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 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.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 consumption
		  peaks.  Lower values will be more aggressive, but may also result in over shaping.  The default value (512 KB) is usually suffi-
		  cient.

EXAMPLES

     trickled -u 10 -d 20

     Limit aggregate trickle(1) upload bandwidth consumption to 10 KB/s and download consumption to 20 KB/s.

NAME

       tswtclmt - Time Sliding Window Three Conformance Level Meter

DESCRIPTION

       The Time Sliding Window Three Conformance level meter (tswtcl) meters a traffic stream and determines the conformance level of its packets.

       Packets are deemed to belong to one of the three levels, Red, Yellow or Green, depending on the committed and peak rate.

       The meter provides an estimate of the running average bandwidth. It takes into account burstiness and smoothes out its estimate to  approx-
       imate the longer-term measured sending rate of the traffic  stream.

       The estimated bandwidth approximates the running average bandwidth of the traffic stream over a specific  window  (time	interval).  tswtcl
       estimates  the  average	bandwidth  using a time-based estimator. When a packet arrives for a class, tswtcl re-computes the average rate by
       using the rate in the last window (time interval) and the size of the arriving packet. The window is then slid to start at the current time
       (the packet arrival time). If the computed rate is less than the committed configuration parameter, the packet is deemed Green; else if the
       rate is less than the peak rate, it is Yellow; else Red. To avoid dropping multiple packets within a TCP window,  tswtcl  probabilistically
       assigns one of the three conformance level to the packet.

STATISTICS

       The tswtcl module exports global and per-class statistics through kstat:

       Global statistics:

       module: tswtclmt 			instance: <action id>
	 name: tswtclmt statistics		class <action name>
	       green_bits		       <number of bit in green>
	       green_packets		       <number of packets in green>
	       red_bits 		       <number of bits in red>
	       red_packets		       <number of packets in red>
	       yellow_bits		       <number of bits in yellow>
	       yellow_packets		       <number of packets in yellow>
