Abstract

With growing availability of good time sources to network nodes, it becomes increasingly possible to measure one-way IP performance metrics with high precision. To do so in an interoperable manner, a common protocol for such measurements is required. This document specifies requirements for a one-way active measurement protocol (OWAMP) standard. The protocol can measure one-way delay, as well as other unidirectional characteristics, such as one-way loss.

Abstract

   With growing availability of good time sources to network nodes, it

   becomes increasingly possible to measure one-way IP performance

   metrics with high precision.  To do so in an interoperable manner, a

   common protocol for such measurements is required.  This document

   specifies requirements for a one-way active measurement protocol

   (OWAMP) standard.  The protocol can measure one-way delay, as well as

   other unidirectional characteristics, such as one-way loss.

1.  Motivations and Goals

   The IETF IP Performance Metrics (IPPM) working group has proposed

   standards track metrics for one-way packet delay [RFC2679] and loss

   [RFC 2680] across Internet paths.  Although there are now several

   measurement platforms that implement the collection of these metrics

   ([CQOS], [BRIX], [RIPE], [SURVEYOR]), there is not currently a

   standard for interoperability.  This requirements document is aimed

   at defining a protocol that allows users to do measurements using

   devices from different vendors at both ends and get meaningful

   results.

   With the increasingly wide availability of affordable global

   positioning system (GPS) and CDMA based time sources, hosts

   increasingly have available to them time sources that allow hosts to

   time-stamp packets with accuracies substantially better than the

   delays seen on the Internet--either directly or through their

   proximity to NTP primary (stratum 1) time servers.  By standardizing

   a technique for collecting IPPM one-way active measurements, we hope

   to create an environment where these metrics may be collected across
