Many traffic analysis tasks are solved with tools that are developed in an ad-hoc, incremental, and cumbersome way instead of seeking systematic solutions that are easy to reuse and understand. The huge amount of data that has to be managed and analyzed together with the fact that many different analysis tasks are performed over a small set of different network trace formats, motivates us to study whether Data Stream Management Systems (DSMSs) might be useful to develop traffic analysis tools. We have performed an ex-perimental study to analyze the advantages and limitations of using DSMS in practice. We study how simple and complex analysis tasks can be solved with TelegraphCQ, a public domain DSMS, and present a preliminary performance analysis.
