Network map

A network map shows physical and/or logical network configurations, including information about hierarchies of connectivity (e.g., a main network and its subnetworks). Network maps are constructed using information either supplied by a human or obtained through automated discovery. Topological or logical network information can be displayed alone or superimposed on a geographical map. Network mapping can also include the automated processing and analysis of network traffic and topology data for presentation using network visualization tools.

Network mapping is essential to network engineering, monitoring, maintenance, and repair. Network size and complexity require that analysts be able to quickly visualize congestion points using near real-time traffic data. By graphically monitoring large networks and detecting when link utilization is growing faster than expected, it may be possible to quickly determine if the network is experiencing a physical disruption or a cyber attack. Network mapping is also used in research on network performance.
