Title : Packet Delay Variation Applicability Statement
Author(s) : A. Morton
Filename : draft-morton-ippm-delay-var-as-01.txt
Pages : 20
Date : 2006-11-29
Packet delay variation metrics appear in many different standards
documents. The metric definition in RFC 3393 has considerable
flexibility, and it allows multiple formulations of delay variation
through the specification of different packet selection functions.
Although flexibility provides wide coverage and room for new ideas,
it can be a challenge when attempting to make comparisons. Two
different formulations of delay variation have come into wide use in
the context of active measurements. This memo examines a range of
circumstances for active measurements of delay variation and their
uses, and recommends which of the two forms is best matched to
particular conditions and tasks.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
