TRICKLED(8) System Manager's Manual TRICKLED(8) NAME trickled -- userspace bandwidth manager daemon SYNOPSIS trickled [-h] [-v] [-V] [-f] [-s] [-d rate] [-u rate] [-t seconds] [-l length] [-p priority] [-c file] [-n path] [-N seconds] [-w size] DESCRIPTION trickled is a userspace bandwidth manager daemon. trickled manages several trickle(1) sessions at a time, shaping across multiple sessions. The options are as follows: -v Increases the verbosity level (can be specified multiple times). -V Prints version. -f Runs trickled in the foreground. -s Uses syslog for all output (instead of stderr). -d rate Limit the download bandwidth consumption to rate KB/s. -u rate Limit the upload bandwidth consumption to rate KB/s. -t seconds Set smoothing time to seconds s. The smoothing time deter- mines with what intervals trickled will try to let the appli- cation transcieve 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. This parameter is customizable on a per-appli- cation basis via trickled.conf(5). The default value is 5 s. -l length Set smoothing length to length KB. The smoothing length is a fallback of the smoothing time. If trickled cannot meet the requested smoothing time, it will instead fall back on sending length KB of data. The default value is 10 KB. -p priority Set default priority to priority. -c file Use the configuration file file. This file must be of the format documented in trickled.conf(5). -n path Set socket name to path. By default, trickled uses /tmp/.trickled.sock. -N seconds Notifies user of total bandwidth consumption every seconds s. -w size Set peak detection window size to size KB. This determines how aggressive trickled is at eliminating bandwidth consump- tion peaks. Lower values will be more aggressive, but may also result in over shaping. The default value (512 KB) is usually sufficient. EXAMPLES trickled -u 10 -d 20 Limit aggregate trickle(1) upload bandwidth consumption to 10 KB/s and download consumption to 20 KB/s.
