[Cerowrt-devel] edgerouter LTE beta w/fq_codel upcoming

[Dave Taht]

As I pointed out here,  there is more work to be done  on that  front

http://community.ubnt.com/t5/EdgeMAX/S-FQ-CoDel-Support-Possible/m-p/799394#M28651

Mostly  my hope  is to get a SQM-like shaper/aqm/scheduler rewritten
in  the vyatta command  language that works at  rates  up  to 200Mbit.

All the published examples  have problems:

http://www.five-ten-sg.com/mapper/bufferbloat  for  example,  uses SFQ
and a very small queue length that is probably ineffective.

There  have been various other  examples forwarded to  me that all
need  some love,
including  one  very elaborate one that uses ifb semi-correctly, and
then goes nutso  with
ack prioritization.  (can't find any of these now)

...

And  it did look that adding BQL support was easily possible for  the
underlying driver,  but I didn't  sink  any time  into  that  - the
key "driver" (it's really an  interface   to a binary blob) is  in:

drivers/net/ethernet/octeon

and  it's  unclear  how much buffering is built into  the blob.
