Abstract BGP data contains artifacts introduced by the measurement infrastructure which can substantially affect analysis. This is especially important in operational systems where ldquocrying wolfrdquo will result in an operator ignoring alarms. In this paper, we investigate the causes of measurement artifacts in BGP data – cross-checking and using properties of the data to infer the presence of an artifact and minimize its impact. We have developed a prototype tool, CleanBGP, which detects and corrects the effects of artifacts in BGP data, which we believe should be used prior to the analysis of such data. CleanBGP provides the user with an understanding of the artifacts present, a mechanism to remove their effects, and consequently the limitations of results can be fully quantified.
