Network service providers have many options when modernizing service delivery: cloud interconnects, SD-WAN, SDN, vCPE, NFV, etc. Geography often plays a deciding role. ETI Software’s VP of Engineering, David Tidd, discusses NFV and how ETI is working with providers to implement it.
Network Function Virtualization (NFV) is an architectural concept of virtualizing proprietary network nodes in simplest form. When chaining virtualized network nodes together, NFV, becomes a building block on which communication services are built.
First one must avoid vendor lock-in. Implementing a strategy to “white box” hardware (also called commodity servers) will have an immediate effect on initial expense. Using software to emulate the network node function upon generic equipment adds programmability into each solution.
To accomplish this there are three main layers:
Virtualizing in this manner saves both CapEx and OpEx: CapEx from the initial expense, OpEx by simply being repurposed with new intent or quickly reimagined.
NFV’s primary purpose is to replace highly reliable network appliances. To successfully accomplish this mission it requires:
A comprehensive strategy for network function virtualization can have a profound effect on profitability. It comes with challenges: many operators aren’t prepared to deploy NFV at scale. Partner with ETI and begin to successfully realize NFV for your organization.
