-#	    not checked, first match is taken. Midnight wrap (eg. 20:00-6:00)
-#	    is allowed and taken care of.
-# v0.3a4- fixed small bug in IF operator. Thanks to

-# v0.3a - added TIME parameter. Example: TIME=00:00-19:00;64Kbit/6Kbit
-#	  So, between 00:00 and 19:00 the RATE will be 64Kbit.
-#	  Just start "cbq.init timecheck" periodically from cron
-#	  (every 10 minutes for example). DON'T FORGET though, to run
-#	  "cbq.init start" for CBQ to initialize.
-# v0.2  - Some cosmetic changes. Now it is more compatible with old bash
-#	  version. Thanks to Stanislav V. Voronyi <stas at cnti.uanet.kharkov.ua>.

-#
-# README
-# ------
-#
-# First of all - this is just a SIMPLE EXAMPLE of CBQ power.
-# Don't ask me "why" and "how" :)
-#
-# This script is meant to simplify setup and management of relatively simple
-# CBQ-based traffic control on Linux. Access to advanced networking features
-# of Linux kernel is provided by "ip" and "tc" utilities from A. Kuznetsov's
-# iproute2 package, available at ftp://ftp.inr.ac.ru/ip-routing. Because the
-# utilities serve primarily to translate user wishes to RTNETLINK commands,
-# their interface is rather spartan, intolerant and requires quite a lot of
-# typing. And typing is what this script attempts to reduce :)
-#
-# The advanced networking stuff in Linux is pretty flexible and this script
-# aims to bring some of its features to the not-so-hard-core Linux users. Of
-# course, there is a tradeoff between simplicity and flexibility and you may
-# realize that the flexibility suffered too much for your needs -- time to
-# face "ip" and "tc" interface.
-#
-# To speed up the "start" command, simple caching was introduced in version
-# 0.6.4. The caching works so that the sequence of "tc" commands for given
-# configuration is stored in a file (/var/cache/cbq.init by default) which
-# is used next time the "start" command is run to avoid repeated parsing of
-# configuration files. This cache is invalidated whenever any of the CBQ
-# configuration files changes. If you want to run "cbq.init start" without
-# caching, run it as "cbq.init start nocache". If you want to force cache
-# invalidation, run it as "cbq.init start invalidate". Caching is disabled
-# if you have logging enabled (ie. CBQ_DEBUG is not empty).
-#
-# If you only want cqb.init to translate your configuration to "tc" commands,
-# use "compile" command which will output "tc" commands required to build
-# your configuration. Bear in mind that "compile" does not check if the "tc"
-# commands were successful - this is done (in certain places) only when the
-# "start nocache" command is used, which is also useful when creating the
-# configuration to check whether it is completely valid.
-#
-# All CBQ parameters are valid for Ethernet interfaces only, The script was
-# tested on various Linux kernel versions from series 2.1 to 2.4 and several
-# distributions with KSI Linux (Nostromo version) as the premier one.
-#
-#
-# HOW DOES IT WORK?
-# -----------------
-#
-# Every traffic class must be described by a file in the $CBQ_PATH directory
-# (/etc/sysconfig/cbq by default) - one file per class.
-#
-# The config file names must obey mandatory format: cbq-<clsid>.<name> where
-# <clsid> is two-byte hexadecimal number in range <0002-FFFF> (which in fact
-# is a CBQ class ID) and <name> is the name of the class -- anything to help
-# you distinguish the configuration files. For small amount of classes it is
-# often possible (and convenient) to let <clsid> resemble bandwidth of the
-# class.
-#
-# Example of valid config name:
-#	cbq-1280.My_first_shaper
-#
-#
-# The configuration file may contain the following parameters:
-#
-### Device parameters
-#
-# DEVICE=<ifname>,<bandwidth>[,<weight>]	mandatory
-# DEVICE=eth0,10Mbit,1Mbit
-#
-#	<ifname> is the name of the interface you want to control
-#		traffic on, e.g. eth0
-#	<bandwidth> is the physical bandwidth of the device, e.g. for
-#		ethernet 10Mbit or 100Mbit, for arcnet 2Mbit
-#	<weight> is tuning parameter that should be proportional to
-#		<bandwidth>. As a rule of thumb: <weight> = <bandwidth> / 10
-#
-# When you have more classes on one interface, it is enough to specify
-# <bandwidth> [and <weight>] only once, therefore in other files you only
-# need to set DEVICE=<ifname>.
-#
-### Class parameters
-#
-# RATE=<speed>					mandatory
-# RATE=5Mbit
-#
-#	Bandwidth allocated to the class. Traffic going through the class is
-#	shaped to conform to specified rate. You can use Kbit, Mbit or bps,
-#	Kbps and Mbps as suffices. If you don't specify any unit, bits/sec
-#	are used. Also note that "bps" means "bytes per second", not bits.
