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 determines with what intervals
trickled
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.
This parameter is customizable on a per-application basis via
trickled.conf5.
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.conf5.
-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 consumption 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.
