+
+.SH DESCRIPTION
+Proportional Integral controller-Enhanced (PIE) is a control theoretic active
+queue management scheme. It is based on the proportional integral controller but
+aims to control delay. The main design goals are
+ o Low latency control
+ o High link utilization
+ o Simple implementation
+ o Guaranteed stability and fast responsiveness
+
+.SH ALGORITHM
+PIE is designed to control delay effectively. First, an average dequeue rate is
+estimated based on the standing queue. The rate is used to calculate the current
+delay. Then, on a periodic basis, the delay is used to calculate the dropping
+probabilty. Finally, on arrival, a packet is dropped (or marked) based on this
+probability.
+
+PIE makes adjustments to the probability based on the trend of the delay i.e.
+whether it is going up or down.The delay converges quickly to the target value
+specified.
+
+alpha and beta are statically chosen parameters chosen to control the drop probability
+growth and are determined through control theoretic approaches. alpha determines how
+the deviation between the current and target latency changes probability. beta exerts
+additional adjustments depending on the latency trend.
+
+The drop probabilty is used to mark packets in ecn mode. However, as in RED,
+beyond 10% packets are dropped based on this probability.  The bytemode is used
+to drop packets proportional to the packet size.
+
+Additional details can be found in the paper cited below.
+
+.SH PARAMETERS
+.SS limit
+limit on the queue size in packets. Incoming packets are dropped when this limit
+is reached. Default is 1000 packets.
+
+.SS target
+is the expected queue delay. The default target delay is 20ms.
+
+.SS tupdate
+is the frequency at which the system drop probability is calculated. The default is 30ms.
+
+.SS alpha
+.SS beta
+alpha and beta are parameters chosen to control the drop probability. These
+should be in the range between 0 and 32.
+
+.SS ecn | noecn
+is used to mark packets instead of dropping
+.B ecn
+to turn on ecn mode,
+.B noecn
+to turn off ecn mode. By default,
+.B ecn
+is turned off.
+
+.SS bytemode | nobytemode
+is used to scale drop probability proportional to packet size
+.B bytemode
+to turn on bytemode,
+.B nobytemode
+to turn off bytemode. By default,
+.B bytemode
+is turned off.
