In HMIPv6 (RFC5213), a mobile node has three IPv6 addresses: HoA,
RCoA and LCoA. Outside the domain of a MAP, RCoA is used for
routing, while HoA is used for authentication. Hence HA and CN
should maintain the binding of RCoA and HoA. Inside the domain of a
MAP, RCoA is used for authentication, while LCoA is used for routing.
Hence MAP should maintain the binding of RCoA and LCoA. Since RCoA
is used for authentication, it should be unique to a mobile node.
Therefore, how many mobile nodes there are inside domain of a MAP,
how many different RCoAs the MAP has to allocate to the mobile nodes.
In this Internet Draft, an improved or alternative solution to HMIPv6
is presented, where RCoA is no longer used for authentication inside
the domains of a MAP. RCoA is used only for routing outside the
domain of a MAP, as LCoA does inside the domain of a MAP. Inside the
domain of a MAP, HoA is used for authentication, as it does outside
the domain of a MAP. Since RCoA is no longer used for
authentication, only one RCoA will be enough for all mobile nodes
inside the domain of a MAP.
Remark: This Internet Draft is based on HMIPv6 (RFC5380). Only those
parts in HMIPv6 related to RCoA have been rewritten, while the other
parts in HMIPv6 remain almost unchanged.
