Virtual network embedding in software-defined networks [PDF]
NOMS 2016 - 2016 IEEE/IFIP Network Operations and Management Symposium, 2016 Research on network virtualization has been active for a number of years, during which a number of virtual network embedding (VNE) approaches have been proposed. These approaches, however, neglect important operational requirements imposed by the underlying virtualization platforms. In the case of SDN/OpenFlow-based virtualization, a crucial example of

On the Hardness and Inapproximability of Virtual Network Embeddings [PDF]
IEEE/ACM Transactions on Networking, 2020 Many resource allocation problems in the cloud can be described as a basic Virtual Network Embedding Problem (VNEP): the problem of finding a mapping of a request graph (describing a workload) onto a substrate graph (describing the physical infrastructure).
