Examples of LMAP Objects using IPPM
Metrics and ProtocolsAT&T Labs200 Laurel Avenue SouthMiddletownNJ07748USA+1 732 420 1571+1 732 368 1192acmorton@att.comhttp://home.comcast.net/~acmacm/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.The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119.The Large-scale Measurement of Broadband Performance (LMAP) working
group has completed a Framework and Use cases,
and now proceeds with development of an information model and data model.The IETF IP Performance Metrics (IPPM) working group first created a
framework for metric development in . 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 , and again in several areas related
to active stream measurement of modern networks with reactive
propoerties . 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 , and a
proposal for the initial regsitry contents .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).The first example is a UDP Round Trip Latency Metric.The purpose of this memo is to examine the features and capabilities
of the 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 contined in are the primary focus, along
with existing standards track measurement protocols developed in IPPM
.This draft presents information in a conceptual form. Safeguarding
correct syntax is a collosal non-goal in the early drafts.TBDThe security considerations that apply to any active measurement of
live paths are relevant here as well. See and
.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 , which covers active and passive techniques.This memo makes no requests of IANA.The author thanks LMAP Participants for their comments.The Illusion of Being Deterministic – Application-Level
