Hi Pete,
Very valid point on E2E user experience. Network Services are realized across different tiers of networks that you have sighted like edge, core, transmission, IP etc. SDN/NFV is just the virtualization of these network functions across several tiers. Industry has been grappling to get E2E user experience.
Particularly, the way SDN/NFV could possibly contribute to better E2E user experience is by the virtue of having an ability to do real time correlation and analytics of network statistics and events and apply policy and rules that trigger automated workflows for preemptive and corrective measures. Having following functional blocks; this could be realized in the software :
1. Common Information Model (TMF SID; which already supports additional data entities for SDN/NFV)
2. Big Data Analytics : Have as many data sources, both static (traditional OSS, NMS data) and dynamic (software probes based real time streaming for SDN/NFV) to gather sizeable and meaningful data sets.
3. Policy Control with Rules and BPMN engine for close control loop.
Hope this helps.

With the communications industry being formed by varying Supplier/Partner levels such as ISPs, Service Providers, Core Network Providers and Access Network Providers, who each have a component of the network capabilities (Layer1, Layer 2,…), then how will SDN/NFV realistically be able to provide a role that will give a good End to End User Experience?
