构建网络创新试验环境的探索

[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。

[Abstract] 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 inter-domain 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.
