https://www.ciscolive.com/c/dam/r/ciscolive/us/docs/2016/pdf/LTRSPM-2022.pdfNFV stands for Network Functions Virtualization. It is a network architecture approach that decouples network functions from proprietary hardware appliances and runs them in software. The main goal of NFV is to improve the flexibility, scalability, and cost-effectiveness of network infrastructure by replacing traditional hardware-based network devices with software-based virtual machines.
The characteristics of NFV architecture approach are:
A. It decouples the network functions from proprietary hardware appliances: This is one of the fundamental characteristics of NFV. It involves moving network functions such as firewalls, routers, load balancers, and intrusion detection systems from dedicated hardware devices to software running on commodity servers or cloud infrastructure. By doing so, NFV enables network operators to deploy and scale network services more quickly and cost-effectively.
B. It provides 70% more efficiency of network infrastructure: This statement is not entirely accurate. While NFV can improve network efficiency and reduce costs, the exact percentage of improvement will depend on various factors such as the type of network functions deployed, the hardware resources available, and the workload patterns. Therefore, this statement is not a characteristic of NFV.
C. It is specially designed for Internet providers: NFV is not designed exclusively for internet providers. It is a general-purpose network architecture that can be used by any organization that needs to deploy network services quickly and efficiently.
D. It is specially designed for telecommunications service providers: While NFV was initially developed by telecommunications service providers, it is not exclusively designed for them. Any organization that needs to deploy network services can benefit from NFV.
E. It typically includes a hypervisor: This is another characteristic of NFV. Since NFV involves running network functions as software, it typically requires a hypervisor or a virtual machine manager to abstract the underlying hardware and provide a virtualized environment for the network functions to run on. The hypervisor allows multiple virtual machines to share the same physical hardware resources while providing isolation and security between them.
