Abstract:The concepts of cloud computing and Internet applications have expanded gradually and have become more and more important. Researchers need a new, highspeed network to build experimental environments for testing new network protocols without affecting existing traffic. In this paper, we describe a way to integrate NetFPGA platform, OpenFlow concept and NetFPGA reference designs into a network testbed to improve the packet processing speed and the dynamic adjustability for network emulation experiments. Furthermore, combined with Tunneling and VPLS, the proposed network testbed can be connected to distributed network, thus providing researchers a traffic-controllable and NIC-programmable experimental networking testbed in intra-communicating part.
