Le support des réseaux mobiles dans IPv6

Traditional work turning around mobility support has usually focused on host mobility, i.e. single terminals which change their point of attachment in the Internet topology, whereas the most current type of mobility in IPv6 is probably going to be network mobility, i.e. entire IPv6 networks which border routers change their point of attachment to the Internet topology. Mobile networks are expected to be found in access networks deployed in public transportation, and networks of sensors installed in vehicles. Without specific support mechanisms, changing the point of attachment results into broken sessions. Protocols such as Mobile IPv6 designed to support host mobility are either inappropriate or inefficient to support network mobility. Extensions to Mobile IPv6 have therefore been proposed and are currently discussed in the IETF NEMO working group. The purpose of this paper is to explain the problem caused by network mobility in IPv6 and to overview the current activities of this promising topic.
