Fastrace – traceroute utility

Fastrace is a fast traceroute utility designed for network diagnostics and performance analysis.

It maps the route that packets take across an IP network from source to destination, providing detailed timing information and identifying potential bottlenecks or routing issues.

This is free and open source software.

Features include:

• Zero External Dependencies: Relies solely on standard C libraries and system calls.
• Maximum Performance: Event-driven pipeline with parallel probing and non-blocking IO.
• Low Memory Footprint: Uses compact data structures with tight allocations sized to the trace.
• Dual Socket Implementation: Uses UDP for probes and raw sockets for response capture.
• Visual Route Mapping: Displays network topology with a structured, tree-like representation.
• Runtime Tunability: Allows hop count, probe volume, concurrency, and DNS behaviour to be adjusted live.
