Introduction -- Per-Flow Size Measurement -- Per-Flow Cardinality Measurement -- Persistent Spread Measurement.

Sommario/riassunto

This book presents several compact and fast methods for online traffic measurement of big network data. It describes challenges of online traffic measurement, discusses the state of the field, and provides an overview of the potential solutions to major problems. The authors introduce the problem of per-flow size measurement for big network data and present a fast and scalable counter architecture, called Counter Tree, which leverages a two-dimensional counter sharing scheme to achieve far better memory efficiency and significantly extend estimation range. Unlike traditional approaches to cardinality estimation problems that allocate a separated data structure (called estimator) for each flow, this book takes a different design path by viewing all the flows together as a whole: each flow is allocated with a virtual estimator, and these virtual estimators share a common memory space. A framework of virtual estimators is designed to apply the idea of sharing to an array of cardinality estimation solutions, achieving far



better memory efficiency than the best existing work. To conclude, the authors discuss persistent spread estimation in high-speed networks. They offer a compact data structure called multi-virtual bitmap, which can estimate the cardinality of the intersection of an arbitrary number of sets. Using multi-virtual bitmaps, an implementation that can deliver high estimation accuracy under a very tight memory space is presented. The results of these experiments will surprise both professionals in the field and advanced-level students interested in the topic. By providing both an overview and the results of specific experiments, this book is useful for those new to online traffic measurement and experts on the topic.

Sommario/riassunto

Willard Van Orman Quine's work revolutionized the fields of epistemology, semantics and ontology. At the heart of his philosophy are several interconnected doctrines: his rejection of conventionalism and of the linguistic doctrine of logical and mathematical truth, his rejection of the analytic/synthetic distinction, his thesis of the indeterminacy of translation and his thesis of the inscrutability of reference. In this book Edward Becker sets out to interpret and explain these doctrines. He offers detailed analyses of the relevant texts, discusses Quine's views on meaning, reference and knowledge, and shows how Quine's views developed over the years. He also proposes a new version of the linguistic doctrine of logical truth, and a new way of rehabilitating analyticity. His rich exploration of Quine's thought will interest all those seeking to understand and evaluate the work of one of the most important philosophers of the second half of the twentieth century.
