Another Glance at Double-Length Hashing

We propose a novel framework for blockcipher-based double-length hash functions by extending the recent generalization presented by Stam at FSE '09 for single-call hash functions. We focus on compression functions compressing 3n bits to 2n bits that use on ...

A high-performance distributed hash table for peer-to-peer information retrieval

Fabius Klemm

This thesis describes our research results in the context of peer-to-peer information retrieval (P2P-IR). One goal in P2P-IR is to build a search engine for the World Wide Web (WWW) that runs on up to hundreds of thousands or even millions computers distri ...

Hybrid DHT Design for Mobile Environments

Simon Schubert, Zoran Despotovic

In this paper we present a hybrid design concept for Distributed Hash Tables (DHTs), in order to increase the performance of DHTs in scenarios with mobile participants. By defining two classes of nodes (static and temporary) and assigning critical overlay ...

SONDe, a Self-Organizing Object Deployment Algorithm in Large-Scale Dynamic Systems

Anne-Marie Kermarrec, Vincent Gramoli

We present the design, correctness, and analysis of SONDe, a simple fully decentralized object deployment algorithm for highly requested systems. Given an object (service or data), SONDe provides a node with a constant upper bound (h) on the number of logi ...

Full Functional Verification of Linked Data Structures

Viktor Kuncak

We present the first verification of full functional correctness for a range of linked data structure implementations, including mutable lists, trees, graphs, and hash tables. Specifically, we present the use of the Jahob verification system to verify form ...

UniStore: Querying a DHT-based Universal Storage

Manfred Hauswirth, Roman Schmidt, Renault John Lecoultre, Jessica Müller

The idea of collecting and combining large public data sets and services became more and more popular. The special characteristics of such systems and the requirements of the participants demand for strictly decentralized solutions. However, this comes alo ...

Improving the Throughput of Distributed Hash Tables Using Congestion-Aware Routing

Jean-Yves Le Boudec, Karl Aberer, Dejan Kostic, Fabius Klemm

Advanced applications for Distributed Hash Tables (DHTs), such as Peer-to-Peer Information Retrieval, require a DHT to quickly and efficiently process a large number (in the order of millions) of requests. In this paper we study mechanisms to optimize the ...

On Routing in Distributed Hash Tables

Jean-Yves Le Boudec, Karl Aberer, Fabius Klemm, Sarunas Girdzijauskas

There have been many proposals for constructing routing tables for Distributed Hash Tables (DHT). They can be classified into two groups: A) those that assume that the peers are uniformly randomly distributed in the identifier space, and B) those that allo ...

GridVine: an Infrastructure for Peer Information Management

Karl Aberer, Philippe Cudré-Mauroux

GridVine is a semantic overlay infrastructure based on a peer-to-peer (P2P) access structure. Built following the principle of data independence, it separates a logical layer — in which data, schemas, and schema mappings are managed — from a physical layer ...

Similarity Queries on Structured Data in Structured Overlays

Manfred Hauswirth, Roman Schmidt

Structured P2P systems based on distributed hash tables are a popular choice for building large-scaled data management systems. Generally, they only support exact match queries, but data heterogeneities often demand for more complex query types, particular ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
