NFVI evolution, focusing on enhancements to support lightweight virtualization technologies such as OS containers, optimizing NFV Infrastructure (NFVI) abstraction for reducing the coupling of VNFs to infrastructure, and optimizing networking integration into the infrastructure fabric to ease the connectivity for Virtualized Network Functions (VNFs) and Network Services (NSes).While the specific work items are under progress, key areas of focus for the future NFV Release 4 have been identified, which include: NFV Release 4 specification work has been formally launched in summer 2019. Progress in the industry is continuously monitored, including feedback from implementations, open source communities, and other standards bodies, and the identification of gaps to be addressed.Ībbreviations of the NFV working groups mentioned in this page: The ISG NFV dedicates a continuous support for proper referencing of NFV specifications by industry stakeholders, including not only service providers or network equipment vendors, but also other implementers such as open source communities. Going forward, the ISG NFV continues to develop new specifications that meet the needs of the industry, with maintenance cycles for its already published specifications. Release 2 development of architecture, interfaces and information model aspects (aka stage 2 specifications) ended in Q3 2016 when work on Release 3 started, in parallel to the specification of the implementable protocol and data model solutions (aka stage 3) of interfaces, descriptors and other artifacts. The specification of new features and capabilities in planned releases had as outcome subsequent tranches referenced as "Release 2", "Release 3", etc. The ISG NFV community has continued its work by developing normative specifications, as well as informative studies. Our Role & Activities OverviewĮTSI ISG NFV undertakes work in 2-year phases.ĭocuments published during the first phase (2013-2014) were considered as pre-standard studies and are sometimes referred to as “Release 1”.
While the former provides the means to dynamically control the network and the provisioning of networks as a service, the latter offers the capability to manage and orchestrate the virtualization of resources for the provisioning of network functions and their composition into higher-layer network services. SDN and NFV are complementary but increasingly co-dependent. Key enabling technologies for this vision include SDN (Software Defined Networking) and NFV (Network Functions Virtualisation). In the same way that applications are supported by dynamically configurable and fully automated cloud environments, virtualized network functions allow networks to be agile and capable to respond automatically to the needs of the traffic and services running over it. A hard-wired network with single functions boxes is tedious to maintain, slow to evolve, and prevent service providers from offering dynamic services. In a digital world, the innovation cycles accelerate and require greater flexibility and dynamism than hardware-based appliances allow. The launch of new services often demands network reconfiguration and on-site installation of new equipment which in turn requires additional floor space, power, and trained maintenance staff. Modern telecoms networks contain an ever-increasing variety of proprietary hardware.
If you would like to participate in this work, please contact the NFV support team. ISG NFV, like any other ETSI Industry Specification Group is open to ETSI members and non-members alike, with different conditions depending on ETSI membership status. This large community is still working intensely to develop the required standards for NFV transformation incorporating latest technologies, as well as sharing their experiences of NFV implementation and testing in multi-vendor environments.
#Standard network kit series
The early Proof of Concepts (PoCs) efforts have evolved and led to a series of interoperability events ( NFV Plugtests). Founded in November 2012 by seven of the world's leading telecoms network operators, ETSI ISG NFV became the home of Network Functions Virtualisation (NFV).Īlmost seven years and over 100 publications later, the ISG NFV community has evolved through several phases, its publications have moved from pre-standardization studies to detailed specifications (see Release 2 and Release 3).
