NetFPGA-based scheduler implementation for resource virtualization of Future Internet testbed

Recently, research activities on the Future Internet are being actively performed in many countries. In Korea, ETRI and four universities focus on implementation of a research testbed on the Future Internet named as `FiRST(Future Internet Research for Sustainable Testbed)´. In the `FiRST´ project, four universities are performing a sub-project in collaboration named as `FiRST@PC´ that is for a testbed implementation using programmable NetFPGA platform-based OpenFlow switches. Currently, the research on the virtualization of the testbed is being performed that has a purpose of supporting an isolated network resource to individual researcher. In this paper, we have implemented a traffic scheduler for providing QoS to virtualized network slices by using the programmable platform that performs a hardware-based packet processing, and implemented a testbed using that traffic scheduler. We performed a performance evaluation of the traffic scheduler on the testbed. As a result, we show that the hardware-based NetFPGA scheduler can provide reliable and stable QoS to virtualized networks of the Future Internet Testbed.
