I am in Barcelona this week for Mobile World Congress, but it somehow feels as if the mobile industry is trying to turn itself virtual. The topic of Network Function Virtualization seems to pop out at me everywhere I look around the event. I have already talked in past blogs about how Procera sees virtualization as a great enabler for innovation, but the activity this week in the NFV space signals a shift from “talking” about virtualization to “doing” virtualization. There are still some hurdles to be overcome for sure, but the conversations that are taking place now are moving beyond the “Let’s do a proof of concept” to “Let’s deploy this in 2014”.
