Best Network Diagramming Solutions on the Market

What Is a Network Diagram?

A network diagram is a visual representation of all of the connections on a network. With a comprehensive network visualization, viewers can see how devices, connections, pathways, and data flows are currently set up on their network.

Some of the main approaches to network diagramming include:

Manual network diagram

This type of network diagram may be useful for larger networks because you can manually draw network components and connections at a granular level. However, your diagram will need to be audited and updated frequently as your network changes over time.

Semi-automated network diagram

The semi-automatic approach to network diagramming automates the process of auto-discovery, or automatically identifies new devices as they join the network. However, users are still tasked with manually making the diagram connections.

Automated network diagram

This approach automates the device discovery phase and auto-generates a network diagram to match the changing network in real time. This type of diagram solution typically offers templates, stencils, and other features, though it lacks some of the customizability in manual and semi-automated diagram tools. 

Logical network diagram

Logical network diagrams are focused less on the physical hardware and applications on a network and more on how and why everything connects the way it does. A logical network diagram typically includes information about subnets, routing protocols, and hardware like firewalls and routers that show how data flows from place to place.

Physical network diagram

A physical network diagram is more like a blueprint. It focuses on showing the physical layout of hardware and how every cable, router, and device physically connects.

Important Network Diagram Tool Features

  • Data and diagram sharing: There are several reasons why a network diagram tool user might want to share their diagram with outside users or applications. Look for tools that offer native or third-party integrations for collaboration tools, as well as the ability to share diagrams with office suites and other diagram applications.
  • Customizability: Every network layout and diagramming need is different. Look for solutions that allow you to make manual adjustments to the layout, the design library, and other features as needed. Open source models in particular offer high levels of customization to users.
  • Design and visualization templates: Most network diagramming tools include extensive design libraries for shapes, icons, stencils, and templates. Check with the sales team to see if their visualization features match your needs and/or if you can add to the design library on your own.
  • Import and export flexibility: It’s common for enterprise networks to switch from one diagramming tool to another as their needs change. That’s why it’s important to invest in tools that easily import and export diagram data, either directly to the other tool or via user-friendly file formats.

Enterprise Benefits of Using Network Diagram Solutions

Network diagrams, especially when regularly updated through diagramming solutions, offer several benefits to the enterprise network:

Preparation for a new network design

Whether a new company is building a network or an existing company is looking to revamp its network design, network diagramming solutions can help architects to visualize their new network infrastructure before committing to the design. Network diagrams, whether logical or physical, can help network architects to visualize network issues and to optimize their plans proactively.

Network auditing support

Especially as networks grow to meet enterprise needs, it becomes increasingly difficult to manually review and update outdated network components. With a network diagram, your team now has a frequently updated visual representation of how the network is currently set up and where different outdated components live. Network auditing projects frequently rely on network diagramming software because of the detailed, accessible visual data they provide.

Network data democratization

Unless you’re a network expert or a data scientist, most network data documentation and explanations are too complex to fully understand. Network diagrams make network data visual, thus making it possible for less technical administrators and executives to understand the network’s core components.

Accessibility for larger networks

Most network diagramming software allows you to customize your diagram and dashboard to the exact network features you want to view. You may also have the option to create more than one map if you have several different layers or types of network connections that you want to visualize. Larger networks can be especially difficult to visualize, but with the single dashboard and customizable features in a network diagram, users can see the most relevant parts of a larger network at once.
