A concise guide that explains network topology concepts, documentation methods, and design best practices.
The No‑Sweat Guide to Network Topology, authored by Kevin Dooley, introduces the importance of documenting network layouts for troubleshooting, planning changes, and audit compliance. It covers basic topologies, network layers, Ethernet, bus and switched designs, segmentation, VLANs, routing, and high‑availability strategies.
The guide also provides practical instructions for drawing network diagrams, using both manual methods and automated tools, and includes tips for internal firewall design and security zoning. It ends with a list of helpful resources for deeper study.
Segmentation isolates traffic into separate broadcast domains, making it easier to control access with firewalls and limit the spread of potential attacks.
