This stand= ard 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 While any network operator is welcome to take this, we are particularly interested in any networks that are directly interconnected with us today.
