¿µ¹®³»¿ë¿ä¾à Service Function Chaining (SFC) consists of SFC data plane and control plane from the aspect of architecture. The standard describes the requirements for delivering information between SFC control elements and SFC functional elements. By capturing the information conveyed via a set of control interfaces, the standard defines Yang data model of the management operations performed in a SFC control plane.
