Gossip-Based Peer Sampling

Gossip-based communication protocols are appealing in large-scale distributed applications such as information dissemination, aggregation, and overlay topology management. This paper factors out a fundamental mechanism at the heart of all these protocols: ...

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 ...

UniStore: Querying a DHT-based Universal Storage

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

In recent time, 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 ...

Self-organizing structured peer-to-peer overlay networks

A peer-to-peer overlay network is a logical network, built on top of a physical network. In contrast to classical client-server distributed architectures, peer-to-peer overlay networks allow location of resources without centralized control. Existing overl ...

Principles of Query-Adaptive Optimal Replication in DHTs

Karl Aberer, Anwitaman Datta, Wolfgang Nejdl

This paper focuses on replication in DHT based structured overlay networks, and presents a theoretical framework for optimal replication in such networks with respect to query frequency. In particular, we determine the optimal replication factor for query- ...

Self-organized construction of distributed access structures: A comparative evaluation of P-Grid and FreeNet

Karl Aberer, Manfred Hauswirth

This paper provides a quantative comparison of the efficiency of the self-organized construction processes of the P-Grid and FreeNet peer-to-peer systems. Starting from a defined, realistic network topology we simulate the construction of their access stru ...

Bullet: high bandwidth data dissemination using an overlay mesh

Dejan Kostic

In recent years, overlay networks have become an effective alternative to IP multicast for efficient point to multipoint communication across the Internet. Typically, nodes self-organize with the goal of forming an efficient overlay tree, one that meets pe ...

A generic architecture for VPN configuration management

Jean-Pierre Hubaux

This paper describes the specification of a management architecture allowing virtual private network (VPN) customers to dynamically modify the configuration of their VPN. The specification has been structured according to the ODP viewpoints. A special emph ...
