I think that it is important that QoS is active for the whole
connection.  So if the path is intially on an unoptimised route, QoS
should still be established.

Sorry what do you mean by optimisations?

After more careful look into the issue raised by Murray Philip, now I
realize that there are a number of possible routes MN's packets may take
after handover:

1. Non-optimized path which includes a segment from CN to HA and another
from HA to MN.

2. Optimized path from CN to MN.

3. Temporary tunnel between old and new access routers created by some
mobility protocols such as fast handover (note that even though the
routers
may be physically adjacent, this tunnel could be a long one, possibly
even
crossing the core).

Is it absolutely required to provide QoS support on all these segment?
Or
shall we just say that it is required to provide QoS support on
optimized
path and leave others as optimizations.?
