net/owamp 3.1p3 OpenBSD

OWAMP is a command line client application and a policy daemon used to determine one way latencies between hosts. It is an implementation of the OWAMP protocol as defined by RFC4656.

With roundtrip-based measurements, it is hard to isolate the direction in which congestion is experienced. One-way measurements solve this problem and make the direction of congestion immediately apparent. Since traffic can be asymmetric at many sites that are primarily producers or consumers of data, this allows for more informative measurements. One-way measurements allow the user to better isolate the effects of specific parts of a network on the treatment of traffic.
