摘　　要：介绍了构建网络创新试验环境方面的一些实践。认为在中国试验网方面,主要采用稳定性与先进性相结合的技术路线:在主干网,基于虚拟可扩展局域网(VxLAN)灵活构建虚拟网络,为用户提供网络资源;在边缘的试验站点,提供虚机和可编程设备等丰富的试验资源。在国际试验网方面,则主要采用域间分布式协作与域内集中式管控相结合的技术路线,基于所提出的WE-Bridge域间软件定义网络(SDN)机制为用户提供跨域试验网和可编程资源。In this paper, the practice on experimental environment for network innovation is introduced. For the internal testbed, the technical route which combines the stability with advancement is adopted: virtual networks based on virtual extensible local area network (VxLAN) in the backbone can be flexibly constructed,which can provide network resources to the users; rich test resources including virtual machines and programmable devices can be provided on the edge of this testbed. For the international testbed, the technical route which combines the interdomain distributed cooperation with centralized management and control is adopted,and cross-domain experimental networks and programmable resources can be provided through the soft defined network (SDN) WE-Bridge mechanism.
