Parameters and challenges for Virtual Network embedding in the Future Internet

Abstract

Recent developments in network science will facilitate the Internet as we know it today to integrate existing and upcoming technologies into a heterogeneous and highly dynamic resource pool. This enables the design of new applications and services which will form the Future Internet (FI). From this, many interesting prospects and unknown flexibility in terms of resource usage arise. In order to achieve this flexibility and make it usable for Service Providers (SPs) a key concept of the FI will be Virtual Networks (VNs) embedded into this resource pool. Furthermore, Federation which includes a closer interaction, resource sharing, and information exchange between providers will be an enabler for this freedom of design. This allows the operation of heterogeneous and divergent services on the same physical infrastructure substrate. It is clear to see that all these upcoming possibilities offer new areas of research. In this work we structure the parameters required to describe resources and services accurately. Furthermore, we summarize research questions that need to be resolved in order to make the FI a story of success.
