Enabling Cloud Connectivity Using SDN and NFV Technologies

Cloud environments play an important role for network and service providers. Cloud network providers require ubiquitous, broadband and minimum-delay connectivity from network providers. There are different realizations of cloud connectivity based on the Software Defined Networking (SDN) and the Network Function Virtualization (NFV) paradigm. In this paper we introduce a new concept based on the OConS architecture developed within the SAIL FP7 project. Our advanced connectivity concept focuses on interdomain connectivity.
