yaNetCheck

Checking a network path with a stream of UDP datagrams: losses, duplicates, reordering.

Version	X.01-28ECO01 (per the archive; the README says X.01-02)
Status	Maintained
Platforms	Linux (glibc), x86_64 and aarch64
Licence	Apache License 2.0
For whom	Those who check a line, a switch, a router or a whole path at a given packet rate.

What it is

The sender sends UDP datagrams (or raw frames through AF_PACKET) with increasing numbers; the receiver counts losses, duplicates and reordering. It helps to tell "the packets do not reach the wire" from "they reach the interface but a local firewall drops them". It prints periodic statistics and survives a restart of either side.

Why

Long checks before and after a change of the network.
