  2. target restored to 5ms

    Dave Taht committed
    fiddling with target accomplishes very little on the current
    codel implementation, and in fact, hurts.

    Dave Taht committed
    600 proved to induce drop tail behavior at high rates.
    Arbitrarily doubling.

  2. debloat: smaller quantums seem to be better

    Dave Taht committed
    despite intuition saying we wanted packet aggregation to work better,
    smaller quantums seem to work better.

  1. quagga: add config notes for redistribute kernel and rxcost

    Dave Taht committed
    I use the rxcost parameter to give a mild bias to the 5.x
    ghz radios. In the test deployment I found it necessary to bump up
    rxcost in proportion to the radio's quality and intent.
    so I ended up with rxcost of 1024 and 1023 for wndr3800s
    rxcost of 768 for picostation 2HPs (used by users)
    rxcost 256 for the directional nanostation M5 backbone
    This gave the m5 radios preference and only in case of failure
    do things fall back to the 2HPs and wndr3800s. Otherwise
    the m5s would prefer a direct connection to a lousy radio
    vs a 2 hop or more route that used good radios and ethernet.
    I'm not saying this is correct, but it worked.
    redistribute kernel works correctly for dhcpv4 inserted default
    routes. It does not appear to work correctly for RA inserted
    ipv6 routes, nor has it been tested for other forms of ipv6 routes
    as yet. WIP.

  4. Arbitrarily enable ECN on babel packets

    Dave Täht committed
    While arguably the wrong thing (babel should do something sane
    upon receipt of a ECT(3)) I am trying to analyze the behavior
    of the multicast queue which is buried deep in the stack,
    far below where it can be seen easily.
    It is my intent to monitor codel behavior by (in part) observing
    ECT(0) being asserted on babel packets via an ip6tables rule.
    In fact I intended to track all sorts of ECN behavior via iptables
    rules in the upcoming test series.
  5. Added babelm branch which contains a new smoothed metric algo

    Dave Taht committed
    I note that this experimental package also contains a patch
    to mark babel packets as ECN capable, when in reality they
    are not, at present.
    In the words of Juliusz:
    "that's a horrible kludge.  You're applying AQM to locally-originated data in
    order to compensate for the lack of backpressure, and then falsely
    asserting ECN in order to bypass the AQM policy."
    As for the first statement, queues are necessary at multiple layers
    in the stack, so I can think of no effective means of supplying
    backpressure at insertion time that will work. I can think of means of
    supplying congestion related drop indications to babel, but that is as
    yet, unimplemented.
    As to the second objection, yes this is bypassing AQM policy, however,
    at some point, using ECN marking in babel could be used for something.
    The udp markings can be easily obtained with pktinfo in userspace,
    and I do need to produce a patch for that.
    In the interim, the problem I am trying to solve is that when a rate
    change happens in wifi, it is abrupt and can take a long time (with
    the fq_codel aqm rapidly ramping up packet drop) to drop the backlog back to
    a normal level for the new rate. IMHO it is better to have a radio
    continue to function rather that potentially stop entirely because it
    dropped a bunch of babel packets while seeking a new equilibrium.

    One way to hint to old babeld to prefer one radio over an another
