Agreed. Standard practice at every place Ive worked has been to remark DSCP
to 0 on ingress for all Internet traffic.

sorry let me be clear,
resetting dscp bits to 0 (or other internal classify for best effort) is
normal for large ISP's with internal qos policies. proper behaviour is to
leave last two bits alone for ECN, but I doubt ecn bits are passed across
the internet freely.

My understanding that is the de facto standard for most large SP's .
Especially if they run their own qos policies internally.

All,
I am wandering if other networks modify the DSCP of internet
customers when they receive the traffic from the customer (such as resetting
it to BE for all traffic). What is seen as being best practice for this
operation.
