As the network functions virtualization (NFV) revolution comes to service provider and cloud communities, there are some concerns about this new technology. One of the major questions is how to design enough performance in NFV to keep pace in high-subscriber, mission-critical environments.
Can NFV live up to the performance expectations of the most demanding networks, including global service providers? There is evidence that there is more work to do to transform this IT technology – but some key technology tools are emerging to put enough performance in NFV to perform for the most demanding applications, including communications.
The advantage of NFV is that it can deliver network functionality via software running on industry-standard, commercial off-the-shelf (COTS) hardware. Any number of software services can be deployed on this generic hardware, which can assure interoperability and flexibility.
