Vertrauensbildende Maßnahmen in Grid-Ökonomien
(2007)
- Mit zunehmender Verbreitung von Grid-Infrastrukturen in Unternehmen gewinnt die Frage nach Vertrauen immer mehr an Bedeutung. In einer offenen, heterogenen, sich ständig verändernden Umgebung, wie z.B. der Grid-Ökonomie ist hundertprozentige Sicherheit nicht zu gewährleisten; aus diesem Grund ist Vertrauen in den Handelspartner notwendig. Ziel dieser Arbeit ist es, bereits bestehende vertrauensbildende Maßnahmen aus dem Bereich der Informationsökonomie bezüglich ihrer Übertragbarkeit auf GridÖkonomien kritisch zu analysieren. Dabei sollen ausgewählte Instrumente zur Überwindung von Unsicherheit durch Informationsbereitstellung vorgestellt und diese jeweils anschließend auf ihre Anwendbarkeit in Grid-Ökonomien untersucht werden.

Theoretical and Computational Basis for Economical Ressource Allocation in Application Layer Networks -Annual Report Year 1
(2005)
- 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

Theoretical and Computational Basis for CATNETS - Annual Report Year 2
(2006)
- 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.

Simulator Development - Annual Report Year 2
(2006)
- 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.

Proof-of-Concept Application - Annual Report Year 3
(2007)
- In this report the progress of developing the proof-of-concept application in the CATNETS project is presented. Hence the development of the necessary performance measuring components as well as a distributed application to execute on economic-enhanced Grid/P2P platforms and middleware integration are described.

Proof-of-Concept Application - Annual Report Year 1
(2005)
- In this document the Cat-COVITE Application for use in the CATNETS Project is introduced and motivated. Furthermore an introduction to the catallactic middleware and Web Services Agreement (WS-Agreement) concepts is given as a basis for the future work. Requirements for the application of Cat-COVITE with in catallactic systems are analysed. Finally the integration of the Cat-COVITE application and the catallactic middleware is described.

Preliminary specification and design documentation for software components to achieve Catallaxy in computational systems
(2005)
- 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.

Performance Evaluation - Annual Report Year 3
(2007)
- 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.
