The practice of NFV decoupling test
draft-long-nfvrg-nfv-decoupling-test-02
Abstract
This document mainly introduces the practice of NFV decoupling test.
Based on the product development situation of the current vendors,
the decoupling test is carried out between NFVI&VIM, VNFM&VNF and
NFVO. Through a series of tests to explore some of the problems
encountered in the current stage of NFV decoupling testing, provide
ideas for the subsequent development of NFV products.

1. Introduction
3GPP has adopted the R15 standard and the SBA (Service Based
Architecture) architecture, which further splits multiple NFs(Network
Functions) in the 5G core network into multiple NFS (Network Function
Service), each NFS has the characteristics of independent autonomy.
But the existence of multiple NFSs in the clouded NFV also brings
compatibility problems. Therefore, one of the key requirements of
the 5G core network for the clouded NFV platform is open. The cloud
platform needs to implement decoupling deployment and network
resource sharing, thus not only avoiding the lock-up of single-
vendors but also can build an open ecosystem based on open source
projects.
But, there are still many problems in the decoupling of the NFV
platform. The interfaces of different vendors are not standardized
and are not unified, which makes it difficult for the components of
the NFV platform to properly connect and provide complete services.
According to the [ETSI_GS_NFV_002], it divides the NFV into multiple
modules as shown in Figure 1.
o Virtualized Network Function (VNF).
o Element Management (EM).
o NFV Infrastructure, including: Hardware and virtualized resources,
and Virtualization Layer.
o Virtualized Infrastructure Manager(s) (VIM).
o NFV Orchestrator.
o VNF Manager(s).
