A network is an organization’s critical resource as it plays an important role in enhancing productivity and profitability for the organization.
As an IT administrator, your job is to keep the organization’s network up and running at all times and secure it in the best way possible.
But it is not easy, especially if you have to maintain a large network with thousands of devices connected to it and this is why you need good network diagnostic tools and software.
One such important tool is a network diagram. As the name suggests, this diagram is a blueprint of the network and gives you a complete picture of how the network is built, how many devices connect to it. The different interconnections that exist between different networks, IP addresses, configuration parameters, and so much more.
Such detailed information will make it easy for you to identify problems and troubleshoot them at the earliest.

Network Topology & Diagrams
There are many tools available to create and update network diagrams, so can stay on top of your network’s availability and functioning at all times, as well as knowing where each individual network device is physically located in your building/s.
Broadly speaking, there are two kinds of tools – ones that create the a network topology or diagrams for you and the other that gives you a digital canvas so you can create your own network diagram.
You can choose either of the two kinds of tools, depending on your requirements.
Some IT administrators prefer an automated tool as it takes a lot of work off their hands while others prefer to draw the diagram by themselves, so they can better understand its connections and functioning.
The first three tools mentioned below are automated ones while the next three provide a digital canvas and many convenient features to make it easy for you to create your own network diagram.
The Best Network Topology Maps & Diagram Tools
Let’s take a detailed look at each of these tools, along with some screenshots and where to download them.

To conclude, network diagram tools are necessary to give you an idea of your network’s layout and the devices that are connected to it.
While some tools automatically check your network and create a map for you, others give you a digital canvas on which you can draw your network diagram for better understanding and readability.
We hope the above-mentioned detailed information about the tools that belong to both categories help you to make informed decisions.
