Logical topology modeling · every OSI layer
Draw networks the way engineers actually think.
NetSpec Studio is a diagramming canvas for computer network engineering. Model every plane of your stack — from physical media up to application services — and toggle OSI layers to isolate what matters.
All seven OSI layers
Physical, Data Link, Network, Transport, Session, Presentation, Application — color-coded and independently toggleable.
Drag-and-drop canvas
Snap-together routers, switches, hosts and services with an infinite pan/zoom board.
