I would support Greg's comment above. I would add that the DSCP discussed in 
the draft is called the "Traffic Class" in IPv6 (cf RFC 8200), and it would be 
nice to add an explanatory sentence somewhere observing on the fact. On the 
first usage of "DSCP", in addition to the link to RFC 2474, perhaps it should 
be expanded to "DSCP, Traffic Class [RFC8200], or Traffic Class [correct MPLS 
RFC]". Or something equivalent.

On a technical note, it seems strange to refer to a Cisco proprietary queue 
management structure (MDRR, cf 
https://www.cisco.com/c/en/us/support/docs/routers/12000-series-routers/18841-mdrr-wred-18841.html)
 and a research paper intended for EPON networks (PWFQ, 
http://adsabs.harvard.edu/abs/2005SPIE.6022..220X), but not the diffserv 
architecture, or at least without explaining that the "policing policy" etc 
derive from diffserv.
