While open-source network mapping tools can create a physical network map, they may not offer automated scanning to ensure the map is always up to date. There are three levels of maps to consider-physical, logical, and functional.Ī physical network map diagrams all the actual components of your network, including cords, plugs, racks, ports, servers, cables, and more. It shows the type of network topology (bus, ring, etc.), and how the data flows between the physical objects in your network.Ī physical network map gives you a visual representation of all the material elements of your network and the connections between them.Ī logical map is more abstract than the physical network map. This includes IP addresses, firewalls, routers, subnets and subnet masks, traffic flow, voice gateways, and other segments of the network. To note: Since logical and physical network maps depict the same network environment from two different perspectives, it’s best to use both types to get a more comprehensive look at your network.Ī functional network map shows you how application traffic flows through the network physically. These types of network maps are only as useful as they are accurate, which means you need an appropriate and high-quality tool. Network mapping is the process of visualizing all the devices on your network, how they’re connected, and how the overall network is structured. The network map generally equips you with information about whether the network is functioning properly or whether any particular device has a problem. Networks are set up in different structures, also called topologies.
The structure can have a major effect on how your network functions, what happens when a device or server goes down, and how complex it is to manage. Tree – In a tree topology, a server has multiple branches of nodes coming off it.Ring – In a ring, network the nodes are arranged in a circle, and data can flow around the circle in one or both directions.Bus – A bus network is set up in a straight line, allowing data to flow through the network from the server to each node one by one.Here are the main network topologies to be aware of: When you map your network, you’re basically mapping its topology into a visual network diagram. Mesh – A mesh network has connections between all the nodes and servers, like a lattice or mesh.Star – A star topology has one central node with all others coming off it in a star pattern.With ring and bus topologies, a problem with one node can cause the whole network to go down This is a bit more robust than a bus or ring topology, as with a tree topology, if one of the branches has a problem with a node, the rest of the network will still function.
