Hello, everyone.


As we know, the current physical network architecture has been gradually replaced by NVF, but I'm still curious to see what the main advantages of NFV are?

Can someone explain this issue?

Hello, dear.

The Advantages of NFV are as follows:

NFV applies to various network solutions, including SD-WAN, network slicing, and mobile edge computing. NFV decouples software functions from hardware and brings a number of benefits with the improvement of this standardized architecture:

Flexible services

NFV offers the flexibility of running VNFs across different servers or moving them around as needed when demand changes. This accelerates the delivery of network functions and applications. For example, when a new network function needs testing, you can simply spin up a new VM to perform that function. Just as easily, the VM can be decommissioned when the function is no longer needed. This offers a convenient method for testing new functions.

Less spending

With NFV, multiple virtualized network functions can run on a single hardware server. This means that less physical hardware is needed, which allows for resource consolidation to reduce costs in spaces and power needed for hardware. However, the investment is large in the initial phase of migration from traditional physical devices to NFV, and the return on investment (ROI) in the short term is not significantly higher than that of using traditional physical devices.

Higher resource utilization efficiency

NFV eliminates the need for hardware changes when network requirements change. The basic network architecture can be quickly updated using software, avoiding physical device redundancy and migration.

No vendor lock-in

By running VNFs on general-purpose hardware, NFV decouples network functions from dedicated hardware and eliminates vendor-lock due to specific functions, reducing network device maintenance costs.

Hope this can help you!
