Hi Joseph,
Some comments:
Slide 3, last bullet: the IEEE Standard 802-2014 provides the 802 architecture for the family of 802 Stds. As it comes close to its 10-year active time cycle, a revision is required to renew it for another 10 years. There are amendments already to roll up. However, the 802 leadership is opening for comments on the revision for a better integration of different Stds, specifically between 802 Stds specified for the PHY and MAC layers with the 802 Stds operating at the MAC and above layers.
Slide 4, 4th bullet: a harmonization between 802.11 QoS mechanisms with the 802.1 traffic classification would enable a better integration with Time Sensitive Networking defined in 802.1 Stds.
Slide 4, 5th bullet: the draft revision 0.2 proposes the initial step to phase out LPD in the LLC layer. Considering the LLC specification has been unmaintained since 1998, it would be a considerable step as the use of ISO/IEC 8802-2 1998 will be redundant. Some 802.15 Stds and a mode of 802.3 already bypass the LLC layer. The operation with other 802.1 Stds is unaffected as the interfaces operate at the MAC layer. The operation of the 802.11 device above the MAC layer is unaffected as in its current form, the LLC only provides identification of the network layer and the device MAC address to the network layer. Both can be done by the EDP in the LLC or using the Ethertype value in MAC frames directly to the network layer. The draft 0.2 suggests: use the EDP in the LLC and leave the MAC layer untouched. By the way, the EDP assumes an Ethertype value field in MAC frames. That is common in 802.3 for network protocol discrimination, but I do not think it is the case for 802.11. Here, you have a topic of discussion with 802.1 Maintenance.
1 VLANS are defined in the context of the 802 architecture. In the draft revision 0.2 VLANs are mentioned as examples.
2 Modern 802 Stds do not require the LLC functionality as it was originally conceived. However, for legacy the LLC should still be part of the 802 architecture.
3 and 4 are out of scope of 802.11.
Slide 6: The revision of 802 Std is going to happen to address its end-of-life cycle, regardless of whether it is desired.
I beg to differ, the 802 Std describes the architecture of the 802 family of Stds. The term Reference Model is used instead of layers of the OSI model.
Is there an 802.11 benefit? That is not obvious to address. Although the short answer seems not: the PHY, MAC and legacy LLC layers remain the same, and what happens above the MAC layer is an afterthought. The benefit may come in the interaction with other 802.1 Stds like TSN, but certainly not from the 802 Std itself.

--- This message came from the IEEE 802.11 Working Group Reflector ---Dear All,
The ARC SC is discussing if there is an 802.11 WG need for a new Project to include a standardized 802 architecture in IEEE Std 802 for the 802 “family” of specification (802.1, 802.3, 802.11, ….).
Background and information on this possible new Project is provided in 11-22/1600r0. This new Project would likely be an 802 SC level project, managed by 802.1 (as the current maintenance project (PAR) IEEE P802-REVc – “Standard for Local and Metropolitan Area Networks: Overview and Architecture” is being managed)
The question the ARC SC is discussing is (from slide 3 of 11-22/1600r0):
Do we agree with any of these, or want to suggest another alternative?
- IEEE Std 802 should provide a standardized 802 architecture
- IEEE Std 802 should standardize a “harmonization” / “translation” for the “802 family”
- IEEE Std 802 should not provide standardized architecture
This email is intended to start an 802.11 reflector discussion, allowing for broad participation in this 802.11 WG discussion. If you have an opinion, thoughts, comments, or questions please share them on this email thread. This topic will also be discussed during the ARC SC meeting in Bangkok, Tuesday 15 November 2022 AM2 (10:30-12:30 h THA).
Regards,
Joseph Levy (InterDigital)
