A Case for Overlays in DCN Virtualization
Server virtualization has brought about tremendous value to a modern computing landscape and in particular to data center and cloud infrastructures. Virtual server deployments have become ubiquitous in many development and production sites, in cloud infrastructures and in disaster recovery solutions. Network connectivity is a vital aspect of modern computing. In this paper, the authors explore the new requirements the server virtualization brings to the networking world and show how these requirements are different from those of physical server connectivity.
