The increasing interconnection between computers through the Internet has emergedthe vision of Application Layer Networks. Application Layer Networks comprise anabstract view on overlay networks (e.g. Peer-to-Peer networks, Grid infrastructures) ontop of the TCP/IP protocol. Their common...

Considerable efforts have been made developing software architectures which allowclients to obtain service “on demand”. The service-oriented architecture (SOA) based onweb service technologies provides a fundamental concept for this purpose, and is oftenadopted in current Grid implementation...

What makes economics so attractive for computing environments is that its central researchquestion lies in the efficient allocation of resources, provided by suppliers and indemand by customers. In computing environments like Grid Computing, the resourcesin question are processor time or storage...

One of the main issues in the development of future Grid and Peer-to-Peer (P2P) networksystems is the efficient exploitation of services and resources available in the network.A scalable, dynamic, and adaptable allocation mechanism is essential so that quality ofservice requirements from network...

Grid Computing is a paradigmatic application forthe requirements associated with the exponentially growingcomplexity in the engineering, operation and maintenance oftoday’s information systems. Grid Computing comprises evergrowingglobal communication infrastructures and millions ofpossible...

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.

Die zunehmende Vernetzung von Rechnern 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...

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...

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....

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.
