Mobile IPv6: Underpinning the Future Mobile Internet

The "anytime, anywhere" Internet depends on a lot of technology that hasn't been developed yet.It's not even so sure that we can grow the Internet past the one billion mark without significant changes in the current technical directions.In this presentation, I describe Mobile IPv6, one possible new approach to the problem.Working from the solid underpinnings of IPv6 to obtain the necessary address space and low-level features of address management, Mobile IPv6 is likely to emerge as the most economical and efficient solution to the problems of global mobility management.It has been designed to simplify Internet connectivity for wireless devices, which have traditionally been restricted to movement within domains managed by layer-2 mechanisms.As Mobile IPv6 approaches Proposed Standard, new work has focussed on devising protocols and solutions for problems of seamless handovers, transfer for context features between access routers, and new security models.The result should be substantially improved roaming capabilities, even between dissimilar media, and all at lower prices.I will describe these areas of interest, and also give some idea of the future challenges facing the continued development of the converged mobile Internet.
