Hi
Thanks for good discussion.
It is not fair to pinpoint on one or two issues while looking at NFV adoption. Instead it needs a comprehensive look for complete business ecosystem that should cover customer, products, regulatory environment and must be part of CSP strategy. At technology front as well more evolution and standardization need to happen so its a journey that is still away from end point.
Realistically its much slower than anticipated before couple of years. If we go back to google some of projections and targets or visions published at that time and see the reality as of today then there is wide gap. And my view is that it'll not change in next 12-18 months either. We'll see success in deployments with NFV remaining lightweight, excluding pureplay LTE core (including IMS) and CPE.
Out of these CPE ( including edge routers) because it was always major operational headache and involved truck-rolls for most of faults i.e. cost and difficult to attend both. Moreover it is not an issue towards rest of network. So best target.
IMS and LTE core, because these are relatively new, lightweight and on flat IP design. So a lot of scope for innovation & collaboration.
But I am not dreaming for big bang transformation from physical to virtual for incumbents in next 1-2 years, neither I see any business compulsion when CSPs have bigger transformation to do in operations, customer engagement, system rationalization etc to be better prepared for NFV leap.
Hence its journey towards maturity from both CSP and technology evolution perspective that will converge after sometime.

You can debate the micro issues as much as you want but the macro issue is unassailable.
The old adage goes "Never bet against the Internet!".
NFV is currently in the "trough of disillusionment" phase of the technology life cycle.
Hold on, it get's much, much better!

Craig,
There does seem to be some disquiet around NFV. If you look at Tom Nolle's post he has a interesting viewpoint especially in
Would Savings from NFV or Lifecycle Automation Fund Innovation?
HIs conclusion is that the CAPEX and especially OPEX saving are not properly established outside some very narrow missions including vCPE . He also has issues with the ETIS NFV Automation approach described in other poste
Some of the suggestions he makes around intent based management are already addressed in the ZOOM HIP work in

I have been hearing about SDN/NFV trials for more than 5 years. All of the trials are very "successful" and show all kinds of improvements in time to deploy services, ability to scale up and scale down on demand, improvements in operating expenses, greater flexibility and agility you name it. So ... If the Business Case for SDN/NFV is so compelling, why is it taking so long?
I still see very few IN PRODUCTION services built from SDN/NFV systems and platforms. Does anyone have any thoughts on this?
