3. Motivation for NGSON?
Exponentially increasing number of services and applications and their interactions
To have a better, more efficient way of providing these services and applications by means of context-aware, dynamically adaptive, and self-organizing networking capabilities.
Geneva, Switzerland, 17 October 2011

4. What is NGSON?
An IEEE sponsored effort to standardize a framework of IP-based service overlay networks
A set of context-aware, dynamically adaptive, and self-organizing networking capabilities, including advanced routing and forwarding schemes
Independent of underlying transport networks.
