5 Packet Classification and Labelling
Introduction This chapter will explain in detail how packets are classified. This classification is
configured via rules in a packet filter mechanism.
When a packet hits a rule, it will be marked with the label that is associated with this
rule. Like this, packets with certain properties can be given a common name.
Next to the name of the label, also some parameters are linked to the packet(s).
These parameters can be QoS values, priorities and actions like ToS marking etc.
