Netbench: Framework for Evaluation of Packet Processing Algorithms

Many algorithms and hardware architectures are proposed to increase processing speed of time-critical operations in the field of longest prefix matching, packet classification and regular expression matching. Despite this fact, there is still no free and easily extensible platform for evaluation, comparison and experiments with existing approaches. We propose the Net bench Framework which aims to serve as an independent platform for researchers seeking the easiest way to implement their algorithms, as well as the comparison of their algorithms with reference implementations of other approaches. The framework is provided as an open source and can be easily extended to support new algorithms or new comparison methodology. Net bench is publicly available at http://www.fit.vutbr.cz/netbench.
