SDN/NFV关键技术问题分析和标准化进展

[摘要] 着重分析SDN/NFV技术在商用部署中面临的关键技术问题，包括开放接口标准化和互操作,通用硬件和控制器的性能，与现网系统的协同、安全以及集成部署等问题，并梳理国际标准组织和开源项目在SDN/NFV技术领域的进展情况。认为SDN/NFV的部署应是一个渐进式的过程，传统网络与SDN/NFV网络将会长期共存。业界需要尽快统一架构、接口和协议标准，推动不同厂商功能组件的系统集成，从而最终实现网络即服务。

[Abstract] In this paper, the current hot issues of soft defined network(SDN)/network function virtualization (NFV) industrial development are analyzed, including standardization and interoperability of open interface, performance of general-purpose hardware and SDN controller, cooperation with existing operation system, security and integration deployment. And the progress status of standardizations and open source projects in the SDN/NFV field are also concluded. It is believed that the deployment of SDN/NFV should be a gradual process, and the traditional network and SDN/NFV network will coexist for a long time. The architecture, interface and protocol standards should be unified as soon as possible, so as to promote the integration of different functional components of different manufacturers. In this way, network as a service (NaaS) can be realized.
