trickle — a lightweight userspace bandwidth shaper
|trickle|| [-h] [-v] [-V] [-s] [-d |
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:
Increases the verbosity level (can be specified multiple times).
Runs trickle in standalone mode, independent of trickled(8).
Limit the download bandwidth consumption to
Limit the upload bandwidth consumption to
Set peak detection window size to
lengthKB. 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.
Set smoothing time to
secondss. The smoothing time determines with what intervals trickle will try to let the application 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.
Set smoothing length to
lengthKB. 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
lengthKB of data. The default value is 10 KB.
Use trickled(8) socket
pathto communicate with trickled(8). By default,
trickle -u 10 -d 20 ncftp
Launch ncftp(1) limiting its upload capacity to 10 KB/s, and download capacity at 20 KB/s.
