Virtual Network Function (VNF)

A Virtual Network Function (VNF) is a software-based version of a traditional network component, like a firewall or router, that runs on standard hardware instead of specialized equipment. It enables flexible, scalable, and cost-effective management of network services by deploying and managing these functions as software instances on virtualized infrastructure. VNFs are essential building blocks in modern networks, especially in 5G and cloud environments, allowing service providers to quickly adapt to changing demands and improve service delivery without the need for physical hardware changes.
