  1. Edge Mobility Protocol (EMP)(draft-wood-netlmm-emp-base-00.txt) Jonathan Wood Katsutoshi Nishida Vancouver, November 2005 IETF 64th – netlmm BOF

  2. Logical Network Architecture and Functional Entities EMD2 EMAP Edge Mobility Domain1 (EMD1) EMAP • EMAP: Edge Mobility Anchor Point • Manages MN’s location and forwards packet for MN • AAR: Advanced Access Router • Sends L3 location information to EMAP, instead of MN AAR AAR AAR AP AP AP AP MN MN MN MN Global Mobility Local Mobility Intra link Mobility Functional entities defined by EMP

  3. Scope of Edge Mobility Protocol ~ what is specified in our proposal ~ CN or GMAP • What is in scope • Basic Routing Management within the EMD • i.e. between AAR and EMAP • What is not specified • EMP Binding • Interactions between the MN and AAR • Depends on the actual link layer used Standard IP EMD or GMP EMAP EMP AAR EMP Binding* AP EMP is the protocol for AAR-EMAP routing path management MN *Triggers to initiate EMP protocol e.g. link dependent signaling, IPv6 ND signaling

  4. Characteristics of Edge MobilityProtocol • Allows the MN to keep using the same IP address within the EMD • MN IP address has the EMAP prefix • AARs advertise the same prefix owned by the EMAP • Tunnels packets from EMAP to AAR • EMAP tunnels packet to the correct AAR where MN locates • Bidirectional tunneling is also supported • EMAP manages the location of the MN by AAR

  5. Characteristics of Edge Mobility Protocol (Cont’d) • Uses the MNID for MN routing info management • EMAP and AAR manage the routing info by the MNID • MNID is not change while it is in the EMD • e.g. NAI, MIPv6 HoA • Address Management (DAD function) • EMAP manages IP addresses used in the EMD • IP version independent signaling • EMP signaling can be both IPv6/IPv4 • Also, support IPv6/IPv4 packet tunneling

  6. Protocol Overview Edge Mobility Domain EMAP 3) UPDATE (MNID, IP Addr) 4) Setup Tunnel AAR AAR 2) EMP Binding (e.g. L2 trigger) AP AP MN 1) Boot up

  7. Protocol Overview Edge Mobility Domain 3) Query (MNID, IP Addr) EMAP AAR AAR 4) Tunnel Switch 2) EMP Binding (e.g. L2 trigger) AP AP MN MN 1) Handover

  8. Use Case of NETLMM Protocol Operator Core Network EMAP NETLMM Protocol … … … … WLAN Access New Radio /Fix Accesses 3G UMTS (UTRAN) 3G Evolved UTRAN AP AP AP AP Evolved NodeB Evolved NodeB NodeB NodeB MN MN Radio dependent Mobility Management Operators can benefit from NETLMM Protocol since it provides IP Mobility meeting requirements
