Challenges of an information model for federating virtualized infrastructures

Users of the Future Internet will expect seamless and secure access to virtual resources distributed across multiple domains. These federated platforms are the core of the Future Internet. It is clear that information models, and concrete implementation in data models, are necessary prerequisites for all federative operations, information exchanges, and service support. This position paper describes our approach to the development of an information model for federating virtual infrastructures. Our basic assumption is that semantic resource descriptions with context-awareness, in the form of Semantic Web descriptions, better support services in federated platforms. We use our experiences in the development of two ontologies for computer networks and for network monitoring, NDL and MOMENT, to support and guide our development. The requirements of our envisaged Information and Data models are driven from a concrete use-case, using PlanetLab and FEDERICA as examples of virtualized platforms in a Future Internet federated environment.
