Dear all,

I would like to announce that we (myself and Grenville Armitage) released Dummynet AQM v0.2, which is an independent implementation of CoDel, FQ-CoDel PIE and FQ-PIE* for FreeBSD's ipfw/dummynet framework, based on the IETF  CoDel [1], FQ-CoDel [2] and PIE [3] Internet-Drafts.

* "FlowQueue-PIE" (FQ-PIE) implementation combines FQ-CoDel's FlowQueuing with PIE's individual queue management.

In addition to PIE and FQ-PIE, this version includes bugs fixing and improvements to CoDel and FQ-CoDel code.

We prepared patches for FreeBSD11-CURRENT-r297692  and FreeBSD 10.x-RELEASE (10.0, 10.1, 10.2, 10.3), and a technical report  of our implementation.

Patches and documentation can be found in:
