Hah, just a few days ago I spoke with an "engineer" at VZ that tried to
claim that each of the treatments were different, but that they only charged
extra for EF.  I asked why I shouldn't just put all my traffic in the
highest "free" treatment and beat out all the other customers for the best
treatment for mine.  He told me that "most of his customers weren't trying
to get their traffic through at the expense of other customers".

Anyway, despite what their "engineers" say, only EF is actually treated on
the VZ network better than BE, the rest are just to prioritize traffic at
your own egress port.

Brandon,

VZ does or can apply a PE-egress profile that handles traffic differently
based on DSCP marking.  Your account team should be able to provide this to
you.

As far as unique treatment within their P network, it sure looks to me that
the higher AF classes do get better treatment.

My problem is that non-EF is handled terribly, and it's causing a big
problem with interactive traffic.  Voice is fine.

thanks.
