The evolution of the Internet in the last few years has been characterized by dramatic changes to the way users behave, interact and utilize the network.

The rapid introduction of new categories of applications such as network games and peer-to-peer, the increasing presence of malicious traffic, and the widespread use of encryption techniques, make the measurement, analysis and classification of Internet traffic a challenging task.

The research community and many network operators are responding to these changes by designing and deploying traffic measurement and classification architectures of increasing complexity.

Such activities are pivotal for researchers, developers, service managers and providers, as well as for end users involved in the evolution of the networks.

Traffic classification and analysis mechanisms belong to the wide set of tools that helps the allocation, control and management of resources in IP networks. Following the development and the evolution of Internet applications, new efficient classification techniques are highly desirable to support advanced capabilities as regards network monitoring, network resource management, anomaly detection, and network auditing.

This workshop is intended to serve as a forum for scientists and engineers in academia and industry to exchange and discuss their experiences and research results about all aspects of traffic classification and analysis.
