Hi, Alex.

Plz, see inline. I fully failed to understand your words.

In the context of ITS communication, how do you expect the movement of
vehicles? Then, how do you decide the location of home agent for
reducing the routing performance for user data packets destined to
hosts attached to the router of a vehicle?

In the context of this thread, Bob mentioned about the routing
performance, exactly saying user data packets' routing performance,
not saying handover latency mainly consisted of 1) movement detection
at IP level; 2) address configuration; and 3) location update (BU/BA)
to the home agent.

Cheers.
