All, There has been considerable discussion regarding jumbo frames. As a reminder to the group, the motion regarding the formation of the
SG is below: Move the IEEE 802.3 Working Group requests formation of a “Higher
Speed Study Group” to evaluate definition of greater than 10 Gb/s MAC
data rate and related PHY capability to IEEE Std 802.3. The Study Group
may recommend one or more PARs. From this motion there is nothing about studying MAC operation
in general, nothing about greater MAC efficiency or anything related to jumbos,
therefore an objective regarding jumbo frames would be out of scope. However,
as Howard alluded to, I thought it might be of potential use to let the
conversation proceed to see if something useful might come out of it. Come September we will need to hear presentations that are relevant to possible
objectives for the project. It is clear that a jumbo frame
objective would be inappropriate, but Geoff’s suggestion, which I believe
to be inline with Joel’s initial request, is potentially a useful as a
point of discussion as a possible objective – PHYs and physical layer specifications shall not be
done in any way that precludes transmission of frames up to XX Kbytes in
length. This would be within the HSSG scope. I would like to hear further
feedback on this idea, and encourage those interested in such an objective to
consider presenting material for the Study Group’s consideration. John |
