Introduction: The Ubiquitous Internet

Internet

How can we achieve the ubiquitous Internet:

Everywhere: home appliances, products sold at shops, in street furnitures, in-vehicles, on people and animals, ... Always connected to the Internet

Wireless LAN 802.11

Private Internet Access

DSRC / M5

In-vehicle Internet Access Changing access network

Wired or Wireless LAN (WaveLAN, HiperLAN,..)

Internet Access at Office

Picocellular MAN

Public Internet Access Changing access network Changing access network

Key issues: mobility in & between access networks and in-vehicle access

IP-layer Mobility: Host Mobility and Network Mobility

Address Requirements for IPv6 nodes:

Must be topologically correct Each interface must have an address formed after the prefix advertised on the link where it is attached

IP-layer Mobility

Change of point of attachment = change of IP subnet Change of IP subnet = change of the routing directive

MR_HoA: MR's egress interface on home link

Movement to Foreign Link

MR retains HoA

MR obtains CoA on its visited link

CoA is bound to NEMO-prefix, not HoA

Benefit of network mobility support over host mobility support

Network Mobility Support (NEMO Basic Support)

The vehicle changes its point of attachment to the Internet

Host Mobility: each node maintains Internet access

Each host must perform Mobile IPv6

Network Mobility: only the mobile router (MR) maintains Internet access

Standards IPv6 nodes can be located behind the MR: no mobility support

Host Mobility Support (Mobile IPv6)

Mission Oriented Project: Nautilus http://www.nautilus6.org Created Feb.2003

Co-located at K2 (Shin-Kawasaki, Japan) with KAME & USAGI Japan: mostly Keio University, + people from Tokyo U, IIJ Intl: ULP Strasbourg, ENST-B, FT R&D, INT Paris, Seoul National Univ. Cooperation with USAGI, KAME, SOI, ICAR, ECARE

Objective: Demonstrate IP-layer mobility and proceed to deployment

Show how IPv6 mobility features could be Implemented, integrated, promoted & deployed In a operational, secure and efficient environment

Missions:

Establish the necessary communication system and protocol suite

Implement protocols if existing implementations cannot be used Push for and contribute to IETF standardization of newly designed protocols if existing standard are not appropriate Integration, Validation, Demonstration

Pursue research in enhanced mobility features Promotion, Education

Show the business reality of IP mobility to convince business players Perform field trials with business players Explore the nation-wide business operation

Nautilus: Activities Mobile IPv6 (Mobile IPv6) Network Mobility (NEMO)

Implementation / Test / Validation NEMO Basic Support Research into Route Optimization, Nested NEMO, etc

Multihoming (multiple interfaces, multiple routers, etc)

Problem Statement / Test / Reseach

Seamless Mobility (fast vertical & horizontal handoffs, etc)

Implementation Research: French partners (ULP)

Security and Access Control (for mobility)

Integrate existing implementation

Services and Applications (for mobility)

For demonstration purposes

Operational and Evaluation

Performance Analysis of the Communication System

Multicast

Nautilus Strategy: Development Steps Each protocol goes through a number of steps:

Specification Implementation Validation Demonstration Integration with the overall system architecture Operational validation and evaluation Actual deployment

Protocols are not developed at the same pace

MIP6 is almost operational; NEMO implementation is under validation; we still don't have a clear roadmap for seamless, etc

Testbeds must be designed accordingly

Phase-1: Demonstration Testbed Goal:

Demonstrate the combination of host-mobility, network mobility and benefits of multhoming

How:

Design generic testbed that can be used for distinct usages Usages: E-Walker / E-Back / E-Bike /E-Wheechair i.e. as you like

What

Nested mobile network Live video streaming and monitoring Permanent access using distinct access mediums

Interface switching (horizontal & vertical handoffs) Flow(s) is adapted to bandwidth.

Conclusion Objective is to demonstrate IP-layer mobility Large spectrum of activities We have expertise in

Areas: host mobility, network mobility, seamless mobility, multihoming Methods: Implementing, demonstrating things

We lack skills in:

Areas: security, access control, QoS Methods: performance evaluation (analysis, simulation)

We need:

Demonstrative applications Consider new usages and their specific needs

Our testbed can be used as a framework to conduct further research and develop new paradigms
