Network Functions Virtualization (NFV) and Software Defined Networks (SDN) enable rapid networks and services innovation for all participants in the ecosystem. Decoupling network functions from the underlying physical infrastructure using virtualization technologies enables Service innovation.
SDN allows programmability of the NFV infrastructure to support the deployment of new network functions in a variety of environments including campus & enterprise networks, data centers, telecommunications networks providers, ISPs, cloud providers and over-the-top (OTT) applications & services providers.
NFV enables network capacity and functionality to be decoupled, allowing network functions to be dynamically deployed whenever they are required and wherever they can be hosted.
(SDN/NFV provides a massive steroid boost to the Network (Wireless / Wireline))
With 4G, 5G, IIOT, Industry4.0, etc.. we will see the faster deployment of NFV/SDN.
Feel free to send questions relating to the dimensioning of Networks for NFV / SDN / MANO.
Compared to the PNF approach, NFV allows Functions to be packaged as a Virtual Machine (VM) or as a “Container”, e.g. LXC / Docker. Each vendor will have a questionaire that will be used as an input to estimate the number of Virtual Resources (Memory, CPU, Networking, Storage, etc..) that will be required. MANO will be used to help to setup and deploy the required VMs on a Data Center(s).
