Re: BCP regarding TOS transparancy for internet traffic

The "general population", who does NOT pay for that privilege, gets the BE-treatment, which is what they pay for. And that requires a rewrite of the DSCP/TOS for said traffic, otherwise how do you prevent packets from the "general population" filling up the queues you have reserved for theOne way is to null MPLS EXP for BE traffic and do QoS on that, and then set EXP bits to something different for non-BE traffic. That leaves DSCP transparent end-to-end on the IP packet.
But as I have read the discussion I do think that null:ing DSCP for all BE traffic is the way to go, and keep the clean copy of DSCP to EXP within the network for the customers paying for preferred treatment (or whatever service you want to prioritize).
