Examples of LMAP Objects using IPPM Metrics and Protocols
draft-morton-lmap-examples-01
Abstract
In order to examine the completeness and coverage of the LMAP info
and data models, we present examples expressing information from IP
Performance Metric working group metrics and protocols, and the
Performance Metrics Registry. The main update in the version
provides a more realistic and useful example of the Cycle_ID in
measurement instruction and reporting.

1. Introduction
The Large-scale Measurement of Broadband Performance (LMAP) working
group has completed a Framework [RFC7594] and Use cases, and now
proceeds with development of an information model
[I-D.ietf-lmap-information-model] and data model.
The IETF IP Performance Metrics (IPPM) working group first created a
framework for metric development in [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 [RFC5835], and again in several areas related to active
stream measurement of modern networks with reactive propoerties
[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 [I-D.ietf-ippm-metric-registry], and a proposal for
the initial regsitry contents [I-D.morton-ippm-initial-registry].
This memo is orgainzed into sections that present an example of LMAP
Control and Reporting by populating the various information model
Morton Expires September 22, 2016 [Page 2]
Internet-Draft LMAP Examples of IPPM March 2016
objects for measurement Tasks and Reporting Tasks (and eventually
Schedule, Event, Action, etc).
The first example is a UDP Round Trip Latency Metric.
2. Scope and Purpose
The purpose of this memo is to examine the features and capabilities
of the LMAP information model [I-D.ietf-lmap-information-model] by
populating the models with example data intended to enable
measurement of IPPM metrics.
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
[I-D.ietf-ippm-metric-registry] contined in
[I-D.ietf-ippm-metric-registry] are the primary focus, along with
existing standards track measurement protocols developed in IPPM
[RFC4656] [RFC5357].
3. UDP Round Trip Latency
This draft presents information in a conceptual form. Safeguarding
correct syntax is a collosal non-goal in the early drafts.

4. Security Considerations
The security considerations that apply to any active measurement of
live paths are relevant here as well. See [RFC4656] and [RFC5357].
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 [RFC7594],
which covers active and passive techniques.
5. IANA Considerations
This memo makes no requests of IANA.
