Our paper has some data - again, fig. 4. That=E2=80=99s an AS level =
analysis, for the data that we had (which wasn=E2=80=99t huge - a couple =
thousand paths). For the majority of measurements, the DSCP survived =
more than 1 AS hop; in case of IPv6, the majority survived more than 2.

Cheers,
Michael