-#
-# WEIGHT=<speed> 				mandatory
-# WEIGHT=500Kbit
-#
-#	Tuning parameter that should be proportional to RATE. As a rule
-#	of thumb, use WEIGHT ~= RATE / 10.
-#
-# PRIO=<1-8>					optional, default 5
-# PRIO=5
-#
-#	Priority of class traffic. The higher the number, the lesser
-#	the priority. Priority of 5 is just fine.
-#
-# PARENT=<clsid>				optional, default not set
-# PARENT=1280
-#
-#	Specifies ID of the parent class to which you want this class be
-#	attached. You might want to use LEAF=none for the parent class as
-#	mentioned below. By using this parameter and carefully ordering the
-#	configuration files, it is possible to create simple hierarchical
-#	structures of CBQ classes. The ordering is important so that parent
-#	classes are constructed prior to their children.
-#
-# LEAF=none|tbf|sfq				optional, default "tbf"
-#
-#	Tells the script to attach specified leaf queueing discipline to CBQ
-#	class. By default, TBF is used. Note that attaching TBF to CBQ class
-#	shapes the traffic to conform to TBF parameters and prevents the class
-#	from borrowing bandwidth from its parent even if you have BOUNDED set
-#	to "no". To allow the class to borrow bandwith (provided it is not
-#	bounded), you must set LEAF to "none" or "sfq".
-#
-#	If you want to ensure (approximately) fair sharing of bandwidth among
-#	several hosts in the same class, you might want to specify LEAF=sfq to
-#	attach SFQ as leaf queueing discipline to that class.
-#
-# BOUNDED=yes|no				optional, default "yes"
-#
-#	If set to "yes", the class is not allowed to borrow bandwidth from
-#	its parent class in overlimit situation. If set to "no", the class
-#	will be allowed to borrow bandwidth from its parent.
-#
-# Note:	Don't forget to set LEAF to "none" or "sfq", otherwise the class will
-#	have TBF attached to itself and will not be able to borrow unused
-#	bandwith from its parent.
-#
-# ISOLATED=yes|no				optional, default "no"
-#
-#	If set to "yes", the class will not lend unused bandwidth to
-#	its children.
-#
-### TBF qdisc parameters
-#
-# BUFFER=<bytes>[/<bytes>]			optional, default "10Kb/8"
-#
-#	This parameter controls the depth of the token bucket. In other
-#	words it represents the maximal burst size the class can send.
-#	The optional part of parameter is used to determine the length
-#	of intervals in packet sizes, for which the transmission times
-#	are kept.
-#
-# LIMIT=<bytes>					optional, default "15Kb"
-#
-#	This parameter determines the maximal length of backlog. If
-#	the queue contains more data than specified by LIMIT, the
-#	newly arriving packets are dropped. The length of backlog
-#	determines queue latency in case of congestion.
-#
-# PEAK=<speed>					optional, default not set
-#
-#	Maximal peak rate for short-term burst traffic. This allows you
-#	to control the absolute peak rate the class can send at, because
-#	single TBF that allows 256Kbit/s would of course allow rate of
-#	512Kbit for half a second or 1Mbit for a quarter of second.
-#
-# MTU=<bytes>  					optional, default "1500"
-#
-#	Maximum number of bytes that can be sent at once over the
-#	physical medium. This parameter is required when you specify
-#	PEAK parameter. It defaults to MTU of ethernet - for other
-#	media types you might want to change it.
-#
-# Note: Setting TBF as leaf qdisc will effectively prevent the class from
-#	borrowing bandwidth from the ancestor class, because even if the
-#	class allows more traffic to pass through, it is then shaped to
-#	conform to TBF.
-#
-### SFQ qdisc parameters
-#
-# The SFQ queueing discipline is a cheap way for sharing class bandwidth
-# among several hosts. As it is stochastic, the fairness is approximate but
-# it will do the job in most cases. If you want real fairness, you should
-# probably use WRR (weighted round robin) or WFQ queueing disciplines. Note
-# that SFQ does not do any traffic shaping - the shaping is done by the CBQ
-# class the SFQ is attached to.
-#
-# QUANTUM=<bytes>				optional, default not set
-#
-#	This parameter should not be set lower than link MTU, for ethernet
-#	it is 1500b, or (with MAC header) 1514b which is the value used
-#	in Alexey Kuznetsov's examples.
-#
-# PERTURB=<seconds>				optional, default "10"
-#
-#	Period of hash function perturbation. If unset, hash reconfiguration
-#	will never take place which is what you probably don't want. The
-#	default value of 10 seconds is probably a good one.
-#
-### Filter parameters
-#
-# RULE=[[saddr[/prefix]][:port[/mask]],][daddr[/prefix]][:port[/mask]]
-#
-#	These parameters make up "u32" filter rules that select traffic for
-#	each of the classes. You can use multiple RULE fields per config.
