OF.CPP: Consistent Packet Processing for OpenFlow

Dejan Kostic, Marco Canini, Peter Peresini, Maciej Leszek Kuzniar, Nedeljko Vasic

This paper demonstrates a new class of bugs that is likely to occur in enterprise OpenFlow deployments. In particular, step-by-step, reactive establishment of paths can cause network-wide inconsistencies or performance- and space-related inefficiencies. Th ...

Everything You Always Wanted to Know about Synchronization but Were Afraid to Ask

Rachid Guerraoui, Vasileios Trigonakis, Tudor Alexandru David

This paper presents the most exhaustive study of synchronization to date. We span multiple layers, from hardware cache-coherence protocols up to high-level concurrent software. We do so on different types of architectures, from single-socket - uniform and ...

Clock-SI: Snapshot Isolation for Partitioned Data Stores Using Loosely Synchronized Clocks

Willy Zwaenepoel, Sameh Mohamed Elnikety, Jiaqing Du

Clock-SI is a fully distributed protocol that implements snapshot isolation (SI) for partitioned data stores. It derives snapshot and commit timestamps from loosely synchronized clocks, rather than from a centralized timestamp authority as used in current ...

The Bionic DBMS is Coming, but What Will It Look Like?

Frederick Ryan Johnson, Ippokratis Pandis

Software has always ruled database engines, and commodity processors riding Moore's Law doomed database machines of the 1980s from the start. However, today's hardware landscape is very different, and moving in directions that make database machines increa ...

NoDB: Efficient Query Execution on Raw Data Files

Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Ioannis Alagiannis

As data collections become larger and larger, data loading evolves to a major bottleneck. Many applications already avoid using database systems, e.g., scientific data analysis and social networks, due to the complexity and the increased data-to-query time ...

On the Performance of Software Transactional Memory

Aleksandar Dragojevic

The recent proliferation of multi-core processors has moved concurrent programming into mainstream by forcing increasingly more programmers to write parallel code. Using traditional concurrency techniques, such as locking, is notoriously difficult and has ...

AFFINITY: Efficiently Querying Statistical Measures on Time-Series Data

Karl Aberer, Saket Sathe

Computing statistical measures for large databases of time series is a fundamental primitive for querying and mining time-series data [1–6]. This primitive is gaining importance with the increasing number and rapid growth of time series databases. In this ...
