Definition Edit

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.[1]

Overview Edit

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.
