Introduction: The Ubiquitous 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 In-vehicle Public Changing Internet Internet access Access Changing Access network Changing access Picocellular MAN access DSRC / M5 network network Internet Access at Private Office Internet Wired or Wireless LAN Access (WaveLAN, HiperLAN,..) Wireless LAN 802.11 Internet Key issues: mobility in & between access networks and in-vehicle access 2 Thierry Ernst - Nautilus6.org - September 2004
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 BR BR Change of point of attachment = change of IP subnet Change of IP subnet = change of the routing Prefix1::id_MN Prefix1::id_MN directive AR Prefix1 Prefix1 Prefix1::id_MR Prefix1::id_MR HA MN MN Prefix2::id_MR Prefix2::id_MR Prefix2::id_MN Prefix2::id_MN AR AR Prefix2 Prefix2 Prefix1.1::id_MR Prefix1.1::id_MR Prefix1.1::id_MR Prefix1.1::id_MR MN MN Prefix1.1::id_MR Prefix1.1::id_MR 3 Thierry Ernst - Nautilus6.org - September 2004

Benefit of network mobility support over host mobility 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 Network Mobility Support (Mobile IPv6) (NEMO Basic Support) 5 Thierry Ernst - Nautilus6.org - September 2004
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 6 Thierry Ernst - Nautilus6.org - September 2004
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 7 Thierry Ernst - Nautilus6.org - September 2004
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 8 Thierry Ernst - Nautilus6.org - September 2004
