Design a virtualized enterprise network

This sample chapter from Network Virtualization defines the technical requirements needed to virtualize a network. Then, based on these requirements, it looks at the architectural framework required to successfully support concurrent virtual networks (VNs) over a shared enterprise physical network. The chapter also discusses the importance of maintaining functionality in three areas: transport virtualization, edge authorization, and central services access (VN perimeter). The chapter covers how these functional blocks interface with each other and emphasizes the importance of balancing possible short-term losses in network resiliency and performance against the long-term benefits of network virtualization.
