  1. DMM Approaches with Functional Decomposition WEN LUO IETF#85 Atlanta, Nov.2012

  2. Functional Decomposition • Share similar view with draft-chan-dmm-framework-gap-analysis • Basic Functional Elements • MR (Mobility Router) : First hop router • LM (Location Management) • HAA (Home Address Allocation) • MRs are deployed in a distributed manner • LM/HAA could be deployed in centric manner or deployed as distributed database

  3. Example of Networking Model • A dmm administrative domain consists of multiple Local Networks • Each Local Network • Includes one or multiple MRs • Includes one HAA and at least one LM • Create Interface among LMs within this domain

  4. Concept Architecture • Home Local Network: the local network in which the MN performs initial attachment and be assign with IP prefix/address • Visited Local Network: the local network the MN is current attached to

  5. Optimized Routing Setup Scenario 1 • Buffering first few packets

  6. Optimized Routing Setup Scenario 2 • Transfer first few packets to MR which assigns IP prefix/address to the MN in its home network
