During today’s ad hoc we discussed the meaning of “PLCA Sublayers” (plural) in the PAR scope. At the Lisbon interim, the study group approved text for a draft PAR scope as motion #1 using this term. A presentation highlighted that there is only one sublayer known as “PLCA” in the existing 802.3 standard,
and it was unclear what the plural term meant – presenting 3 options (an error – which had been discussed in Lisbon, a meaning for other non-MAC client or control sublayers, or a meaning including PHY sublayers, for example the PCS). If the meaning were to
include layers below the RS (such as the PHY PCS), then the PAR scope should make it clear to those outside of our group that we are considering modifying those within the scope of the project – and not just PLCA. See
https://www.ieee802.org/3/EPLCA/public/261001/zimmerman_EPLCA_01_20261001.pdf for details as other suggested, purely editorial, changes to make the PAR scope clear. Because the 1 October meeting was an ad hoc, no consensus decision could be taken, but during discussion, there was general sentiment expressed by some individuals that the project could be accomplished with
only modifications to the PLCA reconciliation sublayer. As a result, some participants suggested changing “PLCA Sublayers” to “Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer” would be a reasonable solution. The study group will have an opportunity to modify the PAR scope text at the plenary meeting in November (which is normal, at least to make adjustments to respond to comments from other 802 working groups).
Further, it was discussed that changes to the PAR scope such as to clarify this issue should not impact presubmission. In order to build consensus prior to the November meeting, the study group Chair Pro Tem as me to initiate discussion of the issue on the reflector. Please feel free to respond with your preference for the project scope and explanation so that we can discuss further and hopefully build consensus prior to November.
