Which option is a consortium of service providers and vendors that addresses NFV architectures and orchestration for NFV.
Click on the arrows to vote for the correct answer
A. B. C. D.C.
The correct answer to the question is C. ETSI (European Telecommunications Standards Institute).
ETSI is a consortium of service providers and vendors that focuses on standardizing telecommunications technologies. In particular, ETSI has taken a leading role in developing standards for Network Functions Virtualization (NFV) architecture and orchestration.
NFV is a technology that enables the virtualization of network functions, such as routing, switching, and firewalling, by running them on virtual machines or containers instead of dedicated hardware. NFV promises to increase the agility and flexibility of network services, reduce costs, and improve scalability.
To achieve these goals, NFV requires a standardized architecture and orchestration framework that enables the deployment, management, and scaling of virtualized network functions. ETSI has developed such a framework, called the NFV Reference Architecture, which defines the main components, interfaces, and protocols needed to build an NFV infrastructure.
In addition to the NFV Reference Architecture, ETSI has also developed a set of NFV specifications and requirements, such as the NFV Management and Orchestration (MANO) framework, the Virtualized Infrastructure Manager (VIM) interface, and the NFV Infrastructure (NFVI) specifications. These documents provide guidelines and best practices for implementing NFV solutions and interoperating with other NFV components.
Therefore, ETSI is the correct answer to the question since it is the consortium that has taken the lead in developing NFV standards and frameworks, and is recognized as the main standardization body for NFV in the telecommunications industry.
