That is an abstract nonsense by you and others who do not understand layering at all, which constitutes part of the collective stupidity. QoS (not CoS but real QoS) capable routers must inspect L4. Though fragmentation is generally prohibited for QoS, it is merely because increased link overhead changes bandwidth requirement, which does not mean QoS capable routers are acting as a host. > As Fred pointed out, existing devices already emulate reassembly without > emmitting the reassembled result. As I pointed out, if it were acceptable, we could widely accept fragmentation overhead.
