Overview
NFV aims to transform the way network operators architect networks by evolving standard IT virtualization technology to consolidate many network equipment types onto industry-standard high-volume servers, switches, and storage.
Key Components
- Virtual Network Functions (VNFs): Software implementations of network functions (e.g., firewalls, load balancers, routers) that were previously hardware-based.
- NFV Infrastructure (NFVI): The hardware and software components (compute, storage, networking) that provide the environment in which VNFs run.
- MANO (Management and Orchestration): The framework for managing the lifecycle of VNFs and the infrastructure.
Benefits
- Reduced CapEx: Less need for expensive, proprietary hardware.
- Reduced OpEx: Lower power consumption and simplified management.
- Scalability: Easily spin up or down network services based on demand.
