Architecture SC March May Mark Hamilton IETF/802 coordination Reviewed RFC 4441 update. Trying to balance between redundant with CBPs versus enough information here. Still open for comments – please get comments to Dorothy Stanley Also, Operations Area working group has gotten submissions on CAPWAP, and will be considering. Brief update on General Links (11ak) and 802.1 bridging discussions Most presentations will be in Thursday AM1 joint session Looks like changes are needed in 802.1AC, which will need a PAR 802 Overview and Architecture Draft 1.6 sponsor ballot Ballot deadline extended to Mar 22. Some comments addressed this week, more on telecons. Reviewed 802.11 section (Annex B.2) and comments submitted. Noted that PLCP/PMD split is being removed from 802.11, so need to describe potential changes in our architecture pictures Architecture of APs/DS/Portals, and 802.1 concepts Reviewed submission: https://mentor.ieee.org/802.11/dcn/13/11-13-0115-03-0arc-considerations-on-ap-architectural-models.doc Agreed 802.11 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 802.11 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 Three 802.11 comments needed us to do homework and submit a proposed resolution. That was done (an updated architectural picture drawn), and captured in https://mentor.ieee.org/802.11/dcn/13/11-13-0115-05-0arc-considerations-on-ap-architectural-models.doc page 15. Reviewed all 802.11 comments and their proposed resolutions. All are acceptable (with the above) Brief update on General Links (GLK SC) and 802.1 bridging discussions – Donald Eastlake Making progress and having productive discussions 802.1Qbz Draft 0.1 has been posted on the 802.1 document server Biggest challenge is understanding the architecture of AP/DS/Portal Reviewed submission: https://mentor.ieee.org/802.11/dcn/13/11-13-0115-04-0arc-considerations-on-ap-architectural-models.doc General agreement with direction headed on Figure 5-1 replacement, updates suggested.
