  4. Margaret’s Questions and Possible Answers* *answers reflecting discussion on the mailing list

  5. Question 1 • Question: • Are there any proposed solutions in this space? • Answer: • Yes, see drafts cited on agenda and presentations in second half hour. 

  6. Question 2 • Question • What is the relationship of this proposed work to similar activities in IEEE or other standards bodies? • Answer • As far as we know, there is no work in IEEE on this problem. • WiMax Forum and 3GPP have some ongoing work on mobility management in advanced cellular networks for which NETLMM could be a candidate solution. • However, neither WiMax Forum nor 3GPP has formally requested IETF to work on this problem.

  7. Question 3 • Question • How is this related to CAPWAP and/or the L2 mobility management schemes that CAPWAP is based upon?  • Answer • CAPWAP runs between a WLAN controller and access points. • Solves problem of control of access points and traffic management between access points and controller. • NETLMM runs between access routers and a mobility anchor. • Solves problem of localized mobility within a broader domain potentially covering several CAPWAP controllers. • Never sees the access points • CAPWAP and NETLMM solve two complementary but separate problems. • Most WLAN switch products today also have proprietary, non-interoperable L2-specific protocols for providing “IP mobility” (marketing speak for localized mobility management). • NETLMM would be an interoperable, L2-independent protocol available should the switch vendors choose to implement it.

  8. Question 4 • Question • The charter doesn't mention security requirements and/or have any specific deliverables related to security.  • Answer • The charter says: • Security will be defined for the protocol based on standard IETF security protocols, but should maintain configuration flexibility for varying deployment circumstances. • Is more needed?

  9. Question 5 • Question • Are there any specific drafts that are expected to become WG items? • Answer • Yes, they are: • draft-kempf-netlmm-nohost-ps-00.txt – problem statement • draft-kempf-netlmm-nohost-req-00.txt – requirements • Plan is to update drafts based on list discussion and issue WG Last Call as soon as the WG is chartered.
