Introduction
Network traffic classification refers to grouping network traffic into
classes or categories on the basis of whether the traffic matches user-
defined criteria. Identifying and categorizing traffic into application
classes enables distinct handling for different types of traffic. It is the
foundation for applying the appropriate quality-of-service (QoS) feature
to that traffic [1,2], such as traffic shaping and traffic policing, enabling
the allocation of network resources to deliver optimal performance for
traffic. For example, high-priority traffic can be singled out for special
handling and, thus, helps achieve peak application performance.
