A comparison of network diagram software finds a number of tools exist to generate computer network diagrams. Broadly, there are three types of tools that help create network maps and diagrams:

Sketchpad: Free online drawing application for all ages. Create digital artwork to share online and export to popular image formats JPEG, PNG, SVG, and PDF. Draw.io will slowly transition to become diagrams.net during 2020 for security reasons. Nothing will change for you, apart from seeing a different URL and logo. Www.draw.io will continue to serve the application correctly, we won’t even redirect you. The Atlassian integrations are not affected, they will continue to be branded as draw.io. Draw.io is a handy and free diagramming and flowchart application that allows you to quickly draw out your content logically. It boasts strong, real-time collaboration features if connected to a Google account and all the tools you need for creating simple data representations.

Hybrid tools
Network Monitoring tools
Drawing tools

Network mapping and drawing software support IT systems managers to understand the hardware and software services on a network and how they are interconnected. Network maps and diagrams are a component of network documentation. They are required artifacts to better manage IT systems' uptime, performance, security risks, plan network changes and upgrades.

Hybrid tools[edit]

These tools have capabilities in common with drawing tools and network monitoring tools. They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams. Typical capabilities include but not limited to:

Displaying port / interface information on connections between devices on the maps
Visualizing VLANs / subnets
Visualizing virtual servers and storage
Visualizing flow of network traffic across devices and networks
Displaying WAN and LAN maps by location
Importing network configuration files to generate topologies automatically

Examples of commercially-available hybrid tools include:

Network monitoring tools[edit]

Some network monitoring tools generate visual maps by automatically scanning the network using network discovery protocols. The maps are ideally suited for viewing network monitoring status and issues visually. Typical capabilities include but not limited to:

Automatically scanning the network using SNMP, WMI, etc.
Scanning Windows and Unix servers
Scanning virtual hosts
Scanning routing protocols
Scanning connection speeds
Performing scheduled scans
Tracking changes to the network

Drawing tools[edit]

These tools help users to create network topology diagrams by adding icons to a canvas and using lines and connectors to draw linkages between nodes. This category of tools is similar to general drawing and paint tools. Typical capabilities include but not limited to:

Libraries of icons for devices
Ability to add shapes and annotations to maps
Ability to create free-form diagrams
