Abstract:Traffc repositories with TCP/IP header information are very important for network analysis. Researchers often assume that such repositories reliably represent all traffc that has been flowing over the network; little thoughts are made regarding the consistency of these repositories.
Still, for various reasons, the trafc capturing process may have missed packets. For certain kinds of analysis, for example loss measurements, such inconsistencies may lead to the wrong conclusions. This paper proposes an algorithm to detect such inconsistencies, using the idea of “fake gaps”. A prototype has been developed, and used to test two well-known repositories: the WIDE and Simpleweb repositories. The paper shows that both repositories contain several inconsistencies.
