As part of the most recent mobile broadband standards, 5G and 6G, network slicing solutions will shape the future of networks. By employing network slicing, network operators can protect participants against different attacks over the network by isolating devices and providing resource guarantees. Currently, to evaluate new network-slicing solutions, network researchers or engineers have to either evaluate the solution in a virtual environment that can not accurately scale to the performance of hardware platforms or invest significant portions of time in network configuration on hardware platforms. To quickly prototype network slicing solutions and other solutions depending on software-defined networking (SDN) features, we introduce a hardware abstraction layer featuring a vendor-independent API to manage hardware platforms and a new testbed solution featuring topologies similar to common network evaluation platforms like mininet.In this demo, we showcase a network-slicing solution leveraging SDN. The audience can visually observe the performance of the communication channel before and after denial-of-service attacks and with and without the secure network slicing.
