Institut für Verteilte Systeme

Unser Institut beschäftigt sich mit Themen wie Skalierbarkeit, Zuverlässigkeit, Sicherheit und Datenschutz, Selbstorganisation und Beherrschbarkeit von Komplexität in Verteilten Systemen in einer Vielzahl von Einsatzszenarien wie Cloud-Computing oder Fahrzeug-Fahrzeug-Kommunikation.

In der Lehre decken wir das gesamte Spektrum von Rechnernetzen, über verteilte Systeme bis hin zu Sicherheit und Privacy-Schutz ab.

Virtual Nodes: a re-configurable replication framework for highly-available grid services
Proceedings of the ACM/IFIP/USENIX Middleware'08 Conference Companion , Seite 107--109.
Herausgeber: ACM New York, NY, USA,

Zusammenfassung: We present Virtual Nodes, a framework to provide fault-tolerance for grid applications by replicating them over multiple nodes. For the performance of replicated systems it is crucial that the application characteristics and load pattern are taken into account when the replication protocol is selected. For that reason Virtual Nodes offer a wide variety of configuration parameters that allow to fine-tune framework properties to optimise the overall system performance.

Personalizable ambient fixture
Intelligent Environments, 2008 IET 4th International Conference on , Seite 1--7.

Zusammenfassung: Ambient displays provide us with information in the background of our awareness. However, as each user has individual wishes and needs of how, which and when information is presented, the acceptance of ambient displays is low. In this paper we introduce an abstract output facility which provides personalization for ambient fixtures. We employ a notification system to enhance the capability of a fixture to display more than one variable. We evaluate our concept within a dual task experiment in comparison to preset notifications. The results show a level of self-interruption which is significantly lower than using preset notifications. Therefore our approach outperforms preset notifications and moves ambient displays closer to secondary displays in human-computer interaction.
