6.1.2 Standardization activities at ETSI ISG NFV

ETSI ISG NFV has been active since 2012, with its NFV vision that “An open ecosystem for NFV enables rapid
service innovation for network operators and service providers” and that “Innovation in end-to-end services
is enabled by software-based deployment and operationalization of virtualized network function (and
network services) on independently deployed and operated NFV infrastructure platforms”. In the 2013-2014
time frame, it conducted extensive pre-standardization study and published the Release 1 specifications,
regarding the NFV framework architecture, use cases, terminology and so forth. In 2016, it published Release
2 specifications and reports, including functional requirements, interface and information model of reference
points for the management and orchestration function block, called NFV-MANO. In addition, the stage 3
specifications for the reference points owned by ETSI ISG NFV has been defined and will be included in
Release 2.

NFV is a technology enabler which is relevant to a large number of use cases including what were identified
for IMT-2020, and consequently, to different stakeholders and organizations: consuming upstream
technologies and enabling an ecosystem for other technologies to make use of it. ETSI ISG NFV has been
leading harmonization of information models applicable to NFV, focusing on SDN and other related
technologies. The alignment has been studied for the information models defined by parties such as 3GPP,
ATIS, BBF, DMTF, ETSI NFV, IETF, ITU-T, MMF, OASIS/TOSCA, OCC, ODL, ONF, OPNFV, TM Forum.
