动态服务功能链(SFC)技术研究进展

摘要

The dynamic Service Function Chaining(SFC)technology drives the construction of a highly scalable carrier network service flow processing platform of the operator network, providing a new solution for the network reconstruction and architecture evolution. Firstly, the paper starts with the background of dynamic SFC development, combining the dynamic SFC architecture, including the orchestration plane, control plane and data plane. Secondly, the key technologies of dynamic SFC are expounded, and then the application of dynamic SFC technology in typical scene is discussed. Finally, the future research work of dynamic SFC technology is prospected.%动态服务功能链(Service Function Chaining,SFC)技术驱动了高度可拓展运营商网络业务流处理平台的构建,为网络重构和架构演进提供了一种新的解决方案.介绍了动态SFC发展背景,梳理了动态SFC体系结构,其中包括编排平面、控制平面和数据平面;深入阐述了动态SFC的关键技术,然后论述了动态SFC技术在典型场景下的应用研究;最后,展望了动态SFC技术未来研究工作.
