   This document provides recommendations of best current practice for
   dropping or marking packets using any active queue management (AQM)
   algorithm, including random early detection (RED), BLUE, pre-
   congestion notification (PCN) and newer schemes such as CoDel
   (Controlled Delay) and PIE (Proportional Integral controller
   Enhanced).  We give three strong recommendations: (1) packet size
   should be taken into account when transports detect and respond to
   congestion indications, (2) packet size should not be taken into
   account when network equipment creates congestion signals (marking,
   dropping), and therefore (3) in the specific case of RED, the byte-
   mode packet drop variant that drops fewer small packets should not be
   used.  This memo updates RFC 2309 to deprecate deliberate
   preferential treatment of small packets in AQM algorithms.
