Utilizzo di tecniche di virtualizzazione per la creazione di infrastrutture di comunicazione virtuali on-demand

The use of virtualization techniques at variuos levels of a computing system, opens-up to on-demand creation of complex computating systems by gathering resources from a larger pool of shared resources. This approach, today widely used in modern datacenters, favours new scenarios, which are characterized by an efficient usage of the available hardware resources and reduced sensitivity to failures. A similar approach has been recently proposed in the context of computer networks, and it is usually referred to as "network virtualization". In the context of the SFINGI project, the Research Unit at Univ. of Napoli Federico II will carry on the following activities: a) selection of the most suitable virtualization technologies to be used in Software Routers; b) contribution to the definition of an architectural reference model, by including into this general model the possibility of adopting virtualization techniques for building Software Routers, and by taking into account the peculiar requirements deriving from the adoption of heterogenous (both wired and wireless) transmission technologies; c) definition of service models for the creation of geographically distributed communication infrastructures based on "virtual" Software Routers, according to the Infrastructure-as-a-Service paradigm; d) definition of potential use-case scenarios that may be implemented through "virtual" Software Routers.
