Ciena 101 level tutorial video gives good insight on Network Function Virtualization (NFV).
Although Network Function Virtualization (NFV) has been around since it was first identified by ETSI group in 2012, it is still one of the hot topics in networking today.
We wrote plenty of articles regarding Network Function Virtualization (NFV), from its general definition and usage to whitepapers which talk about implementing NFV. Currently, there is a big MPLS + SDN + NFV World Congress 2018 event going on in Paris, France, with plenty of sessions about future NFV implementations.
In case you missed it, Network function virtualization (NFV) is network architecture concept set by the ETSI’s Industry Specification Group for Network Functions Virtualization (ISG NFV) to provide a new way to design, deploy and manage specific networking services. It is used for several virtualization network functions, including firewalls, network address translation (NAT), domain name service (DNS), caching, intrusion detection and other specialized network applications.
The video which you can see above is an addition to the extensive post written on Ciena.com, which digs a bit deeper into Network Function Virtualization, its advantages, and its benefits as an open standard.
The video is definitely a good intro into the world of NFV and gives insight on how NFV can be used for certain network functions that were previously deployed by using proprietary hardware, which is both costly and difficult to upgrade.
