Network Function Virtualization

Definition

Network Function Virtualization (NFV) is a technology that uses virtualization to manage network services. Instead of relying on dedicated hardware appliances, NFV allows these services to run as software instances on standard servers. This shift leads to improved flexibility, reduced costs, and faster deployment of network services, which is particularly relevant in the fast-paced environment of emerging technologies and their impact on incubation.

5 Must Know Facts For Your Next Test

1. NFV separates network functions from dedicated hardware appliances, enabling these functions to run on standard server hardware for cost efficiency.
2. The adoption of NFV can accelerate innovation in service delivery by allowing faster deployment and scaling of network services without the need for new hardware.
3. NFV is closely linked to cloud computing and software-defined networking (SDN), which together contribute to more agile and responsive network management.
4. By utilizing NFV, businesses can improve their operational efficiency through reduced maintenance costs and enhanced resource allocation.
5. NFV fosters a competitive environment by enabling smaller startups to offer innovative networking solutions without the high upfront costs associated with traditional hardware.

Review Questions
