Show/Hide Abstract Simulator Development - Annual Report Year 3 (2007)
Werner Streitberger Torsten Eymann Floriano Zini Björn Schnizler Hong Tuan Kiet Vo
This document describes the progress of the simulator development with in the third year of the CATNETS project. The refinement of the simulator as well as a detailed guide to conducting simulations is presented.
Show/Hide Abstract CATNETS Final Activity Report (2007)
Werner Streitberger Torsten Eymann
This paper presents the final activity report of the CATNETS project. It summarizes the project objectives, the contractors involved, the work performed and the final results. A description of the dissemination activities concludes the report.
Show/Hide Abstract A Theoretical and Computational Basis for CATNETS (2006)
Björn Schnizler Dirk Neumann Daniel Veit Michael Reinicke Werner Streitberger Torsten Eymann Felix Freitag Isaac Chao Pablo Chacin
The main content of this report is the identification and definition of market mechanisms for Application Layer Networks (ALNs). On basis of the structured Market Engineering process, the work comprises the identification of requirements which adequate market mechanisms for ALNs have to fulfill. Subsequently, two mechanisms for each, the centralized and the decentralized case are described in this document. These build the theoretical foundation for the work within the following two years of the CATNETS project.
Show/Hide Abstract Environmental Analysis for Application Layer Networks (2005)
Björn Schnizler Dirk Neumann Daniel Veit Mauro Napoletano Michele Catalano Mauro Gallegati Michael Reinicke Werner Streitberger Torsten Eymann
Die zunehmende Vernetzung von Rechners über das Internet lies die Vision von Application Layer Netzwerken aufkommen. Sie umfassen Overlay Netzwerke wie beispielsweise Peer-to-Peer Netzwerke und Grid Infrastrukturen unter Verwendung des TCP/IP Protokolls. Ihre gemeinsame Eigenschaft ist die redundante, verteilte Bereitstellung und der Zugang zu Daten-, Rechen- und Anwendungsdiensten, während sie die Heterogenität der Infrastruktur vor dem Nutzer verbergen. In dieser Arbeit werden die Anforderungen, die diese Netzwerke an ökonomische Allokationsmechanismen stellen, untersucht. Die Analyse erfolgt anhand eines Marktanalyseprozesses für einen zentralen Auktionsmechanismus und einen katallaktischen Markt.
Show/Hide Abstract A Scalability Analysis of Grid allocation Mechanisms (2008)
Michael Reinicke Werner Streitberger Torsten Eymann
This article examines the broker´s behavior with regard to a varying number of participating nodes and shows that incremental losses have to be accepted in central resource allocation when introducing new nodes.
Show/Hide Abstract Theoretical and Computational Basis for CATNETS - Annual Report Year 2 (2006)
Torsten Eymann Werner Streitberger Daniel Veit Georg Buss Björn Schnizler Dirk Neumann
In this work the self-organising potential of the CATNETS allocation mechanism is described to provide a more comprehensive view on the research done in this project. The formal description of either the centralised and decentralised approach is presented. Furthermore the agents’ bidding model is described and a comprehensive overview on how the catallactic mechanism is incorporated into the middleware and simulator environments is given.
Show/Hide Abstract Preliminary specification and design documentation for software components to achieve Catallaxy in computational systems (2005)
Torsten Eymann Werner Streitberger Michael Reinicke Felix Freitag Pablo Chacin Isaac Chao Björn Schnizler Daniel Veit
Die Arbeit beschreibt die Spezifikation und das Design von Softwarekomponenten, um das Konzept der Katallaxie in Grid Systemen umzusetzen. Eine Einführung ordnet das Konzept der Katallaxie in bestehende Grid Taxonomien ein und stellt grundlegende Komponenten vor. Anschließend werden diese Komponenten auf ihre Anwendbarkeit in bestehenden Application Layer Netzwerken untersucht.
Show/Hide Abstract Analysis of Simulation Environment (2005)
Torsten Eymann Michael Reinicke Werner Streitberger Floriano Zini Gianfranco Giulioni
In this paper the requirements for an ALN simulation environment are analysed, as needed in the CATNETS Project. A number of grid and general purpose simulators are evaluated regarding the identified requirements for simulating economical resource allocation mechanisms in ALNs. Subsequently a suitable simulator is chosen for usage in the CATNETS project.
Show/Hide Abstract Theoretical and Computational Basis for Economical Ressource Allocation in Application Layer Networks -Annual Report Year 1 (2005)
Torsten Eymann Michael Reinicke Werner Streitberger Björn Schnizler Daniel Veit Felix Freitag Isaac Chao Pablo Chacin Dirk Neumann
This paper identifies and defines suitable market mechanisms for Application Layer Networks (ALNs). On basis of the structured Market Engineering process, the work comprises the identification of requirements which adequate market mechanisms for ALNs have to fulfill. Subsequently, two mechanisms for each, the centralized and the decentralized case are described in this document.5
Show/Hide Abstract A Policy Framework including Trust and Reputation in Grid Environments (2007)
Torsten Eymann Raimund Matros Stefan König
This paper examines the role of policies in different grid environments. A Grid technology becomes standardized and stable, various business models are envented and increasingly applied, and economic implications can be observed.Asymmetrically distributed information may allow for opportunistic behaviour of service providers or users who exploit the information gap between providers and consumers on the quality of services.
