  Gateway and a Mobile Node (draft-ietf-netlmm-mn-ar
  -if-03.txt)
• RECHARTERING
• The priorities for the next 12 months
• Discussion on what items have to be done first
• Other rechartering considerations
• NEXT STEPS and WRAP UP

Rechartering Discussions

• Discuss charter principles that need any updates
• Decide on the work items to be taken up for the
  next 12 months
• Discuss scope of each item to be included and
  explicitly decide what is in and out of scope
• Discuss items that may need to be dealt with
  outside the WG
• e.g., SDO-specific informational documents
• Work in other WGs with cross review by NETLMM,
  etc.

Focusing the discussion

• We are discussing about timing
• We are not discussing if a single work item is
  important or not
• Assume all items to be important
• Concentrate on the question What has to be done
  first?

5
Charter Principles A Recap

• Local mobility management protocol that does not
  involve changing the MN
• LMM protocols that affect the MN have already
  been defined
• Independent of global mobility management
  protocols
• Can be layered under any GMM protocol
• Link layer agnostic
• General IETF philosophy
• Protocol can be used over heterogeneous link
  layers
• Link layer specific handover indications may be
  used
• Not designed for inter-interface handover on MNs
• Such handoffs not involving the IP stack on MNs
  is not within IETF scope (can already be handled
  with the base protocol)
• Affecting the MN IP stack is a specific non-goal
• IETF has developed other mobility protocols with
  MN involvement

6
Question on Principles

• Lets do a pragmatic discussion on what has to be
  done
• Lets discuss the principles only if they have to
  be discussed
• If were about to take a work item that calls for
  principle discussion

7
Candidates for the New Charter (1/5)

• LMA Discovery
• Dynamic discovery of a suitable LMA for an MN
• Multiple LMA connectivity from a MAG
• AAA extensions
• MAG-AAA and LMA-AAA interfaces
• RADIUS and Diameter support to
• Allow MAG/LMA to obtain the MN policy profile
• AAA server may provide configuration information
  such as the home network prefix, etc.
• Set up a mutually authenticated channel between
  MAG and LMA

8
Candidates for the New Charter (2/5)

• GRE Extensions to PMIPv6
• Enable MNs from overlapping IPv4 address spaces
  to coexist under a given LMA
• Binding Revocation
• LMA initiated revocation of PMIP binding to
  cleanup MAG state and force detachment of MN
• MAG-LMA Heartbeats
• Keepalive messages to detect failure at either end

9
Candidates for the New Charter (3/5)

• Interactions with MIP6
• Scenario A PMIP6 as local mobility protocol
  MIP6 as global mobility protocol (hierarchical
  system)
• Scenario B Supporting MIP6 and PMIP6 in the same
  domain
• Scenario C PMIP6 support on MIP6 home link
  (extending the MIP6 home link to have the HoA be
  the PMIP6 IP address of the MN)
• Interactions with MIP4
• Transitions between PMIP6 and MIP4
• Handling MIP4 FAs with MAGs and ARs

10
Candidates for the New Charter (4/5)

• Multihoming
• Multihoming scenarios
• Supporting multiple interfaces with PMIP6
• Handovers across various interfaces
• Handover optimizations
• FMIP support for PMIP6 (taken up by MIPSHOP?)
• Context transfer between MAGs (taken up by
  MIPSHOP?)
• Forwarding ingress traffic from a different MAG
• Relation to multiple CoA registrations?
• Transient CoA or secondary binding
• Inter-technology handoffs using PMIP6

11
Candidates for the New Charter (5/5)

• NEMO and PMIP6
• Supporting a prefix on the ingress interface of
  the MN
• Re-use of the PMIP6 prefix on the egress
  interface of the MN vs. new ingress prefix
• Route optimization for PMIP6
• Intra-MAG RO
• Inter-MAG, intra-LMA RO
• Inter-LMA RO

12
OK, what should be done first?

• Pick work for the next 12 months
• Please, be realistic
• We are not going to get 20 items in a year
• Things dont always go in parallel
• So, think around 4 (/-1) items
