Pagano00aWaterfall: Rapid identification of IP flows using cascade classification3 aIn the last years network traffic classification has attracted much research effort, given that it represents the foundation of many Internet functionalities such as Quality of Service (QoS) enforcement, monitoring, and security. Nonetheless, the proposed works are not able to satisfactorily solve the problem, usually being suitable for only addressing a given portion of the whole network traffic and thus none of them can be considered an ultimate solution for network classification. In this paper, we address network traffic classification by proposing a new architecture-named Waterfall architecture-that, by combining several classification algorithms together according to a cascade principle, is able to correctly classify the whole mixture of network traffic.  a1865-0929
