Abstract
We have been conducting research on network virtualization infrastructure and its applications. We have built infrastructure to slice network and computational resources and provide network designers with systematic interfaces to reserve a slice of resources and construct arbitrary networks on top of it. In doing so, we have developed three different types of testbeds: CoreLab, VNode and WiVi. CoreLab is a software-based testbed constructed on top of commercial, off-the-shelf x86 hardware, while VNode involves designing new hardware based on production routers. WiVi is a recently developed WiFi virtualized testbed that can be connected to CoreLab to enable wired wireless converged network slices. In this talk, we introduce our definition of network virtualization and its applications in the context of network testbeds as well as network architectures. We especially elaborate the detailed design and implementation of our network virtualized testbeds, CoreLab, VNode, and WiVi.
