JTC 1/SC 6’s Considerations on FN
Future Network is the Network of the Future It does not mean only the networking aspects
It includes all aspects of Networking as well as Services
ITU-T’s Term: Future Networks
ITU-T SG13 expects various FNs in the future
It also includes Evolutionary Approach
No specific network technologies are pre-assumed Clean-slate design Approach
It means that a system and network are designed from scratch. It should be based on long-term, revolutionary approach. In clean-slate design approach, the backward compatibility may not be required.
This work is distinct from NGN and will not compromise nor endanger currently operated networks

Smart Ubiquitous Networks (SUN)
What is SUN ?
Bridge between NGN and FNs
IP-based packet networks that can provide transport and delivery a wide range of existing and emerging services to people and things.
The services provided by the networks can cover aspects such as control, processing and storage.
The networks are smart in the sense that they are knowledgeable, context-aware, adaptable, autonomous, programmable and can effect services effectively and securely.
The networks are ubiquitous in the sense that they allow access anytime anywhere through varied access technologies, access devices including end user devices, and human-machine interfaces.
