Hi – Comcast is working on the implementation of ultra-low latency
networking, leveraging the IETF’s upcoming L4S standard. 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

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

Thank you!
Jason Livingood
