Most existing Virtual Network (VN) provisioning approaches assume a single administrative domain and therefore, VN deployments are limited to the geographic footprint of the substrate provider. To enable wide-area VN provisioning, network virtualization architectures need to address the intricacies of inter-domain aspects, i.e., how to provision VNs with limited control and knowledge of any aspect of the physical infrastructure. To this end, the authors present a framework for large-scale VN provisioning. They decompose VN provisioning into multiple steps to overcome the implications of limited information on resource discovery and allocation.
