Russ, As interesting as this paper is, I always found it to be a tough fit for the BMWG. This proposed work item has no related terminology or methodology draft. The tests are not clearly described in the paper and refer to the need to simulate hundreds of nodes for a lab benchmark test. I went through the thread from last April '04 (6 months ago) and read numerous responses in objection to this becoming a work item. My mind is open to be changed so can you please clearly explain what is being benchmarked, how it is being benchmarked, and why you think this is appropriate for the BMWG.

Berkowitz; bmwg@ietf.org Subject: RE: [bmwg] Is the BMWG a proper home for this I-D?ch Okay, it's been a couple of months since we've talked about this.... Have we reached any concensus on it? If BMWG isn't going to take it on, I need to get with the ADs and see what can be done about pushing it as an individual contribution (though I still think it's more benchmarking related than real world testing, after re-reading it). If anyone would like to contribute more considerations, to make the draft "wider," those would be welcome, too. :-) Russ On Wed, 7 Apr 2004, Jim McQuaid wrote: > You make an excellent point (can it be tested with created traffic or does > it require live network traffic in some form).
