La mobilité des réseaux IPv6, usage et démonstration IPv6 Network Mobility, usage and demonstration

Cette présentation a pour but d'informer le lecteur des récentes recherches et usages de la mobilité des équipements et des réseaux dans le domaine de l'Internet. Nous expliquerons d'abord ce qu'est le protocole IPv6 et pourquoi un tel protocol est indispensable pour atteindre les buts que nous nous sommes fixés. Nous aborderons ensuite différents aspects de la mobilité: celle des stations puis celle d'un réseau tout entier, tout en essayant de démontrer les avantages et l'utilité de tels protocoles. Nous verrons ensuite que ces travaux nécessitent une étroite collaboration avec des équipes et laboratoires d'autres pays, afin de pouvoir lier nos efforts sur les spécifications, implémentations et démonstrations de ces nouvelles technologies. This presentation aims at informing the reader of the recent research and usages about host and network mobility in the Internet. We will first explain what is the IPv6 protocol, and why we need it to achieve our goals. We will then talk about the different aspects of mobility: host mobility and network mobility, trying to show advantages and usages of such protocols. We will also explain that research in this topic needs tight collaborations between several laboratories located in different countries, in order to work together on specifications, implementations and demonstrations of these new technologies. Intoduction Nowadays, more and more devices are connected to the Internet, and people would like to stay connected anywhere and anytime: we speak about ubiquitous internet computing. In order to satisfy these needs, we need to design and develop new solutions. The ones we use today in the network world were created at a time when we were not aware of those possibilities. The Nautilus6 working group [NAUTILUS6], based at Keio university, Japan, was established within the WIDE organization in spring 2003 to demonstrate how the IPv6 protocol and its mobility features could be deployed. We will thus discuss about the solutions and collaborations with foreign laboratories that can lead us to achieve these goals
