There is nothing to confirm with any certainty that even
though Comcast may be remarking QoS values upon ingress to
their network, that those (new) markings actually have any
(forwarding) meaning in their network.
As someone stated before, relying on QoS for regular IP
Transit traffic is tenuous at best.
