Network Map Definition

From the English network map. A network map is a graphical representation of all the computers and devices on a network that shows how they are connected to each other. It can also be used to quickly access any element of the network quickly.

Network map concept

A network map is a visualization of the devices on a network, their interrelationships, and the transport layers that provide network services.

In practice, a Network Map is a tool to provide network users, managers and administrators, and Information Technology personnel with a better understanding of network performance, especially as it relates to network necks. data bottle analysis and associated root cause analysis.

network mapping

Network mapping is the study of the physical connectivity of networks, for example, the Internet. Network mapping discovers network devices and their connectivity. Not to be confused with network discovery or network enumeration which detects devices on the network and their characteristics (operating system, open ports, listening network services, etc.). The field of automated network mapping has grown in importance as networks become more dynamic and complex.

Techniques for producing a network map

Three techniques for producing a Network Map include: SNMP-based approaches, active probing, and route analysis.

SNMP-based maps: These obtain data from router and switch MIBs (management information bases), which are hierarchical virtual databases of a network (or other entity).

Active probing: These maps are created with data from a series of «traceroute-like probe packets», that is, special data packets or frames, which report on the router’s IP and change forwarding paths to the router’s IP address. of destiny. By collecting this data that describes the actual transmission paths of data through networks, network maps are created and used to find «peering links» between ISPs (Internet Service Providers); These are links (physical lines or channels) that connect different networks that are part of the Internet and that allow ISPs to exchange customer traffic for mutual benefit.

Route Analysis: This approach uses routing protocol data to create a network map by passively listening for Layer 3 protocol exchanges between routers. This data facilitates network discovery, real-time network monitoring and routing diagnostics, as well as network mapping.

internet mapping techniques

Two techniques are most prominent in use today to create maps of the Internet. The first works on the Internet data plane and is called active probing. It is used to infer the topology of the Internet based on router adjacencies.

The second works in the control plane and infers the connectivity of an autonomous system based on BGP data. A BGP speaker sends 19-byte keep-alive messages every 60 seconds to maintain the connection.
