Hello George, Yong and all, I only wanted to flag something in case it is important in relation to this statement. Apologies if this has been discussed or clarified already but I am a bit behind in reading the other documents. Given that we expect that the PLCA layer will need to interact with the MAC queues, then new primitives will be needed. There was a presentation by Peter Jones in this regard:
Enhanced Transmission Selection for Half-Duplex Media. Therefore, I would expect that some amount of modification to a layer above PLCA will be required to, at least, list the
new primitives. Best regards, Pablo From: George Zimmerman <george@xxxxxxxxxxxxxxxxxxxx>
Thank you Yong. I agree with your complete summary. In the presentation I presented the rationale and the 3 options for clarifying what we meant. Personally, either the option A (which Yong has below) or the option
B (including potential new non-MAC sublayers above the PHY) are fine with me - it depends on whether the group foresees anything beyond the PLCA RS, associated primitives, and potentially new primitives to a service access point - then you’d want option B).
I haven’t heard a presentation asking for this, but could envision it. I look forward to hearing from other participants. Get
Outlook for iOS From: Yong Kim <yongkim@xxxxxxxx> Dear Colleagues, Thank you George, for presenting and providing this clear summary.
For those who did not attend the ad hoc and its discussions on this please refer to the presentation link George provided. being verbose, the following changes to the PAR text will be discussed in November. Within ad hoc, there was no controversy in making this change (it's not a simple plural to singular). Original 5.2.b Scope of the project: The scope of the project is to make additions and modifications to the IEEE Std 802.3 PLCA sublayers to enhance the control of PLCA packet transmission scheduling, including management
parameters and physical layer service access points. Proposed. 5.2.b Scope of the project: The scope of the project is to make additions and modifications to the IEEE Std 802.3
Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer The proposed text has three changes. 1. editorial: spell out PLCA. Even if the first use of PLCA is spelled out on the title of the PAR, it was suggested to spell it out again ("comment magnet"), so just do it. 2. technical: PLCA sublayer, a singular, limits our work to the PLCA RS layer. No new PHY. CFI contents and all technical feasibility presentations before the Oct 1st ad hoc has been limited to changes to RS layer, There is a strong
desire to set our scope to this, and the lack of disagreement in the ad hoc supports this desire. We'll discuss this modification proposal (remove plural) in November and adopt the resulting view. 3. editorial: strike "scheduling". It is true that PLCA assists transmit scheduling in shared medium access. But it may be cause more confusion with a more commonly used upper layer function. Removing this potential comment magnet does
not change the meaning, "o enhance the control of PLCA packet transmission". Therefore we will discuss this modification proposal in November and adopt the resulting view. PLEASE this topic on this reflector, if you have concerns or alternative views. There is no reason to defer discussion till november plenary. Thank you, again George, for bring the above to our attention. best Yong. On Thu, Oct 1, 2026 at 9:29 AM George Zimmerman <george@xxxxxxxxxxxxxxxxxxxx> wrote:
