5 Best Network Diagram Tools for Network Designers


A network diagram tool is an important asset for a network designer. It facilitates the development of highly secure and efficient computer networks. In this article, we will be discussing what a network diagram is, how it works, and the best network diagram tools to use.

What is a Network Diagram and How Does it Work?

A network diagram is a visual representation of a computer network that shows how the many components of a computer network interact. Routers, hubs, firewalls, devices, and other components are included in it.

A network diagram may provide a simple overview of the network or a more complex network diagram, depending on its scope and purpose.

A Local Area Network (LAN) diagram, for example, might depict individual device IP addresses. A Metropolitan Area Network (MAN) diagram, on the other hand, might depict areas or buildings with a single node. There are two types of network diagrams: physical and logical.

  1. Logical Networks DiagramsThe flow of data via a network is depicted in a logical network diagram. Subnets (i.e., VLAN IDs, addresses, and masks), routing protocols, network devices, and firewalls are typically displayed in a logical network diagram.
  2. Physical Networks DiagramsAs the name implies, a physical network diagram depicts the actual physical layout of network components. Hardware and wires are included. This style of graphic, similar to a floorplan, gives a bird’s-eye view of the network in a physical place.

Network switch diagrams, computer network diagrams, and network security diagrams are examples of several types of network diagrams. Each of these network diagrams concentrates on a single network component or element.

What are the Benefits of Network Diagrams?

Network diagrams are useful for a variety of reasons, but most importantly because they show how network components interact. Network diagrams can assist you in planning the construction of a new home or business network, as well as coordinating upgrades to an existing network.

A network diagram can also be used to report and debug networking issues, as well as to ensure that your company meets PCI and other compliance requirements.

Network diagrams are frequently used by businesses as documentation for external communication, onboarding, and training. When it comes to onboarding new team members, a clear and detailed network diagram can save a lot of time. It also serves as a useful reference point for rapidly and effectively resolving network difficulties.

Network diagrams can also be used to keep track of components, communicate essential information to a vendor for a request for proposal (RFP) without having to reveal confidential data, sell a network plan to stakeholders, and propose high-level Syslog infrastructure changes.

What are the Benefits of Network Diagramming Tools for Businesses?

Creating a detailed network diagram might take a long time and require a lot of resources. Your network diagram should be developed by a highly experienced member of your team who is knowledgeable about various forms of network diagrams to ensure accuracy.

Network switch diagrams, computer network diagrams, and network security diagrams should all be included. The person or team in charge of drawing the network diagram should have a solid understanding of which form of diagram is suitable for your company’s needs.

By constructing the network design for you, an automated network diagram tool can save you time and resources. Some of the best network diagram software can automatically detect your network and map it out based on your preferences.

Every network administrator’s arsenal should include network diagramming software, which ensures that your network diagrams are correct, up to date, and easy to understand.
