Performance Evaluation - Annual Report Year 2 (2006)

Oscar Ardaiz Michele Catalano Pablo Chacin Isaac Chao Juan Carlos Cruellas Felix Freitag Manuel Medina Leandro Navarro Miguel Valero Liviu Joita Omer F. Rana Björn Schnizler Torsten Eymann

In this paper a performance measuring infrastructure,developed for the prototype and simulator, concering the experiment configuration, data measurement, and data collection, is presented. A corresponding performance evaluation framework is defined to obtain the metrics from the measured data. Initial experiments were carried out to test the developed prototype, simulator and the performance measuring infrastructure.

Georg Buss Nils Parasie Daniel Veit Michele Catalano Pablo Chacin Isaac Chao Felix Freitag Leandro Navarro Omer F. Rana Liviu Joita Björn Schnizler Werner Streitberger Torsten Eymann

This report describes the work done and results obtained in third year of the CATNETS project. Experiments carried out with the different configurations of the prototype are reported and simulation results are evaluated with the CATNETS metrics framework. The applicability of the Catallactic approach as market model for service and resource allocation in application layer networks is assessed based on the results and experience gained both from the prototype development and simulations.

Simulator Development - Annual Report Year 2 (2006)

Gaetano Calabrese Björn Schnizler Werner Streitberger Torsten Eymann Floriano Zini

In this paper the simulation environment for the CATNETS project is defined further. The chosen simulator is adopted in terms of new features an architecture changes in order to provide a valid simulation environment for Application Layer Network scenarios. Furthermore the requirements for a scenario generator and the needed configuration mechanisms for the actual simulation runs are introduced.

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

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.

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.

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.

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.

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.

Theoretical and Computation Basis for CATNETS - Annual Report Year 3 (2007)

Daniel Veit Georg Buss Björn Schnizler Dirk Neumann Werner Streitberger Torsten Eymann

In this document the developments in defining the computational and theoretical framework for economical resource allocation are described. Accordingly the formal specification of the market mechanisms, bidding strategies of the involved agents and the integration of the market mechanisms into the simulator were refined.
