  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.
