Journal ArticleDOI
OceanStore: an architecture for global-scale persistent storage
John Kubiatowicz,David Bindel,Yan Chen,Steven E. Czerwinski,Patrick Eaton,Dennis Geels,Ramakrishna Gummadi,Sean Rhea,Hakim Weatherspoon,Westley Weimer,Chris Wells,Ben Y. Zhao +11 more
TL;DR: OceanStore monitoring of usage patterns allows adaptation to regional outages and denial of service attacks; monitoring also enhances performance through pro-active movement of data.
Adaptive RED: An Algorithm for Increasing the Robustness of RED's Active Queue Management
TL;DR: This revised version of Adaptive RED, which can be implemented as a simple extension within RED routers, removes the sensitivity to parameters that affect RED’s performance and can reliably achieve a specified target average queue length in a wide variety of traffic scenarios.
Proceedings ArticleDOI
The impact of DHT routing geometry on resilience and proximity
Krishna P. Gummadi,Ramakrishna Gummadi,Steven D. Gribble,Sylvia Ratnasamy,Scott Shenker,Ion Stoica +5 more
TL;DR: The basic finding is that, despite the initial preference for more complex geometries, the ring geometry allows the greatest flexibility, and hence achieves the best resilience and proximity performance.
Journal ArticleDOI
The Ninja architecture for robust Internet-scale systems and services373423
Steven D. Gribble,Matt Welsh,Rob von Behren,Eric Brewer,David E. Culler,Nikita Borisov,Steven E. Czerwinski,Ramakrishna Gummadi,Jason Hill,Anthony D. Joseph,Randy H. Katz,Zhuoqing Morley Mao,S. Ross,Ben Y. Zhao,Robert C. Holte +14 more
TL;DR: The Ninja project as mentioned in this paper is a workstation cluster environment with a software platform that simplifies scalable service construction, including base stations, units, services, and active proxies, which are transformational elements that are used for unit-or service-specific adaptation.
Journal ArticleDOI
Interference-aware fair rate control in wireless sensor networks
TL;DR: Interferenceaware fair rate control (IFRC) detects incipient congestion at a node by monitoring the average queue length, communicates congestion state to exactly the set of potential interferers using a novel low-overhead congestion sharing mechanism, and converges to a fair and efficient rate using an AIMD control law.
