[HSSG] Jumbo Frame Discussion


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.
