer something more general at a glance. Technical units, on the other hand, prefer more details.

Here is one example of general diagram:

network diagram software example

In any case, network diagram has elements and connection (protocols) between them.

The most important elements are:



Cloud element – it represents a part of a network which is maintained in a cloud or it is hidden and out of visibility.

Network router – usually shows the border between networks.

Firewall – a place where security firewall is used.

Server – Servers can have different icons in case they are application servers, web, virtual, etc

Computer – there are different items for PC, laptop, terminal.

Database, storage, back-up, archive.

Mainframe icon

There are many more network diagram items but the above are enough to have some basic understanding.

Software Requirements

Once again there is no best solution for network diagram software. But there are two main options.

Standard Diagramming Software – If you want general network diagrams in a fast and easy way you can use standard software for diagrams. The diagrams are useful for business purposes, presentations, fast and easy knowledge transfer.

Main requirements include options for general network icons, Sisco icons, Rack icons, peripheral devices and telecommunication icons, 3D icons, etc.

You can have MicrosoftViso,, Lucidchart, etc and they will work fine.

The main disadvantage is that you have only static network diagram and you need to change it manually. There are no network mapping features or other management options.

The Standard Diagraming tools will not be listed in this page. More explanation about them you can find in Project Management tools section.

Automate Network Mapping Software – well if you have large enterprise or support many networks you may need more than a static picture. Network mapping software offers many options to manage your network and its graphic visualization. Most important of them is automated creation of network diagrams.

Some of the most important requirements for this software are:

  • Map accuracy
  • View network devices
  • Import data
  • Scan network
  • Routing
  • Information flows
  • View current network state
  • View previous states
  • Export data

The next sections will provide reviews and more information for these automated network diagramming software.
