k – Radio Resource Measurement Measurements provided for runtime adjustment of radios Available to internal STA components, higher layers, and external devices m – Maintenance (compilation of all approved amendments) IEEE Std approved by SASB March 8, 2007 New mb Maintenance Task Group was started in this (March 2007) meeting r – Fast BSS Transition Between BSSes within the same ESS Relies on k (especially neighbor reports) u – Interworking with External Networks MAC changes to accommodate, among others, Relies on k and r; has scope agreement with v v – Wireless Network Management Management protocol additions; AP-AP negotiations; load balancing; access controls New Chair of the group TG is recommending Dorothy Stanley to the WG; WG will decide tomorrow w – Protecting Management Frames Security for management frames, including broadcast frames Relies on k, r and perhaps u aa (??) – New DLS May be approved by IEEE 802 EC tomorrow Groups Related to (more than the usual suspects)

aa(??) New DLS New Proposed Task Group DLS: Direct Link Setup Direct communications between two non-AP STAs Problem with Current DLS Definition Must be set up by communications with the AP Requires AP specifically to be capable of supporting this Not many APs today have this capability Want a DLS that can be set up between STAs without a special AP In addition, current DLS definition does not support Power Save Proposed TG A couple of groups have clear ideas (and trials) of how to accomplish this – ndls.ppt – wng-flexwifi-distributed-dls.ppt Proposed PAR and 5C draft-par-and-5-criteria-dls-sg.doc Likely approval by WG Tomorrow Morning May be approved by 802 WG EC Tomorrow Afternoon

u Highlights (Quick Summary, since has great interaction with 11u) Summary of February Ad-Hoc with : Motions summary; Motions for new text passed (available after this meeting) – MIME Corrections: 8:0: – GAS Comment Resolutions: 9:0: – SSPN Interface: 10:0: – QoS Map Interworking: 10:0: – GAS MIB: 12:0: – ES Capability IE: 12:0: – ES Alert Notification: 12:0: – Intro Text for Clause 5: 13:0: (see also ) – Multi-SSID (mSSID): 24:0: – Rewrite of QoS Mapping Sections: 15:0: / – ES Public Credentials / Usage: 17:0: – SSPN Admission Control: 14:0:9 New development material – looking for additional inputs – Using for Emergency Services – HotSpot Identification (search, sort, categories) One presentation remaining this afternoon Timeline:  will become an document Current Draft: D comments from Draft 0.02; still filling in blank spots in text But a LOT of changes in this session *Might* go to Letter Ballot in May 2007

r Letter Ballot Status Latest re-circulation ballot comments completed Current Draft 4.3 was available this morning Authorized re-circulation ballot on Draft 5.0 (same as 4.3) Finished all comments this week Complete comment resolutions: r-d4-comments.xls Deciding on another recirculation ballot late today 15-day, so will be complete in early April Ad-hoc April 24-26, Arlington, VA for comment resolution Scheduled also a backup ad-hoc June in Toronto

r This Session, 1 Controversy #1 Ruling by the TGr Chair In November a motion to make a group of key distribution changes was first defeated, then, with a text change, successful For the ruling controversy, compare and , then see documents: – r-response-to-ieee appeal-december-5 th doc – r-chair-ruling doc March session: –Special board appointed by Chair upheld the ruling of the TGr Chair –Judgment: appeal-panel-decision.pdf So the “Push Model” is now in place Reference: r-key-distribution-push- capability.doc – but see final version in Draft 4.3

r This Session, 2 Controversy #2 Architecture of non-AP STA Does it need to have the same logical security blocks as the AP? Some argue that symmetry between AP and non-AP is required for security. Still an issue So far symmetry has been retained Symmetry likely to be retained as long as gain from asymmetry is minor

r This Session, 3 Controversy #3 Abandonment of non-CCMP security Early this week the TG voted not to support TKIP in Fast Transitions –TKIP is still allowed in –The decision was just not to support it in r –A vendor may still extend r to cover TKIP But wording of the text now says: must support CCMP Proposal to allow old wording Supporting TKIP, but also other security systems Debate over whether this proposal was complete Vote: 9:7:7 (failed) Issue will definitely come back next meeting Proposers need to create motion with text changes throughout the Draft that say “CCMP or better security”

r Timeline PAR was approved over 2 years ago Note: External Security Review is starting now Over 20 experts involved Circulations Still possible to go to Sponsor Ballot after July, 2007 Plenary Limitations IETF support : Key Management 11r is putting very specific requirements on key management Correction: IETF is not working on this; decision is to be vendor-specific k dependencies If k doesn’t finish first, arrangement is to copy the portions of k that r needs Key point: So r sponsor ballot still before sponsor ballot
