Service selection is an important issue for market-oriented Grid infrastructures. However, few results have been published on the use and evaluation of market models in deployed prototypes, making it difficult to assess their capabilities. In this paper we study the integration of an extended version of Zero Intelligence Plus (ZIP) agents in a midd...

... a SOG infrastructure, the GMM is exposed to be accessed by applications trough a convenient access point, a Web Service which can be deployed in any application server and integrated as a service in an existent SOG. Figure 3 de- scribes the main steps in the interaction trough the access point. When a client issues a request, the application determines which Grid services are required to fulfill it. ...

... Since standard Grid middleware does not provide all the infrastructure services necessary for an open marketplace, on Layer 1 the available information of standard Grid middleware is augmented by additional infrastructure services including real-time logging, market information (historical information about former transactions) and market directory (current information about resources, prices etc.) For more details on the implemented SLAs we refer the reader to [5, 8, 17]. The security management component on Layer 3 is intended as the entry point for a single sign-on mechanism and is responsible for a tamper-proof identity management for the consumers, the suppliers and the constituent components of the SORMA system. ...
Economic mechanisms enhance technological solutions by setting the right incentives to reveal information about demand and supply accurately. Market or pricing mechanisms are ones that foster information exchange and can therefore attain ecient allocation. By assigning a value (also called utility) to their service requests, users can reveal their relative urgency or costs to the service. The implementa- tion of theoretical sound models induce further complex challenges. The EU-funded project SORMA analyzes these challenges and provides a prototype as a proof-of-concept. In this paper the approach within the SORMA-project is described on both conceptual and technical level.
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.
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.
