Re: [Diffserv] DHCP user class

Brian,

At the very least the first half of the current introduction
is a speculative description of a service differentiation scheme
that hasn't been documented anywhere else in the IETF to my
knowledge. There are no citations to models. I hope the IESG will
request that the document authors either clarify the relationship
between Diffserv/Intserv and their service differentiation model,
or simply remove the 'classify on source address' example.

cheers,
gja
