9. Problems of Current Internet Overloaded semantics of IP address Identifier and Locator as well Single protocol for heterogeneous networks No consideration of heterogeneous networks Integration of data delivery and control function No distinction between data plane and control plane Centralized mobility control Home Agent (central anchor) of Mobile IP Traffic overhead, failure by DoS attack, non-optimal routes Geneva, Switzerland, 11 June 20129

10. Architectural Requirements for FN Separation of identifier (ID) and locator (LOC) Permanent ID and Temporary LOC (Mobility, Multi-homing) Separation of access/backbone networks Support of Heterogeneous access networks Separation of control plane from data plane Control (mobility) information: mission-critical User data packets: best-effort Distributed mobility control Built-in mobility control (cf. MIP: patch-on) Use of Optimized Route (Query-based signaling) Scalable management of ID-LOC mappings Geneva, Switzerland, 11 June 201210

11. Functional Requirements for FN Location management ID-LOC mapping management for mobile hosts ID-LOC Binding and Query Operations Route optimization Direct (Optimized) path between two communicating hosts Handover control Seamless handover for on-going sessions Route Update Geneva, Switzerland, 11 June 201211

15. Problems vs. Design Principles Geneva, Switzerland, 11 June 201215 Current Internet MOFI Design PrinciplesFunction blocs IP address as ID & LOC Separation of Host ID from IP address Host ID and Local LOC (HILL) IP address based communication HID-based communications Global IP-based routingLocal LOC-based routing Combined data delivery and control Separation of control plane from data delivery Dynamic Distributed Mapping System (DDMS) Static Centralized Mapping b/w ID&LOC Dynamic Distributed ID/LOC Mapping System Data-driven packet delivery for mobile hosts Route optimization using location query Query-First Data Delivery (QFDD)

16. Three Functional Blocks Geneva, Switzerland, 11 June 201216

17. HILL: Host ID & Local Locator (HID-based global comm. & LOC-based local routing) Geneva, Switzerland, 11 June 201217 Advantages Free from address depletion problem Not require globally unique address allocation (e.g. IPv4/6) Make private-to-private network communication possible very easily More efficient to support mobility and multi-homing Help to resolve the BGP routing table explosion problem Secure HID provides security and privacy

18. DDMS: Dynamic Distributed Mapping System Advantages More efficient management than Agent-based Centralized LM of legacy Internet for mobile dominant environment ITO, single point of failure, unwanted traffic introduction, etc. Geneva, Switzerland, 11 June 2012 18

19. QFDD: Query First Data Delivery Geneva, Switzerland, 11 June 201219 Advantages More efficient delivery than the Send-First of legacy Internet for mobile dominant environment ITO, optimized routing path, reduction of unwanted traffic introduction, transmission delay, etc.
