I am very much interested in this issue. Also I had a couple
of times for relevant discussion within MobOpts in terms
of MIP option for connectivity-change indication. Now, I
am trying to revise it based on recent feedbacks from IETF.
Anyway, one concern occurs in my mind regarding TCP
option for connectivity-change indication. In case host
changes its point of attachment (typically called handover),
TCP operations will happen after all IP/MIP operation
are completed. It seems a bit serious than MIP option
from the service disruption. By enabling simple interface
between MIP and Trnasport laer (TCP), indication included
in MIP option can be used for TCP module. In case we do
not consider handover (for example: wireless interference,
etc), TCP option seems a bit useful than MIP approach.
I am not sure MIP option can be applied for the case above.
