trickle — a lightweight userspace bandwidth shaper

trickle has been developed by Marius Aamodt Eriksen ⟨marius@monkey.org⟩.

       Does not support executables utilizing kqueue(2).  Does not support statically linked executables.

Debian                                          November 10, 2002                                     TRICKLE(1)

trickle is a userspace bandwidth manager.  Currently, trickle supports the  shaping  of  any  SOCK_STREAM
       (see  socket(2))  connection established via the socket(2) interface.  Furthermore, trickle will not work
       with statically linked executables, nor with setuid(2)  executables.   trickle  is  highly  configurable;
       download and upload rates can be set separately, or in an aggregate fashion.

       The options are as follows:

       -h           Displays help.

       -v           Increases the verbosity level (can be specified multiple times).

       -V           Prints version.

       -s           Runs trickle in standalone mode, independent of trickled(8).

       -drate      Limit the download bandwidth consumption to rate KB/s.

       -urate      Limit the upload bandwidth consumption to rate KB/s.

       -wlength    Set  peak  detection window size to length KB.  This determines how aggressive trickle is at
                    eliminating bandwidth consumption peaks.  Lower values will be more aggressive, but may also
                    result in over shaping.  The default value (512 KB) is usually sufficient.

       -tseconds   Set smoothing time to seconds s.  The smoothing time determines with what intervals  trickle
                    will  try  to  let  the  application  transceive data.  Smaller values will result in a more
                    continuous (smooth) session, while larger values may  produce  bursts  in  the  sending  and
                    receiving  data.   Smaller  values  (0.1 - 1 s) are ideal for interactive applications while
                    slightly larger values (1 - 10 s) are better for applications that need bulk transfer.

       -llength    Set smoothing length to length KB.  The smoothing length is  a  fallback  of  the  smoothing
                    time.   If  trickle  cannot  meet the requested smoothing time, it will instead fall back on
                    sending length KB of data.  The default value is 10 KB.

       -npath      Use   trickled(8)   socket   path   to   communicate   with   trickled(8).    By    default,
                    /tmp/.trickled.sock is used.

       -Ppath      Use  the  specified .so instead of the standard one, this is useful if you don't run trickle
                    from a standard installation.

trickle-u10-d20ncftp

       Launch ncftp(1) limiting its upload capacity to 10 KB/s, and download capacity at 20 KB/s.
