    <section title="Introduction">
      <t>The Large-scale Measurement of Broadband Performance (LMAP) working
      group has completed a Framework <xref target="RFC7594"/> and Use cases,
      and now proceeds with development of an information model <xref
      target="I-D.ietf-lmap-information-model"/> and data model.</t>

      <t>The IETF IP Performance Metrics (IPPM) working group first created a
      framework for metric development in <xref target="RFC2330"/>. This
      framework has largely stood the test of time and enabled development of
      many fundamental metrics. It has been updated once in the area of metric
      composition <xref target="RFC5835"/>, and again in several areas related
      to active stream measurement of modern networks with reactive
      propoerties <xref target="RFC7312"/>. The Working Group has developed an
      extensive set of Standards Track Metrics and Measurment Protocols. Among
      the work especially relevant to LMAP is the development of a Performance
      Metrics Registry <xref target="I-D.ietf-ippm-metric-registry"/>, and a
      proposal for the initial regsitry contents <xref
      target="I-D.morton-ippm-initial-registry"/>.</t>

      <t>This memo is orgainzed into sections that present an example of LMAP
      Control and Reporting by populating the various information model
      objects for measurement Tasks and Reporting Tasks (and eventually
      Schedule, Event, Action, etc).</t>

      <t>The first example is a UDP Round Trip Latency Metric.</t>
    </section>

    <section title="Scope and Purpose">
      <t>The purpose of this memo is to examine the features and capabilities
      of the LMAP information model <xref
      target="I-D.ietf-lmap-information-model"/> by populating the models with
      example data intended to enable measurement of IPPM metrics.</t>

      <t>The scope is to create the examples for Active Metrics and their
      Methods of Measurement, as defined in the IPPM literature of Standards
      Track Metrics. Specifically, Metrics in the proposed initial contents
      for the Performance Metrics Registry <xref
      target="I-D.ietf-ippm-metric-registry"/> contined in <xref
      target="I-D.ietf-ippm-metric-registry"/> are the primary focus, along
      with existing standards track measurement protocols developed in IPPM
      <xref target="RFC4656"/> <xref target="RFC5357"/>.</t>

    <section title="UDP Round Trip Latency">
      <t>This draft presents information in a conceptual form. Safeguarding
      correct syntax is a collosal non-goal in the early drafts.</t>

      <t>The security considerations that apply to any active measurement of
      live paths are relevant here as well. See <xref target="RFC4656"/> and

      <t>When considering privacy of those involved in measurement or those
      whose traffic is measured, the sensitive information available to
      potential observers is greatly reduced when using active techniques
      which are within this scope of work. Passive observations of user
      traffic for measurement purposes raise many privacy issues. We refer the
      reader to the privacy considerations described in the Large Scale
      Measurement of Broadband Performance (LMAP) Framework <xref
