ETSI expects its newly shared NFV Release 2 specifications will further advance the telecommunications industry's adoption of network functions virtualization.
"This represents another major step towards our objective of defining a comprehensive set of specifications that will facilitate the deployment of NFV throughout the telecommunication industry, with significant benefits being subsequently derived in many interrelated sectors," says Diego Lopez, senior technology specialist at Telefónica and newly appointed chairman of the ETSI Industry Specification Group on NFV (ETSI ISG NFV), in a statement. "The combination of wide consensus and experimental evidence has led to NFV being recognized as a completely viable and highly valuable technology. This has allowed us to make progress at a fast pace."
The update, founded on ETSI ISG NFV documentation from 2014, includes 11 additional group specifications that address requirements, interface descriptions and information models that enable interoperability based on the ETSI NFV Architectural Framework, according to the organization. Release 2, unveiled on Tuesday, describes required functional needs vis-à-vis functional areas like managing virtualized resources, virtualized resource capacity management, lifecycle management of network services and virtualized network functions, and network service fault and performance management, ETSI says.
A Foundation for a Framework
Diego Lopez, senior technology specialist at Telefonica and newly appointed chairman of the ETSI Industry Specification Group on NFV, says the ETSI NFV Architectural Framework will be the foundation upon which future virtualization of the network is established.
The combination of a well-defined standards structure and the open source community's support accelerates the development process and improves interoperability, Lopez says.
"I am therefore confident that the ETSI NFV Architectural Framework will be the foundation upon which future virtualization of the network is established -- enabling cost-effective allocation of resources and the rapid addition of new services, while still ensuring the highest degrees of security and reliability, as well as painless and seamless integration with existing infrastructure," he adds.

Release 2 is an industry milestone, Carsten Rossenhövel, managing director at European Advanced Networking Test Center AG (EANTC)
, says via email. EANTC is a member of ETSI.
"Important functional requirements, reference points and interfaces have been agreed. EANTC has contributed to TST002, providing an initial industry standard for NFV interoperability testing. EANTC will take the ETSI Release 2 specifications into account for our multi-vendor NFV interoperability tests on behalf of the New IP Agency and in collaboration with ETSI's first NFV PlugTest," he says. "The new ETSI specifications will enable us to accelerate NFV interoperability testing. Service providers will benefit from better understanding of interfaces required for multi-vendor NFV implementations, enabling stronger and more precise RFPs for NFV components."
Jeff Hannah, NIA director, agreed that Release 2 is an important step for virtualization interoperability.
"The NIA applauds the ETSI ISG on NFV for NFV Release 2, a much needed step forward towards defining interoperability amongst NFV elements within a cohesive and industry-agreed architectural framework. Throughout the development of evaluations hosted by the NIA to date on lifecycle management, service-function chaining and VNF management, the NIA has leveraged the requirements, models and protocols outlined by the ISG on NFV when and where they have been specified," he says. "NFV Release 2 will provide the NIA and its membership with additional, and much needed, clarity on the specifications, requirements, and models necessary to address additional and more comprehensive multi-vendor interoperability evaluations that support service providers' adoption of virtualized networking solutions."
