Abstract Abstract
This document mainly introduces the practice of NFV decoupling test. This document mainly introduces the practice of NFV decoupling test.
Based on the product development situation of the current vendors, Based on the product development situation of the current vendors,
the decoupling test is carried out between NFVI&VIM, VNFM&VNF and the decoupling test is carried out between NFVI&VIM, VNFM&VNF and
NFVO. Through a series of tests to explore some of the problems NFVO. Through a series of tests to explore some of the problems
encountered in the current stage of NFV decoupling testing, provide encountered in the current stage of NFV decoupling testing, provide
ideas for the subsequent development of NFV products. ideas for the subsequent development of NFV products.
