Internet evolution is driven by a continuous stream of new applications, as well as users driving the demand for these services. To keep up with this, a never-stopping research has been transforming the Internet ecosystem over the time. Technological changes/improvements on both protocols (the uptake of IPv6) and network architectures (the adoption of SDN ) introduced new challenges for ASIC designers. In particular, IPv6 and OpenFlow increased the complexity of the rule matching problem, forcing researchers to build new packet classification algorithms able to keep pace with a steady growth of link speed. As a result, despite lots of research has been carried out over the last years, packet classification is still a hot topic.

The availability of small numbers of real rule sets and synthetic ones, generated with tools such as ClassBench, has boosted research in the IPv4 world. In this talk I will present ClassBench-ng, a new open source tool for the generation of synthetic IPv4, IPv6 and OpenFlow 1.0 rule sets showing similar characteristics of real ones. This tool was built upon results of an analysis of rule sets taken from current operational environments with the aim of meeting the requirements of nowadays researchers and boosting the rule matching research as ClassBench has done since ten years ago.

Bio: Jiri Matousek is a Ph.D. student at Faculty of Information Technology, Brno University of Technology. His research is focused on hardware acceleration of network algorithms using FPG As and generation of synthetic data sets for their benchmarking. He also works for CESNET (Czech NREN ) where he is a member of a team that developed COMBO -CG card, the world’s first 100GE capable FPGA -based network interface card.
