  1. Joint ITU-T SG 13 and ISO/JTC1/SC 6 Workshop on “Future Networks Standardization”(Geneva, Switzerland, 11 June 2012) Future Network: Mobility Tae-Wan You ETRI, twyou@etri.re.kr

  2. Outline • Overview of ISO/IEC WD 29181-4 • Future Network: Problem Statements and Requirement – Part 4: Mobility • Introduction to R&D Project in Korea • MOFI: Mobile-Oriented Future Internet • Architecture of Future Internet for Mobile Environment • Project sponsored by Korean government

  3. ISO/IEC 29181-4: Status • ISO/IEC JTC1/SC6/WG7 • Editors: • Seok-Joo Koh (Korea) • Maryam Roshanaei (UK) • Status • 3rd WD (as of May 2012) • Plan • PDTR Ballot (Sep. 2012)

  4. ISO/IEC 29181-4: Status

  5. Motivations • Paradigm Shift: from Fixed to Mobile • “Mobility” is a key factor in the design of FN

  6. Mobile environment in FN

  7. Mobile environment in FN

  8. Related works on mobility in FN • SDO • IETF: Mobile IP, Proxy Mobile IP, etc • ITU-T: Q.22/13 (Mobility Management) • ISO/IEC JTC1/SC6: WG7 (Future Network) • R&D Projects • eMobility (FP7) • FIND, GENI • AKARI (Japan) • MOFI (Korea)

  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

  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

  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

  12. Mobile‐Oriented Future Internet (MOFI) http://www.mofi.re.kr 12

  13. MOFI (www.mofi.re.kr)

  14. Project Overview

  15. Problems vs. Design Principles

  16. Three Functional Blocks

  17. HILL: Host ID & Local Locator(HID-based global comm. & LOC-based local routing) • 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.

  19. QFDD: Query First Data Delivery • 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.

  20. Overall Architecture

  21. Data Delivery Model

  22. Overall Mapping System

  23. Implementation Status • Linux-based Implementation • Kernel based AR and Local Mapping system • IPv6 based HID, convention IPv6 application • Click-based Implementation • AR and Host developed by Click Modular Router • MOFI Proxy Agent (MPA) developed • NS-3 Simulator • MOFI’s full spec. developed by NS-3 • Data and control plane, handover scenario

  24. Conclusions and Recommendations • Conclusions • “Mobility” is one of the key issues in Future Network • Current focus on “Problem Statement and Requirement” in the JTC1/SC6 • Several projects are progressed in the world • Recommendations • Collaboration is needed between JTC1/SC6 and ITU-T SG13 for global standardization • Possible items • Requirement • Architectural Design • Identification, etc
