udp-echost2.0.0

udp-echost measures the round-trip behavior of UDP traffic between a client and an echo server, exposing latency patterns that a simple reachability check can miss. Start the server with udp-echost -s -p 50505, then point a client at that port with udp-echost -c -p 50505 to run a test. The client can send a fixed packet count, operate for a chosen duration, or continue in continuous mode.

Results include round-trip time, packet loss, packet reordering, and jitter calculated in the style of RFC 3550. It also reports P50, P95, and P99 latency percentiles so you can see typical performance alongside higher-latency cases. A configurable payload size lets you test packets resembling the traffic produced by the application being investigated.

This makes udp-echost useful for diagnosing UDP behavior in VoIP, online gaming, and custom UDP protocols, where latency distribution matters more than raw throughput alone. Its focus on UDP round-trip statistics distinguishes it from ICMP-only reachability probes and throughput-oriented network tests. Network engineers, developers, and operators can use it to examine how a path handles the packet sizes and traffic patterns relevant to their services.

Version 2.0.0 is a single-binary Linux program for x86_64 (amd64) systems and requires snapd. It is open-source software published by Aswin Kumar K.
