Description of Working Group:

  The IP Performance Measurement (IPPM) Working Group develops and maintains
  standard metrics that can be applied to the quality, performance, and
  reliability of Internet data delivery services and applications running over
  transport layer protocols (e.g. TCP, UDP) over IP. It also develops and
  maintains methodologies and protocols for the measurement of these metrics.
  These metrics, protocols, and methodologies are designed such that they can be
  used by network operators, end users, or independent testing groups. Metrics
  developed by the IPPM WG are intended to provide unbiased quantitative
  performance measurements.

  The IPPM WG works to foster commonality and comparability of metrics and
  measurements across IETF protocols at different layers. Its work is limited to
  metrics and methodologies which are applicable over transport-layer protocols
  over IP, and does not specify encapsulations required for measurements over
  non-IP layers.

  The IPPM WG has produced documents that define specific metrics and procedures
  for accurately measuring and documenting these metrics. The working group will
  continue advancing the most useful of these metrics along the standards track,
  using the guidelines stated in RFC 6576. To the extent possible, these metrics
  will be used as the basis for future work on metrics in the WG.

  The WG will seek to develop new metrics and models to accurately characterize
  the network paths under test and/or the performance of transport and application
  layer protocols on these paths. The WG will balance the need for new metrics
  with the desire to minimize the introduction of new metrics, and will require
  that new metric definitions state how the definition improves on an existing
  metric definition, or assesses a property of network performance not previously
  covered by a defined metric. Metric definitions will follow the template given
  in RFC 6390.

  Additional methods will be defined for the composition and calibration of
  IPPM-defined metrics, as well as active, passive and hybrid measurement methods
  for these metrics. In addition, the WG encourages work which describes the
  applicability of metrics and measurement methods, especially to improve
  understanding of the tradeoffs involved among active, passive, and hybrid

  The WG may update its core framework RFC 2330 as necessary to accommodate these activities.

  The WG has produced protocols for communication among test equipment to enable
  the measurement of the one- and two-way metrics (OWAMP and TWAMP respectively).
  These protocols will be advanced along the standards track. The work of the WG
  will take into account the suitability of measurements for automation, in order
  to support large-scale measurement efforts. This may result in further
  developments in protocols such as OWAMP and TWAMP.

  Agreement about the definitions of metrics and methods of measurement enables
  accurate, reproducible, and equivalent results across different implementations.
  To this end, the WG defines and maintains a registry of metric definitions.

  The WG encourages work which assesses the comparability of measurements of IPPM
  metrics with metrics developed elsewhere. The WG also encourages work which
  improves the availability of information about the context in which measurements
  were taken, for example (but not limited to) measurement implementation
  information, estimates of confidence in these measurements, conditions on the
  network(s) on which measurements are taken, and/or information about the
  data-plane topology of these network(s).

  In the interest of measurement comparability, the WG may define data formats and
  information models for the storage and exchange of the results of measurements
  defined within IPPM.

  The IPPM WG seeks cooperation with other appropriate standards bodies and forums
  to promote consistent approaches and metrics. Within the IETF process, IPPM
  metric definitions and measurement protocols will be subject to as rigorous a
  scrutiny for usefulness, clarity, and accuracy as other protocol standards. The
  IPPM WG will interact with other areas of IETF activity whose scope intersects
  with the requirement of these specific metrics. The WG will, on request, provide
  input to other IETF working groups on the use and implementation of these
