Hi bmwg,

This is somewhat late for IETF 106 but I have just a few comments regarding
draft-ietf-bmwg-b2b-frame-00.  I think this draft is well written and a
valuable addition.

Best Regards,
Tim Carlin

* Section 3, item #2: re: "The Back-to-back Frame length reported for large
frame sizes..." I'm not familiar with the experiment results, but it's not
clear to me if "length" is referring to the number of frames, or the
average size of those frames, or something else.  This may just be a
misunderstanding on my part, ignore if that's the case!

* Section 3 excerpt: typo in parenthetical "cannot exceed the exceed"

>    Further, if the Throughput tests of Section 26.1 of [RFC2544] are
>    conducted as a prerequisite test, the number of frame sizes required
>    for Back-to-back Frame Benchmarking can be reduced to one or more of
>    the small frame sizes, or the results for large frame sizes can be
>    noted as invalid in the results if tested anyway (these are the frame
>    sizes for which the back-to-back frame rate cannot exceed the exceed
>    the frame header processing rate of the DUT and no buffering occurs).


* Section 4 excerpt: typo "sender and recover"

>    The Test Setup MUST be consistent with Figure 1 of [RFC2544], or
>    Figure 2 when the tester's sender and recover are different devices.
