Comcast Network Peer Survey on DSCP/ECN for L4S

Mon Jun 13 15:54:04 UTC 2022

This seems to be missing some of the reasons/why things are remarked, perhaps it would be wise to bring some of the people interested in this to the various vendor-specific lists or such?

For example, for some hardware types, enabling any sort of rate shaping at all will rewrite the DSCP values, even for packets that do not traverse the shaped interfaces.

This standard will require passing ECN and DSCP markings across network boundaries. As a result, we are interested in your perspective on this and in how you handle markings today. We have a short survey that should only take a few minutes to complete. Take the survey at https://forms.office.com/r/vGb0LUXfS1
