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 ...

Optimal Scheduling of Peer-to-Peer File Dissemination

Jochen Mundinger

Peer-to-peer (P2P) overlay networks such as BitTorrent and Avalanche are increasingly used for disseminating potentially large files from a server to many end users via the Internet. The key idea is to divide the file into many equally-sized parts and then ...

Query-load balancing in structured overlays

Karl Aberer, Anwitaman Datta, Roman Schmidt

Query-load (forwarding and answering) balancing in structured overlays is one of the most critical and least studied problems. It has been assumed that caching heuristics can take care of it. We expose that caching, while necessary, is not in itself suffic ...

Gossip-Based Peer Sampling

Rachid Guerraoui, Anne-Marie Kermarrec

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: ...

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 ...

SoS: self-organizing substrates

Anwitaman Datta

Large-scale networked systems often, both by design or chance exhibit self-organizing properties. Understanding self-organization using tools from cybernetics, particularly modeling them as Markov processes is a first step towards a formal framework which ...

Congestion Control for Distributed Hash Tables

Jean-Yves Le Boudec, Karl Aberer, Fabius Klemm

Distributed Hash Tables (DHTs) provide a scalable mechanism for mapping identifiers to socket addresses. As each peer in the network can initiate lookup requests, a DHT has to process concurrently a potentially very large number of requests. In this paper, ...

Peer-to-Peer Applications Beyond File Sharing: Overlay Network Requirements and Solutions

In this paper we analyze the functional and non-functional requirements of peer-to-peer (P2P) systems that go beyond the needs of the well explored file-sharing P2P systems. Four basic subcategories are suggested to classify the non-functional requirements ...

The challenges of merging two similar structured overlays: A tale of two networks

Karl Aberer, Anwitaman Datta

Structured overlay networks is an important and interesting primitive that can be used by diverse peer-to-peer applications. Multiple overlays can result either because of network partitioning or (more likely) because different groups of peers build such o ...

Distributed Media Rate Allocation in Overlay Networks

Pascal Frossard, Dan Jurca

We address the problem of distributed path selection and rate allocation for media streaming in overlay networks. Under the assumption that each node has only a local view of the network, we propose a distributed algorithm for joint path selection, and rat ...
