A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Benchmarking Methodology Working Group of the IETF.

	Title		: Hash and Stuffing: Overlooked Factors in Network Device Benchmarking

Test engineers take pains to declare all factors that affect a given
   measurement, including intended load, packet length, test duration,
   and traffic orientation.  However, current benchmarking practice
   overlooks two factors that have a profound impact on test results.
   First, existing methodologies do not require the reporting of
   addresses or other test traffic contents, even though these fields
   can affect test results.  Second, "stuff" bits and bytes inserted in
   test traffic by some link-layer technologies add significant and
   variable overhead, which in turn affects test results.  This document
   describes the effects of these factors; recommends guidelines for
   test traffic contents; and offers formulas for determining the
   probability of bit- and byte-stuffing in test traffic.

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
