  1. RAMP: Reconfigurable Architecture and Mobility Platform Presenter: Shao-Hsiu Hung Date: 5th.Dec.2005

  2. Outline • Motivations • Reconfigurable Architecture and Mobility Platform • Testbed implementation and experiment results • Summary and future work

  3. Motivations • The existence of many incompatible wireless systems will last in the near future • IP mobility protocols, 3GPP, 3GPP2 • IP-based but not compatible • How to achieve universal roaming is a big challenge • A universal common core network • Reconfigurable core network • Reconfigurable mobility management – RAMP

  4. Review of IP Mobility Management • Macro-mobility • Mobile IP (MIP) • Micro-mobility • Tunnel-based • Hierarchy Mobile IP (HMIP) • Host-specific-route-based • HAWAII • Fast Link Layer Inter-domain Handoff (FLIH) – cross-layer design, distributed location tracking with broadcast-based strategy

  5. Generic IP Mobility Architecture

  6. Main Requirements of RAMP • With RAMP, both the network and the mobile node can choose their most desirable mobility management protocol • The mobile node can change its mobility protocol at anytime • Standard IP protocol and IP routing should not be changed • RAMP-unaware network nodes should continue to work with original IP protocols • Mobile nodes in the same domain can use different mobility management protocols

  7. RAMP Architecture • Components • Mobile Node (MN) – collocated with mobile host • Network Node (NN) – collocated with each router • Messages • RAMP Header + Supported Mobility Protocols + Advertisement • RAMP Header + Original Mobility Management Messages • RAMP Header

  8. Relation between RAMP and IP Protocol Stack

  9. NN Architecture

  10. MN Architecture

  11. Processing Flow (MN)

  12. Processing Flow (NN)

  13. Testbed Architecture

  14. Experiment 1: Reconfiguration

  15. Experiment 2: Co-existence MN1 MN2 MN1 (using HAWAII) MN2 (using FLIH)

  16. Summary • RAMP is a first step toward a reconfigurable core network to support the universal roaming • RAMP architecture achieves re-configurability for various mobility management protocols • RAMP architecture is realized without changing standard IP protocols and applications • RAMP-unaware nodes are not affected • A new direction for the integration of heterogeneous wireless networks

  17. Future Work • Security, QoS and other potential issues • Reconfigurable core network • Integration with cellular systems
