Module: Filter
This module performs the traffic classification and is based on the
Netfilter framework. The module has several configuration files,
which makes it more flexible to design and develop a site-policy. An
example of a specific site-policy for our real-world setup is
presented in the thesis in Chapter 9, which shows the use of
scheme and filter rules configuration files.
When changing a filter rule the hole scheme configuration does
not need to be reloaded. It is possible to load and unload
individual rules configuration files.
