Research of Network Innovation Experimental Environment Based on Network Virtualization

In order to solve the problems related to future network innovation,researchers propose numerous solutions.However,these solutions need to be tested in an large-scale network experimental environment,which cannot be totally supported by the current Internet.Thus,constructing a network innovation experimental environment is meaningful for the further develop of the Internet.We propose Tsinghua University Network Innovation Environment(TUNIE),a network innovation experimental environment in China,aiming to support research in future network based on network virtualization.In this paper,we survey the past and the state-of-the-art of network innovation experimental environment,as well as certain key topics.Then we introduce design goals and key technologies of TUNIE.TUNIE is already deployed in several clusters,applied in teaching and research,and supports some network innovation experiments.
