1 Scope
The present document describes a set of informative interoperability test guidelines for NFV capabilities that require
interactions between the components implementing NFV functionality, namely, the NFVO, VNFM, EM-VNF and
VIM-NFVI (Functions under Test).
The guidelines in the present document follow the interoperability testing methodology described in ETSI
GS NFV-TST 002 [i.1] and are implementation agnostic. The capabilities in scope are enabled by the interfaces on the
main NFV reference points between the Functions Under Test:
• Or-Vi;
• Or-Vnfm;
• Vi-Vnfm; and
• Ve-Vnfm.
