Toplanmtr

Toplanmtr is a term used in information technology to describe an integrated approach or toolset that combines topology planning with traceroute-based measurements (MTR). The term is not standardized and typically appears in informal discussions and some open-source projects. It is used to denote workflows or software that aim to map and monitor a network's topology while assessing path performance.

Etymology and scope: Toplanmtr is generally treated as a portmanteau of topology and MTR (the combined traceroute tool). In practice, it can refer to methods that couple topology discovery (via LLDP/CDP, SNMP, or active probing) with path tracing data to produce a live topology map annotated with latency and packet loss. Variants of the concept may emphasize different aspects, such as LAN planning, regional network mapping, or real-time path analytics.

Functionality: A typical top-lan-mtr workflow collects device topology information, runs MTR or traceroute across routes of interest, and integrates results into a visual or data-oriented topology model. Outputs may include hop-level latency, jitter, loss, and hop identity, enabling quick identification of bottlenecks or misrouted links.

Applications and limitations: Useful for network diagnostics, capacity planning, and post-incident analysis. It is not a formal standard; implementations vary. Limitations include firewall policies that block probes, data accuracy dependent on device visibility, and potential network disruption from active probing.
