Some comments addressed this week, more on telecons. Reviewed section (Annex B.2) and comments submitted. Noted that PLCP/PMD split is being removed from , so need to describe potential changes in our architecture pictures –Architecture of APs/DS/Portals, and concepts Reviewed submission: Agreed Figure 5-1 (MAC data plane architecture) has issues and confusing parts. Started work toward a proposed replacement. Need to get clarification on all (architectural) interface points within specification – all MAC-SAPs (are there more than one?), etc. May –IETF/802 coordination – Dorothy Stanley Update on joint activities between IETF and IEEE 802 Reviewed RFC 4441 update (rev4). One comment proposed, Dorothy will carry to editing committee –802 Overview and Architecture Draft 1.6 sponsor ballot Three comments needed us to do homework and submit a proposed resolution. That was done (an updated architectural picture drawn), and captured in models.doc page 15. models.doc Reviewed all comments and their proposed resolutions. All are acceptable (with the above) –Brief update on General Links (GLK SC) and bridging discussions – Donald Eastlake Making progress and having productive discussions 802.1Qbz Draft 0.1 has been posted on the document server Biggest challenge is understanding the architecture of AP/DS/Portal –Architecture of APs/DS/Portals, and concepts Reviewed submission: General agreement with direction headed on Figure 5-1 replacement, updates suggested.
