Next generation networks - multi-service network design

The work presents a collection of slides about network transformation that requires the evolution of multiple network layers in the same timeframe. Network usage is application driven, and there is a great deal of uncertainty in applications demand and user behavior. Operators face critical choices in network architecture and technology that can have great impact on their business goals. A unified multi-service, multi-layer and multi-vendor approach is needed to common application traffic modeling, flow through of results, sophisticated optimization algorithms, automation for what-if studies, models that link technical and financial analysis. The problems are too complex for traditional planning methods.
