Re: Virtualization: Network Design & Infrastructure
SDN is a bit like being able to reroute the trains from a central, programmable standpoint, rather than the old phyiscal switches.  NFV is basically like taking your home wireless router or what have you, but it runs as software on a computer. The analogies not great, because there are fewer reasons for a home consumer to need NFV, but at the customer premise at a large enterprise, having a number of network functions run as software in the provider's data center rather than a number of physical appliances at the customer prem is pretty sweet -- it means less hardware to upgrade, easier troubleshooting and other benefits. Virtualization of the whole network has cost and elasticity benefits.  Imagine turning off routers or other hardware as the requirements for your network reduce in the evening or on the weekend.  Etc.
