Hi Fred
I think that one of the goals of the PCN WG will be to investigate
the implications of using ECN and/or DSCP for PCN encoding purposes.
Best Regards,
Georgios

actually, I do, at least in some ways that they might be
used. The AF service (RFC 2597) is specifically designed to
do as you say; EF isn't. setting the DSCP on an EF packet in
a way that nullifies its EF behavior to communicate the onset
of congestion mostly nullifies the EF service (which doesn't
actually do much of anything when there is no congestion to
perturb packet timing). So I would want any use of the DSCP
to be coordinated with the other services that the datagram hopes for.
