Novel Applications and Experiments on Programmable Infrastructures

We show novel applications as use cases and experiments on programmable infrastructures. We have designed and implemented a programmable infrastructure called VNode on a Japanese testbed network. The VNode infrastructure allows the network developer or researcher to create a slice. A slice is a set of connected virtualized computational resources and link resources. The user can easily configure and modify own network topology and deploy service functions as software like SDN and NFV. We realize multicast streaming and adaptive bit rate streaming by deploying video processing functions in a slice. Moreover, we realize automatic function deployment that responds to traffic intensity. We conduct some experiments to confirm the feasibility and usability of our use cases and the VNode infrastructure. We establish data streaming via a slice with enhanced functionalities and measure the resource utilization rate. Furthermore, we conduct some experiments on a federated slice established between VNode and GENI, which is a programmable infrastructure in the U.S. The results show that we can enhance service functionalities and use resources more efficiently by deploying software functions on programmable infrastructures.
