+From d4b36210c2e6ecef0ce52fb6c18c51144f5c2d88 Mon Sep 17 00:00:00 2001
+From: Vijay Subramanian <vijaynsu@cisco.com>
+Date: Sat, 4 Jan 2014 17:33:55 -0800
+Subject: net: pkt_sched: PIE AQM scheme
+
+Proportional Integral controller Enhanced (PIE) is a scheduler to address the
+bufferbloat problem.
+
+>From the IETF draft below:
+" Bufferbloat is a phenomenon where excess buffers in the network cause high
+latency and jitter. As more and more interactive applications (e.g. voice over
+IP, real time video streaming and financial transactions) run in the Internet,
+high latency and jitter degrade application performance. There is a pressing
+need to design intelligent queue management schemes that can control latency and
+jitter; and hence provide desirable quality of service to users.
+
+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. "
+
+Many thanks to Dave Taht for extensive feedback, reviews, testing and
+suggestions. Thanks also to Stephen Hemminger and Eric Dumazet for reviews and
+suggestions. Naeem Khademi and Dave Taht independently contributed to ECN
+support.
+
+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
