Network virtualization: The missing piece

current service platforms or frameworks, e.g., Cloud solutions, do not take the infrastructure, necessary for the execution of the service, sufficiently into consideration. They take resources like network connectivity for granted and do not provide an integrated networking approach considering Quality of Service (QoS) or other real-time aspects of the message exchange between possibly thousands of components. This paper presents the concept of a fully managed network virtualization framework to provide the required connectivity between components within a virtualized service platform respecting all service requirements, e.g. as expressed by interactive real-time services, on transport layer.
