I guess no one has said much on this subject because, I suspect, as you ask the question the challenges that we were facing has evolved into something new and potentially more complex than we originally thought.
The ground keeps on shifting and as we come close to identifying what we are facing all variables or key variables changes and presents themselves in different formats to be taken into account as the solution is going through tests/verification stage. All this leaves very little room for solutions to be designed that would comprehensively address what we just discovered as a huge challenge.
Put simply, the playing field is not set and cannot but for a splitting second be set, because we are reacting to the possibilities that exists in the content driven bandwidth hungry demand for communication services. This is a good thing as it forces innovation and shape our thinking of what we anticipate will happen in the very near future.
Whilst there may exist the capacity to handle all the traffic, deliverying this capability and guaranteeing the applications QoS requirement is near impossible but achievable in small steps.
I should know, I spent a good long time designing an All-IP Service Provisioning and Activation OSS system for a huge European national provider/carrier. The solution is operational and has been extended and incorporated as a component of enterprise-wide OSS platform.
