https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241563 Bug ID: 241563 Summary: [PATCH] Adaptive RED for pf altq Product: Base System Version: 12.0-RELEASE Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: architpandeynitk@gmail.com Created attachment 208668 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=208668&action=edit Diff file with changes FreeBSD's PF firewall allows traffic shaping using Random Early Detection (RED). RED helps keep the average size of the queues low and allow occasional bursts of packets through the queue. Adaptive RED (ARED) was proposed by Floyd et. al. [1] as an enhancement over RED. ARED solves most of the issues faced by RED with minimal changes and leaves its basic idea intact. The ARED algorithm regularly adapts the value of the maximum dropping probability and ensures that the queue length stays within the targeted range. This patch implements ARED in PF ALTQ. It can be enabled by compiling the kernel with option ALTQ_ADAPTIVE_RED. The patch has been tested on FreeBSD-12.0-RELEASE. The results obtained from applying the patch have been included in our paper "Adaptive RED for FreeBSD: Design, Implementation and Challenges", recently presented at TENCON 2019.
