Opis: Reliable Distributed Systems in OCaml

Viktor Kuncak, Dejan Kostic, Pierre-Evariste Dagand

Concurrency and distribution pose algorithmic and implementation challenges in developing reliable distributed systems, making the field an excellent testbed for evaluating programming language and verification paradigms. Several specialized domain-specifi ...

Utility-based Packet Scheduling in P2P Mesh-based Multicast

Pascal Frossard

We consider streaming video content over an overlay network of peer nodes. We propose a novel streaming strategy that is built on utility-based packet scheduling and proportional resource sharing in order to fight against free- riders. Each of the peers em ...

Game Theory Video Streaming

Mahdad Hosseini Kamal

We consider the problem of peer selection for multimedia trans- mission over a peer-to-peer (P2P) network to find a strategy model for peer selection for each lost packet. Our problem consists of two parts one related to the P2P network that is a peer sele ...

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 ...

CrystalBall: Predicting and Preventing Inconsistencies in Deployed Distributed Systems

Viktor Kuncak, Dejan Kostic, Maysam Yabandeh, Nikola Knezevic

We propose a new approach for developing and deploying distributed systems, in which nodes predict distributed consequences of their actions, and use this information to detect and avoid errors. Each node continuously runs a state exploration algorithm 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 ...

Diffusion Least-Mean Squares Over Adaptive Networks: Formulation and Performance Analysis

Ali H. Sayed

We formulate and study distributed estimation algorithms based on diffusion protocols to implement cooperation among individual adaptive nodes. The individual nodes are equipped with local learning abilities. They derive local estimates for the parameter o ...

Adaptive Load Sharing for Network Processors

Jean-Yves Le Boudec

A novel scheme for processing packets in a router is presented that provides load sharing among multiple network processors distributed within the router. It is complemented by a feedback control mechanism designed to prevent processor overload. Incoming t ...

Distributed optimization of media flows in peer-to-peer overlay networks

We consider the problem of rate-distortion (RD) optimized media streaming in unstructured peer-to-peer (P2P) overlay networks. We formulate the aforementioned problem as a distributed rate allocation problem. To solve the problem for all the participating ...

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 ...
