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 usecase,
using PlanetLab and FEDERICA as examples of virtualized
platforms in a Future Internet federated environment.
