For an Ethernet connection, this script is best called right after the interface is configured. This is done by adding <literal>up</literal> and <literal>down</literal> directives to the <filename>/etc/network/interfaces</filename> file allowing declared commands to be run, respectively, after the interface is configured and before it is deconfigured. For example:

The main purpose of <command>wondershaper</command> (in the similarly-named package) is to minimize latencies independent of network load. This is achieved by limiting total traffic to a value that falls just short of the link saturation value.
<command>wondershaper</command> (在同名的软件包中) 的主要目的是最小化独立网络负载的延迟。经由限制整体流量的值缩短链接的饱和值。

Once a network interface is configured, setting up this traffic limitation is achieved by running <command>wondershaper <replaceable>interface</replaceable> <replaceable>download_rate</replaceable> <replaceable>upload_rate</replaceable></command>. The interface can be <literal>eth0</literal> or <literal>ppp0</literal> for example, and both rates are expressed in kilobits per second. The <command>wondershaper remove <replaceable>interface</replaceable></command> command disables traffic control on the specified interface.
配置网络接口后,运行 <command>wondershaper <replaceable>interface</replaceable> <replaceable>download_rate</replaceable> <replaceable>upload_rate</replaceable></command>命令,设置流量控制。可以是 <literal>eth0</literal> 或 <literal>ppp0</literal> 接口,两者的速度均以每秒千位为单位。<command>wondershaper remove <replaceable>interface</replaceable></command> 命令可以在特定接口停用流量控制。

For an Ethernet connection, this script is best called right after the interface is configured. This is done by adding <literal>up</literal> and <literal>down</literal> directives to the <filename>/etc/network/interfaces</filename> file allowing declared commands to be run, respectively, after the interface is configured and before it is deconfigured. For example:

Changes in the <filename>/etc/network/interfaces</filename> file
185

iface eth0 inet dhcp
up /sbin/wondershaper eth0 500 100
down /sbin/wondershaper remove eth0
186
In the PPP case, creating a script that calls <command>wondershaper</command> in <filename>/etc/ppp/ip-up.d/</filename> will enable traffic control as soon as the connection is up.

The <filename>/usr/share/doc/wondershaper/README.Debian.gz</filename> file describes, in some detail, the configuration method recommended by the package maintainer. In particular, it advises measuring the download and upload speeds so as to best evaluate real limits.
