AUSTIN, Texas -- Big Communications Event -- The NIA's Steve Vogelsang wants to make sure that the communications industry does not lose heart with NFV as the industry struggles with turning virtualization into a reality.
Speaking here earlier this week, Vogelsang, CTO of IP & Optical Networks at Nokia Corp. (NYSE: NOK) and chair of The New IP Agency , argued that the series of live NFV interoperability demonstrations that took place on the BCE exhibit floor shows that the virtualization technology can and does work. The NIA commissioned the European Advanced Networking Test Center AG (EANTC) to conduct the six independent, multivendor demonstrations, comprising NFV infrastructure (NFVi) elements, virtual network functions (VNFs), orchestration systems and test and measurement technology.

"This is fantastic stuff," he said. "The challenge, of course, is how do you get there?"
Despite the "disillusionment and complexity we're now seeing with NFV" in some quarters, Vogelsang said "a number of things still matter" with the technology. Listing those items, he ticked off hardware performance, scalability, resiliency, manageability and evolving IP fabric. He also cited abstraction and end-to-end network optimization, noting that they and the evolving IP fabric rely more on SDN technology than NFV.
"There's a lot of complex stuff going on there," he noted. "And we're trying to do it all at once."
Vogelsang stressed that the independent multivendor testing regime is saving "the entire communications industry from having to redo these tests" each time. Once the testing is well underway, he said plans call for expanding the scope of NIA to other areas, without elaborating on them.
