In computer science, network function virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.
NFV relies upon, but differs from, traditional server-virtualization techniques, such as those used in enterprise IT. A virtualized network function, or VNF, may consist of one or more virtual machines running different software and processes, on top of standard high-volume servers, switches and storage, or even cloud computing infrastructure, instead of having custom hardware appliances for each network function.
For example, a virtual session border controller could be deployed to protect a network without the typical cost and complexity of obtaining and installing physical units. Other examples of NFV include virtualized load balancers, firewalls, intrusion detection devices and WAN accelerators.

In this 101 level tutorial, we introduce NFV. Learn more here: http://www.ciena.com/connect/blog/What-is-NFV.html Definition: Network Function Virtualization, or NFV, is way to reduce cost and accelerate service deployment for network operators by decoupling functions like a firewall or encryption from dedicated hardware and moving them to virtual servers. Instead of installing expensive proprietary hardware, service providers can purchase inexpensive switches, storage and servers to run virtual machines that perform network functions. This collapses multiple functions into a single physical server, reducing costs and minimizing truck rolls. If a customer wants to add a new network function, the service provider can simply spin up a new virtual machine to perform that function.
Analysts predict NFV hardware and software to be a $10+B market by 2018, yet few organizations have experience deploying NFV infrastructure at a large scale. In this talk, we will discuss lessons learned and the development that resulted as part of a specific large-scale NFV infrastructure roll-out that started in 2015. We will discuss the OpenStack pod design for NFV that emerged after multiple iterations between Red Hat, Big Switch and Dell. This solution is currently being deployed in n

Network Function Virtualization makes it possible for each node in the network topology to become a micro-datacenter, able to host various applications. In this way, latency-sensitive applications such as those installed in autonomous cars, don’t have to be hosted in a distant datacenter. Instead, they can be as close to the user as possible. As a result, the communication path between the user and the application becomes shorter and the application server latency can be reduced to 1 millisecond. Comarch OSS is a modern solution that helps your network to compare network queries intelligently and automatically prioritizes them based on their importance. Thus the decisions about where the application should be hosted and how many virtual machines it needs to run smoothly are also automate...

My middlename was 'never go to bed'
no curtains in the world would draw my weary head
for hours and hours and hours my eyes
were hungry in the night
eating the hours and eating the years - my tinted appetite
Is it bedtime now?
it's too late
Today, I crawl into bed
today, like the grown ups I met
for hours and hours and hours I sleep
a Radioheaded creep
with sheets and with pillows I fly into this grown up lie
Is it bedtime now?
it's too late
For me it's a shame
