There is a growing interest in discovery of internettopology at the interface level. A new generation of highly distributed measurement systemsis currently being deployed. Unfortunately, prior to this thesis, the researchcommunity has not examined the problem of how to perform such measurements efficiently andin a network-friendly manner. In this book, we make several contributions toward that end. First, we show that standard topology discovery methods are quite inefficient,repeatedly probing the same interfaces. This is a concern, because when scaled up, suchmethods will generate so much traffic that they will begin to resemble DDoS attacks. As it isnot unusual for a route tracing monitor to operate in isolation, we next propose and evaluatestrategies for reducing redundancy within a single monitor. We third propose andevaluate Doubletree, a cooperative algorithm that reduces redundancy simultaneously on routers andend systems. Finally, we also provide a generalization of Bloom filters, calledretouched Bloom filters, that permits false negatives in addition to false positives and allows atrade-off between the two.
