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.

Proof-of-Concept Application - Annual Report Year 3 (2007)

Oscar Ardaiz Pablo Chacin Isaac Chao Felix Freitag Leandro Navarro Liviu Joita Omer F. Rana Werner Streitberger Sebastian Hudert Torsten Eymann

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.

Performance Evaluation - Annual Report Year 3 (2007)

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.

Evaluation and Metrics Framework (2005)

Michele Catalano Gianfranco Giulioni Werner Streitberger Michael Reinicke Torsten Eymann

In this paper a metrics framework for evaluating different scenarios in the CATNETS project is defined. The aim is to use this framework to compare the catallactic scenario against the central auctioneer.

Analysis of current middleware in peer-to-peer and grid implementations for enhancement by catallactic mechanisms (2005)

Pablo Chacin Isaac Chao Felix Freitag

Die Arbeit definiert Anforderungen an Grid und Peer-to-Peer Middleware Architekturen und analysiert diese auf ihre Eignung für die prototypische Umsetzung der Katallaxie. Eine Middleware-Architektur für die Umsetzung der Katallaxie in Application Layer Netzwerken wird vorgestellt.

Proof-of-Concept Application - Annual Report Year 1 (2005)

Torsten Eymann Oscar Ardaiz Pablo Chacin Isaac Chao Juan Carlos Cruellas Felix Freitag Manuel Medina Leandro Navarro Miguel Valero Omer Rana Liviu Joita

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.

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.

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
