I took note of nw_tos=, ip_dscp=, nw_ecn=, and ip_ecn= for DSCP and ECN
matching and mod_nw_tos:, mod_nw_ecn:, mod_nw_ecn: for setting DSCP and
ECN values.
So the DiffServ functionality would have to be implemented on OVS ...
Correct?
And could be implemented as a layer on OVS ... Correct?
Does anything currently do this?

For example:

RFC 2475: An Architecture for Differentiated Services
RFC 2697: A Single Rate Three Color Marker
RFC 2698: A Two Rate Three Color Marker
*** RFC 2474 and RFC 2475 are more architectural issues than specific
services / functionality.
But does OVS provide RFC 2697 and RFC 2698 ... for example?
OK, I don't know how OVS would "provide" these RFCs.
OVS permits matching on and modifying the DSCP field. If you have a
question about how that can be used to implement some specific
functionality, then we can talk about that.
