Frederic Lecaille b47e1e65df BUG/MINOR: quic: fix BBB max bandwidth oscillation issue. 
Remove the code in relation with BBR.ack_phase as per this commit:
ee98c12ad6

I do now kwow at this time why such a request was pushed on GH for the BBR v3 draft
pseudo-code. That said, the use of such an ack phase seemed confusing, adding much
more information about a BBR flow state than needed. Indeed, the ack phase
state is modified several times in the BBR draft pseudo-code but only used to
decide if the max bandwidth filter virtual clock had to be incremented by
BBRAdvanceMaxBwFilter().

In addition to this, when discussing about haproxy BBR implementation with
Neal Cardwell on the BBR development google group about an oscillation issue
of the max bandwidth (BBR.max_bw), I concluded that this was due to the fact
that its filter virutal clock was too often update, due to the ack phase wich
was stalled in BBR_ACK_PHASE_ACKS_PROBE_STOPPING state for too long. This is
where Neal asked me to test the aforementioned commit. This definitively
makes the max bandwidth (BBR.max_bw) oscillation issue disappear.

Another solution would have been to add a new ack phase enum afer
BBR_ACK_PHASE_ACKS_PROBE_STOPPING. BBR_ACK_PHASE_ACKS_PROBE_STOPPED
would have been a good candidate.

Remove the code in relation with BBR.ack_phase.

Must be backported to 3.1.

HAProxy logo

HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.

Installation

The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.

Getting help

The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.

The issue tracker is only for bug reports or feature requests.

Documentation

The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.

Please refer to the following files depending on what you're looking for:

  • INSTALL for instructions on how to build and install HAProxy
  • BRANCHES to understand the project's life cycle and what version to use
  • LICENSE for the project's license
