Reconfigurable Network Simulation Testbed Based on Network Virtualization

Network Virtualization is currently considered as one of the most important approaches to the development of future Internet architecture. In addition to paperwork, most related works also need to be evaluated and verified through testbed. Some large- scale research network test platforms are designed. But they are not suitable for researchers to carry out small-scale network virtualization experiments, because they are quite complexity or still at primary stages. Taking use of Click Modular Router, this paper proposes a future Internet testbed architecture based on network virtualization, supporting the reconfiguration of IPv4 and IPv6 protocols. Experimental results of multi-protocols and multicast applications show that the future Internet testbed proposed in the paper is efficient for future Internet experiments.
