Mr. Jason:
Thank u for the reply, very informative URL. Understood
on the cap, but how long it will remain not enforced is
a good guess! What I am trying to is have Comcast mark
our IP ranges with QoS, so downloads or congestion
inside the household will not degrade performance. You
can see at

ation that this is the configuration for Microsoft Xbox.
Do you know what this service is called and who at
Comcast can help me with the commercials?

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.
