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...

This deliverable describes the work done in the first 6 months of task 2.1, " Software components:Specification and design of software components, based on theoretical and experimentalexperience from related and the assessment projects, so that Catallaxy can be implementedin any computational...

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...

Grid computing has recently become an important paradigm for managing eomputationally demanding applications (composed of a collection of services). Providing dynamic discovery of services, and the determination of a service with the "best value" remains a complex problem in Grid computing. Such...

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...
