name: VNF
full_form: Virtual Network Function
context: uploads a valid VNF package into a NFVO. The NFVO verifies the integrity of the VNF package by validating the digital signature of the VNF package using the certificate of VNF vendor according to the documentation; 3. During VNF package on boarding, the tester uploads a not-valid VNF package into a NFVO. The NFVO validates the digital signature of the VNF package using the certificate of VNF vendor; 4. During VNF instantiation, the VIM selects a VNF image with a correct integrity protection value from the image repository to instantiate the VNF image. 5. During VNF instantiation, the VIM selects a VNF image with an incorrect integrity protection value from the image repository to instantiate the VNF image. Expected Results: 1. The VNF package is successfully on boarded into the NFVO; 2. The not-valid VNF package is not on boarded; 3. The VNF image with a correct integrity protection value is instantiated by the VIM; 4. The VNF image with an incorrect integrity protection value is not
description: A Virtual Network Function (VNF) is a software implementation of a network function that can be deployed on a virtualized infrastructure, providing specific network capabilities and services. In the context of NFV (Network Functions Virtualization), VNFs are critical components that enable the creation of virtual networks and provide various network functions such as routing, switching, and security.
explanation: The text explicitly defines a VNF as a software-based network function deployed on a virtualized platform, emphasizing its role in providing network capabilities within an NFV environment.
