Proportional Integral controller Enhanced (PIE) is a scheduler to address the
bufferbloat problem.

We present here a lightweight design, PIE(Proportional Integral controller
Enhanced) that can effectively control the average queueing latency to a target
value. Simulation results, theoretical analysis and Linux testbed results have
shown that PIE can ensure low latency and achieve high link utilization under
various congestion situations. The design does not require per-packet
timestamp, so it incurs very small overhead and is simple enough to implement
in both hardware and software.  "

For more information, please see technical paper about PIE in the IEEE
Conference on High Performance Switching and Routing 2013. A copy of the paper
can be found at ftp://ftpeng.cisco.com/pie/.

Please also refer to the IETF draft submission at
http://tools.ietf.org/html/draft-pan-tsvwg-pie-00

All relevant code, documents and test scripts and results can be found at

    After a decade of trying to deprecate the old policer syntax,
    I believe it is time to kill it. The kernel build option for old
    policer is gone for at least 5 years now (although backward
    compatibility is still there). Being backward compatible meant
    hijacking the keyword "action" and was obstructing policies like:

    tc filter add dev eth0 parent ffff: protocol ip pref 10 \
    u32 match ip protocol 1 0xff flowid 1:10 \
    action skbedit mark 1 \
    action police rate 10kbit burst 10k pipe \
    action skbedit mark 2 \
    action police rate 20kbit burst 20k pipe \
    action action mirred egress mirror dev dummy0
