IETF 61 CAPWAP 11/8/2004 Meeting notes
Chairs Dorothy Gellert Mahalingam Mani Meeting start [Dorothy Gallery] Announce agenda: Going through charter IEEE AP functions ad-hoc group update - Dorothy Stanly CAPWAP taxonomy update - Lily Yang [DG] Present new charter. Local MAC and split MAC are supported by CAPWAP. CAPWAP protocols should include control plane, data forwarding, extensibility to other 802 access technology, especially 802.16. Goal for new charter: Define objectives Evaluate candidate protocols. Currently in objective draft phase. Present objective draft format and dates. Need to follow the format, currently draft does not comply with the format. WGLC - Feb. 2005 submit IEEE for review. List of milestones [Pat] What happens if the protocol is submitted and then the objective is changed because of IEEE review? [DG] Protocol will be updated based. [Hong] What if different 802 protocols have conflicting requirements? [DG] If requirement are conflicting among 802 protocols, we will focus on 802.11. [Hong] Which flavor of 802.16 will CAPWAP focus on? [DG] We should discuss this on mailing list. [Lili] CAPWAP draft update Complete security review. Address comments on security review. Concluded WG last call and address comments on v06. Changes from v4 to v5 are from security review, including 4.8.1, 4.8.3, 5.2, and section 7. Changes from v5 to v6: reorganization (introduction before definition). Clarify WTP in definition. Add more information on "client data security". Discuss PMK sharing issue- it is out of scope of the taxonomy draft. [Bernard] PMK is bound to authenticator, but not MAC address. [Roth] Propos new text for PMK sharing. If you want PMK sharing, need to know the scope of sharing. Roth sent out new text and Lily will put new text in draft and try to close it in a week. [Dorothy Stanly] 802.11 liaison report Create Ad-hoc group to describe AP functional definition. Create TGma to update AP functional definition into standard document. Details are in IEEE document 1191 and 1225 Propose to start Wireless network management study group. TGT - performance prediction. TGr - Fast BSS transition. Summary of IEEE groups. Present IEEE working group summary. [Mani] CAPWAP working group charter Aggressive schedule Initial focus on objectives - Objective is to help to create guideline for protocol selection process. Avoid orthogonal information Avoid stating the obvious - be specific. [Saravanan] presentation of draft-govindan-capwap-objectives-00.txt Comments [Interdeep] Multiple authentication methods are for user authentication. It should not be part of CAPWAP. [Saeavanan] CAPWAP needs to support multiple authentications so authentication information can be transported from WTP to AC. [Pat] Need more details on problem statement. [Lily] presentation of draft-zhou-capwap-objectives-00.txt Architecture requirement - local MAC and split MAC need to be supported. One AC needs to support both WTP architectures at the same time. Needs to define Local MAC and split MAC clearly. AC and WTP needs to be interconnected via multiple technologies - Ethernet, ATM, internal bus, etc. CAPWAP should be transparent to clients. VoWLAN is the most important service for service provider - 802.11e, fast handoff. Restrict direct inter WTP layer 2 communication- all intelligence should be sent through WTP. WLAN virtualization - allow multiple logical WLANs on single physical WLAN. Not clear if the handoff is focus on same subnet or multiple subnets. Management - WTP should be managed directly or indirectly via AC. Security - 802.11i, secure information exchange between AC and WTP. QoS - QoS policy should be supported between AC and WTP. Comments: [Interdeep] Restrict direct inter WTP layer 2 communication should be optional, not required. [Bob] Should WTP be managed directly even if AC is present? [Lily] Not clear about it. It might be needed due to the deployment rollout. [Bert]How CWPWAP affect fast-handoff? Need to focus on the right thing. [Lily] Not clearly defined in draft now. Need to go through details. [Dorothy] Need to reformat both drafts to comply with standard objective format. [Pat] There are more AC implementation details than protocols requirements in current draft. [Lily] We should clean up draft to focus on protocol requirements. [Bernard] Need to separate feature list from protocol requirement document. [Bernard] Objective should have performance requirement. [Dorothy G] open discussion Poll: Have conference call next week to have 2 draft editors to work together- approved. |
