IEEE Std. 802.11-22/1017r0 Overview and Architecture Presentation

This presentation by Dorothy Stanley from HP Enterprise delves into the utilization of IEEE Std. 802.11-2020 standards focusing on the IEEE Std. 802 overview and architecture. It covers topics such as the use of LLC, MAC address formats, QoS mechanisms, MSDU formats, and various MAC services and protocols related to the IEEE 802.11 standard. The document also highlights the support for Quality of Service via User Priority, discussing different QoS management mechanisms specified in the standard, including EDCA Access Categories, Traffic Classification, and Mirrored Stream Classification Service.

1. July 2022 doc.: IEEE 802.11-22/1017r0 802.11 standard use of 802 architecture Date: 2022-07-11 Authors: Name Dorothy Stanley Affiliations HP Enterprise Address Phone +1 630-363-1389 email dorothy.stanley@hpe.com Submission Slide 1 Dorothy Stanley (HP Enterprise)

2. July 2022 doc.: IEEE 802.11-22/1017r0 Abstract This presentation summarizes IEEE Std 802.11 -2020 use of the IEEE Std 802 Overview and Architecture, for discussion at the 2022-07-11 802 Technical Plenary Tutorial meeting. Use of the LLC, MAC address formats, QOS mechanisms and MSDU formats are described. Extracted text is from IEEE Std 802.11 -2020 Submission Slide 2 Dorothy Stanley (HP Enterprise)

3. July 2022 doc.: IEEE 802.11-22/1017r0 802.11 MAC Services supportLLC sublayer entities LLC sublayer entities or IEEE 802.1Q bridge ports can use the 802.11 service to exchange MAC Service Data Units (MSDUs) Submission Slide 3 Dorothy Stanley (HP Enterprise)

4. July 2022 doc.: IEEE 802.11-22/1017r0 All 802.11 MAC Services and protocols use 48-bit MAC addresses 48 bit MAC addresses are used (See 9.2.2) Submission Slide 4 Dorothy Stanley (HP Enterprise)

5. July 2022 doc.: IEEE 802.11-22/1017r0 Quality of Service via User Priority is supported While the reference to 802.1D is being removed, the functionality remains Submission Slide 5 Dorothy Stanley (HP Enterprise)

6. doc.: IEEE 802.11-22/1017r0 Several QoS management mechanisms are specified in the 802.11-2020 standard Including: 802.11e EDCA Access Categories: Voice, Video, Best Effort, Background; widely implemented as WFA WMM Stream Classification Service (initial specification dates to 2009) Traffic Classification (TCLAS) based on L3 parameters (IPsec Security Parameter Index ) and MAC layer parameters Use Multiple TCLAS elements to define SPI, IP Address, Ports Mirrored Stream Classification Service: Client devices direct the AP QoS marking of downlink IP flows (useful when DSCP markings not present) QoS MAP feature: L2 priority based on L3 DSCP marking in IP headers * Many of these mechanisms have WFA interoperability certification.

7. July 2022 doc.: IEEE 802.11-22/1017r0 Both Logical Link Control (LLC) Protocol Discrimination (LDP) and Ethertype Protocol Discrimination (EPD) are supported LDP is generally used; EDP used in: 802.11p/bd (Vehicular) 802.11ak (General Links) for 802.1Q bridge port links Submission Slide 7 Dorothy Stanley (HP Enterprise)

8. July 2022 doc.: IEEE 802.11-22/1017r0 Figure 5-1 shows the MAC Data Plane architecture, including use of 802 entities, including 802.1X Submission Slide 8 Dorothy Stanley (HP Enterprise)

9. July 2022 doc.: IEEE 802.11-22/1017r0 Summary: The 802.11 standards uses several components of the 802 architecture Use of the LLC, MAC address formats, MSDU formats: enable straightforward implementation of devices with Ethernet and IETF IP based protocols QOS mechanisms are based on defined UPs The 802.1X Security framework is used, enabling use of IETF EAP protocols and multiple credential types 802.11 uses the 802.1AC definitions of the MAC Service, enabling use of other 802.1-defined facilities, in addition to providing the expected and standardized MAC SAP interface Submission Slide 9 Dorothy Stanley (HP Enterprise)
