Netbench

This is a development and community site of the Netbench Framework.

About Netbench

Netbench is a framework for easy evaluation and experiments with packet processing algorithms. The aim of the framework is to serve as independent platform for researchers seeking the easiest way to implement their algorithms, as well as a comparison of their algorithms with reference implementations of the other approaches.

Written in Python, Netbench currently provides framework for experiments with packet classification, pattern matching and longest prefix match (IP lookup) algorithms. In the future, authors intend to add support for experiments with packet header analysis algorithms and flow context management algorithms.

Community

Authors of the Netbench Framework invite researchers to submit patches, new algorithms, datasets, etc. to email address netbench AT fit.vutbr.cz. After review, these patches will be added to the framework.

Publication

Netbench was presented at the ANCS 2011 conference in New York. (bibtex entry)
