I agree with Gory.

I believe you missed the most important point, i.e. explaining in the 
text that the RFC2309 is obsolete.
For example:

     "Back in 1998, RFC 2309[RFC2309], now obsoleted by RFC7567,
     strongly recommended the adoption of AQM schemes in the network to
     improve the performance of the Internet."
