- Public transport services support QoS
- Home/enterprise network support QoS
- Access control
- Usage reporting facility
- Location reporting facility
- Mostly standardized
- Free for all in the home enterprise

- There is a message from Jane in Engineering about
the project they are working on - John places a phone (audio) call to Jane
expecting it will be a short call - The situation is more complicated and they add a
video link to the call so they can communicate
better - Jane feels the need to draw something for John
and to conference in Fred and Alice

This is NOW
- Multi-service Terminal
- ONE network connection
- Terminal integrates view on multiple accounts
- Service provider creates new services
- Terminal is service agnostic
- Terminal can be built TODAY
- Public network is not up to it
- Customer premises network usually neither but has
bandwidth in abundance

Conclusion
- Flashy services are built out of dull
components - TISPAN should create benchmark flashy service
descriptions - No need to implement all of them!
- Will show us which base components are needed
- Describe service aspects end-to-end
- Enable service construction
- Cheaply build new services from base deployment
- Standards required for use and interconnection of
all supported services. - Vertical Transport Connectivity
- Horizontal Transport, Connectivity, Application
- Service capabilities provide the right
granularity - NoteNot all capabilities may need to be provided
to all parties at the same price - Do not stifle innovation, do not standardize too
much!
