[802.3ae] Proving PMD feasibility
Bob,
Recently, I saw your concern echoed by others as well. Clearly, the
PMD community needs to sit up and address it. Yes, the 10G PMD
feasibility can be demonstrated, although I am afraid it's a little
late to organize this effort in a week. Yes, there is enough time to
do it by September.
It's important that we begin by defining expectations. What does a
"feasibility demonstration" mean to you at this stage?
At this stage, a schedule-friendly answer would be "showing test
results of a 10.3G link operating over the required distance,
showing a reasonable agreement between the link model and
measurements, and showing analysis to suggest that high yield and
low cost are likely to be achieved".
A schedule-unfriendly answer would be "showing full compliance and
interoperability".