-#
-#	The optional port mask should only be used by advanced users who
-#	understand how the u32 filter works.
-#
-# Some examples:
-#
-#	RULE=10.1.1.0/24:80
-#		selects traffic going to port 80 in network 10.1.1.0
-#
-#	RULE=10.2.2.5
-#		selects traffic going to any port on single host 10.2.2.5
-#
-#	RULE=10.2.2.5:20/0xfffe
-#		selects traffic going to ports 20 and 21 on host 10.2.2.5
-#
-#	RULE=:25,10.2.2.128/26:5000
-#		selects traffic going from anywhere on port 50 to
-#		port 5000 in network 10.2.2.128
-#
-#	RULE=10.5.5.5:80,
-#		selects traffic going from port 80 of single host 10.5.5.5
-#
-#
-#
-# REALM=[srealm,][drealm]
-#
-#	These parameters make up "route" filter rules that classify traffic
-#	according to packet source/destination realms. For information about
-#	realms, see Alexey Kuznetsov's IP Command Reference. This script
-#	does not define any realms, it justs builds "tc filter" commands
-#	for you if you need to classify traffic this way.
-#
-#	Realm is either a decimal number or a string referencing entry in
-#	/etc/iproute2/rt_realms (usually).
-#
-# Some examples:
-#
-#	REALM=russia,internet
-#		selects traffic going from realm "russia" to realm "internet"
-#
-#	REALM=freenet,
-#		selects traffic going from realm "freenet"
-#
-#	REALM=10
-#		selects traffic going to realm 10
-#
-#
-#
-# MARK=<mark>
-#
-#	These parameters make up "fw" filter rules that select traffic for
-#	each of the classes accoring to firewall "mark". Mark is a decimal
-#	number packets are tagged with if firewall rules say so. You can
-#	use multiple MARK fields per config.
-#
-#
-# Note: Rules for different filter types can be combined. Attention must be
-#	paid to the priority of filter rules, which can be set below using
-#	PRIO_{RULE,MARK,REALM} variables.
-#
-### Time ranging parameters
-#
-# TIME=[<dow>,<dow>, ...,<dow>/]<from>-<till>;<rate>/<weight>[/<peak>]
-# TIME=0,1,2,5/18:00-06:00;256Kbit/25Kbit
-# TIME=60123/18:00-06:00;256Kbit/25Kbit
-# TIME=18:00-06:00;256Kbit/25Kbit
-#
-#	This parameter allows you to differentiate the class bandwidth
-#	throughout the day. You can specify multiple TIME parameters, if
-#	the times overlap, last match is taken. The fields <rate>, <weight>
-#	and <peak> correspond to parameters RATE, WEIGHT and PEAK (which
-#	is optional and applies to TBF leaf qdisc only).
-#
-#	You can also specify days of week when the TIME rule applies. <dow>
-#	is numeric, 0 corresponds to sunday, 1 corresponds to monday, etc.
-#
-###
-#
-# Sample configuration file: cbq-1280.My_first_shaper
-#
-# --------------------------------------------------------------------------
-# DEVICE=eth0,10Mbit,1Mbit
-# RATE=128Kbit
-# WEIGHT=10Kbit
-# PRIO=5
-# RULE=192.128.1.0/24
-# --------------------------------------------------------------------------
-#
-# The configuration says that we will control traffic on 10Mbit ethernet
-# device eth0 and the traffic going to network 192.168.1.0 will be
-# processed with priority 5 and shaped to rate of 128Kbit.
-#
-# Note that you can control outgoing traffic only. If you want to control
-# traffic in both directions, you must set up CBQ for both interfaces.
-#
-# Consider the following example:
-#
-#                    +---------+      192.168.1.1
-# BACKBONE -----eth0-|  linux  |-eth1------*-[client]
-#                    +---------+
-#
-# Imagine you want to shape traffic from backbone to the client to 28Kbit
-# and traffic in the opposite direction to 128Kbit. You need to setup CBQ
-# on both eth0 and eth1 interfaces, thus you need two config files:
-#
-# cbq-028.backbone-client
-# --------------------------------------------------------------------------
-# DEVICE=eth1,10Mbit,1Mbit
-# RATE=28Kbit
-# WEIGHT=2Kbit
-# PRIO=5
-# RULE=192.168.1.1
-# --------------------------------------------------------------------------
-#
-# cbq-128.client-backbone
-# --------------------------------------------------------------------------
-# DEVICE=eth0,10Mbit,1Mbit
-# RATE=128Kbit
-# WEIGHT=10Kbit
-# PRIO=5
-# RULE=192.168.1.1,
-# --------------------------------------------------------------------------
-#
-# Pay attention to comma "," in the RULE field - it denotes source address!
-#
-# Enjoy.
