Agenda
• WG DRAFT DISCUSSIONS (ca. 1h)– Proxy Mobile IPv6 (draft-ietf-netlmm-proxymip6-11.txt)– IPv4 Support for Proxy Mobile IPv6 (draft-ietf-netlmm-pmip6-ipv4-
support-02.txt)– Interface between a Proxy MIPv6 Mobility Access 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
3
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.
4
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
• Let’s do a pragmatic discussion on what has to be done
• Let’s discuss the principles only if they have to be discussed– If we’re 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 don’t always go in parallel
• So, think around 4 (+/-1) items
13
Input from some of our friends
• 3GPP– draft-korhonen-dime-pmip6– draft-muhanna-mip6-binding-revocation– draft-muhanna-netlmm-grekey-option– draft-giaretta-netlmm-mip-interactions
• 3GPP2– Nothing outside pmip6 and IPv4 support
• Wimax Forum– ?
