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 contextaware, dynamically adaptive, and
self-organizing networking
capabilities.

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.

Information Flow Example:
Service Composition (Static)
Composite Service 1 … n
Service Requester
SR FE
Service 1 … n
SC FE
1. Service request
2. Route to composite service
4. Invoke base service
3. Service execution,
invoke service
5. Route to base service
6. Service response
7. Route response to SC FE
9. Service response
8. Service execution, reply
response
10. Route response to request
