Title : A Framework for Internet Traffic Engineering
Measurement

In this document, a measurement framework for supporting the traffic
engineering of IP-based networks is presented. Uses of traffic
measurement in service provider environments are described, and
issues related to time scale and read-out period are discussed.
Different measurement types are classified, with each being
specified as a meaningful combination of a measurement entity and a
measurement basis.
For interoperable compatibility, uniform definitions across vendors
and operators must be ensured, e.g., in the distinction between
offered load and achieved throughput. To aid network dimensioning,
mechanisms to collect node-pair-based traffic data should be
developed to facilitate the derivation of per-service-class traffic
matrix statistics. For service assurance, there is a need for the
use of higher-order statistics. To preserve representative traffic
detail at manageable sample volumes, there is a need for packet-
sampled measurements. To manage large volume of measured data, use
of bulk transfer and filtering/aggregation mechanisms may be
appropriate.

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
Internet-Draft.
