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		: Benchmarking Methodology for IGP Data Plane Route 
			  Convergence
	Author(s)	: S. Poretsky, B. Imhoff

This draft describes the methodology for benchmarking IGP Route 
Convergence.  The applicability of this testing is described in 
[1] and the new terminology that it introduces is defined in [2].
Service Providers use IGP Convergence time as a key metric of 
router design and architecture.  Customers of Service Providers 
observe convergence time by packet loss.  IGP Route Convergence 
is a Direct Measure of Quality (DMOQ) when benchmarking the data 
plane and not the control plane.  The test cases in this document 
are black-box tests that emulate the network events that cause 
route convergence, as described in [1].  Black-box test design 
accounts for all of the factors for route convergence time, as
provided in [1].  The methodology and terminology is to be used 
for benchmarking route convergence and can be applied to any
link-state IGP such as ISIS [3] and OSPF [4].

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.
