Logically isolated group network for virtual convergence environment over SD-WAN

Software-defined wide-area network (SD-WAN) is gaining strong momentum as distributed cloud evolves. The new cloud infrastructure requires novel and innovative network technologies based on virtualization, automated resource (e.g., datacenters, VMs, networks) convergence, ultra-high data-forwarding performance, and strict network security. To meet the demands, this paper suggests a scheme for logically isolated group network for virtual convergence environment and evaluates its performance in terms of virtual network generation performance over the de facto SD-WAN infrastructure deployed on the advanced research network (KREONET), which operates in six distant cities in Korea and the USA.
