¿µ¹®³»¿ë¿ä¾à This standard specifies interfaces over the Reference Points named Ve-Vnfm-em and Ve-Vnfm-vnf in the NFV framework. For this, section 6 defines the basic concepts of VNF and functional interactions between VNF and EM, and VNF and VNFM. Section 7 defines requirements of the Reference Points and their interfaces. Section 8, 9 and 10 specifies operations supported in the interfaces for each Reference Point. Annex I illustrates information flow of instantiation/termination of a VNF instance in both a direct and indirect mode,
Change notification, scaling, performance/fault management of virtualized resources for a VNF instance as examples. Finally, Annex II shows RESTful APIs for the VNF lifecycle management interfaces.
