Voronyi . -# v0.1 - First public release -# -# -# 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-. where -# is two-byte hexadecimal number in range <0002-FFFF> (which in fact -# is a CBQ class ID) and 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 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=,[,] mandatory -# DEVICE=eth0,10Mbit,1Mbit -# -# is the name of the interface you want to control -# traffic on, e.g. eth0 -# is the physical bandwidth of the device, e.g. for -# ethernet 10Mbit or 100Mbit, for arcnet 2Mbit -# is tuning parameter that should be proportional to -# . As a rule of thumb: = / 10 -# -# When you have more classes on one interface, it is enough to specify -# [and ] only once, therefore in other files you only -# need to set DEVICE=. -# -### Class parameters -# -# RATE= 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= 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= 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=[/] 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= 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= 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= 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= 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= 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= -# -# 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=[,, ...,/]-;/[/] -# 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 , -# and 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. -# 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.
