Implementation of the One-Way Active Measurement Protocol
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 http//www.rfc-editor.org/rfc/rfc4656.txt. When referring to the protocol within this document, “OWAMP” will be in italicized. In all other instances, “OWAMP” will be referring to this implementation.
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.
