For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted for the purposes of showing the general relationship between the appliance and any such device.Ĭisco uses its own brand of networking symbols. In addition, when the scope of a diagram crosses the common LAN/ MAN/WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes. At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level, individual nodes may represent entire cities. ![]() If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.Īt different scales diagrams may represent various levels of network granularity. For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. ĭepending on whether the diagram is intended for formal or informal use, certain details may be lacking and must be determined from context. For example, in the hypothetical local area network pictured to the right, three personal computers and a server are connected to a switch the server is further connected to a printer and a gateway router, which is connected via a WAN link to the Internet. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without indicating the specifics of the outside network. routers, and the style of lines between them indicates the type of connection. Readily identifiable icons are used to depict common network appliances, e.g. ![]() Computer network diagrams form an important part of network documentation.
