Within the telco market at the moment, there is an increasing emphasis on developing Network Functions Virtualization for various parts of the network. Yet what is the optimal management model to govern new virtualized network elements?
Dr Yuri Gittik at RAD Data believes that ‘Distributed NFV’ is the way forward:
“The notion of NFV architecture being just a centripetal force that relocates functionality from a customer site to the network is not the complete picture. Ideally, virtualized functions should be located where they will be both most effective and least expensive, which means NFV should have the option to return to the customer site. These two virtualization trends should be complementary and not be the networking equivalent of two ships passing in the night.”
Yet as Tom Nolle from CIMI Corporation points out, “The traditional picture of NFV is that it would replace existing network appliances/devices with hosted functions. Most presume that this hosting will be done on general-purpose servers, and in fact that’s what the White Paper that launched NFV actually says. Most also believe that the hosting will take place in operator data centers, and most likely will. But RAD’s announcement demonstrates that there’s more to it.
“It’s going to be hard to contain NFV. Some of its impacts are going to spread out to involve things that the original mandate never included, simply because the original mandate of commercial servers won’t optimally support the full range of network service models. I don’t think that would surprise the founders of NFV, but it might surprise the vendors who are looking to build NFV support. In particular, it might surprise those who are looking at the area of ‘NFV management’.”
So perhaps there will never actually be a single management system for NFV. But what is clear is that the management evolution of NFV is crucial to NFV’s future success – management solutions need to be thought through very carefully by all parties.
NFV will be discussed in detail at the forthcoming Carrier Network Virtualization conference in Palo Alto on 9-11 December 2013, a show specifically focusing on the relevance of SDN and NFV to the worldwide carrier community.

NFV and SDN are going to force the dissonance between “networks are pipes” and “networks are supercomputers” to the industry’s surface.
