# tc4shorewall Version 0.5

# /etc/shorewall/tcclasses
#
# Define the classes used for traffic shaping in this file.
#
# A note on the rate/bandwidth definitions used in this file:
#
# - don't use a space between the integer value and
# the unit: 30kbit is valid while 30 kbit is NOT.
#
# - you can use one of the following units:
#
# kbps Kilobytes per second
# mbps Megabytes per second
# kbit Kilobits per second
# mbit Megabits per second
# bps or a
# bare number Bytes per second
#
# - if you want the values to be calculated for you depending
# on the output bandwidth setting defined for an interface
# in tcdevices, you can use expressions like the following:
#
# full/3 causes the bandwidth to be calculated
# as 3 of the the full outgoing
# speed that is defined.
#
# full*9/10 will set this bandwidth to 9/10 of
# the full bandwidth
#
# DO NOT add a unit to the rate if it is calculated !
#
# Columns are:
#
# INTERFACE Name of interface. Each interface may be listed only
# once in this file. You may NOT specify the name of
# an alias (e.g., eth0:0) here; see
# http://www.shorewall.net/FAQ.htm#faq18
#
# You man NOT specify wildcards here, e.g. if you
# have multiple ppp interfaces, you need to put
# them all in here!
#
# Please note that you can only use interface names
# in here that have a bandwidth defined in the tcdevices
# file
#
# MARK The mark value which is an integer in the range 1-255.
# You define this marks in the tcrules file, marking
# the traffic you want to fit in the classes defined
# in here.
#
# You can use the same marks for different Interfaces
#
# RATE The minimum bandwidth this class should get,
# when the traffic load rises. Please note
# that first the classes which equal or a lesser priority
# value are served.
#
# You can use the following
#Use kbit or kbps(for Kilobytes per second) for
# speed, and make sure there is NO space between the
# number and the unit.
#
# CEIL The maximum bandwidth this class is allowed to use
# when the link is idle. Useful if you have traffic
# which can get full speed when more needed services
# (e.g. ssh) are not used.
#
# You can use the value "full" in here for setting
# the maximum bandwidth to the defined output bandwidth
# of that interface
#
# Use kbit or kbps(for Kilobytes per second) for
# speed, and make sure there is NO space between the
# number and the unit.
#
# PRIORITY you have to define a priority for the class
# Packages in a class with a higher priority (=lesser value)
# are handled before lesser priority onces.
# You can just define the mark value here also, if you are
# increasing the mark values with lesser priority.
#
# OPTIONS A comma-separated list of options including the
# following:
#
# default - this is the default class for that
# interface where all traffic should go,
# that is not classified otherwise.
#
# NOTE: defining default for exactly one
# class per interface is mandatory!
#
# tos-<tosname> - this lets you define a filter for
# the given <tosname> which lets you
# define a value of the Type Of Service
# bits in the ip package which causes
# the package to go in this class.
# Please note, that this filter overrides
# all mark settings, so if you define
# a tos filter for a class all traffic
# having that mark will go in it regard-
# less of the mark on the package.
# You can use the following
# for this option
#
# tos-minimize-delay (16)
# tos-maximize-throughput (8)
# tos-maximize-reliability (4)
# tos-minimize-cost (2)
# tos-normal-service (0)
#
# NOTE: each of this options is only
# valid for ONE class per interface.
#
# tcp-ack - if defined causes an tc filter to
# be created that puts all tcp ack
# packets on that interface that have
# an size of <=64 Bytes to go in this
# class. This is useful for speeding up
# downloads. Please note that the size
# of the ack packages is limited to 64
# bytes as some applications (p2p for
# example) use to make every package an
# ack package which would cause them
# all into here. We want only packages
# WITHOUT payload to match, so the size
# limit.
#
# NOTE: This option is only valid for
# ONE class per interface.
#
#
#
# Example 1: Suppose you are using PPP over Ethernet (DSL)
# and ppp0 is the interface for this. The
# device has an outgoing bandwidth of 500kbit.
# You have 3 classes here, the first you can use for
# interactive traffic (ssh) the second for p2p networking
# and the last one the rest. They all have a guaranteed
# bandwidth of 100kbit upstream, but 1 and 3 can get
# full speed if link is idle, 2 is limited to 200kbit
#
# ppp0 1 100kbit full 1 tcp-ack,tos-minimize-delay
# ppp0 2 100kbit 200kbit 2
# ppp0 3 full/3 full/2 3 default
