Now: separate networks for separate services Low transmission delay Consistent availability & performance Reliable quality of service Class-of-service Consistent availability & performance SLA support Security Variable transmission delay Inconsistent availability & performance Best-effort quality of service for all traffic 00-03-03 / #5
Next-generation: one network for all services Consistent availability & performance Class-of-service differentiation Reliable quality of service for each defined traffic type: - voice - video - Internet access - private data - etc... 00-03-03 / #6

The intelligent network services model Closed environment Proprietary service-development tools Complex signalling & interworking Long service-development cycles (around 2 years) 00-03-03 / #8
The next-generation services model Open environment (under 1 year) Commercial service-development tools Standard interfaces Short service-development cycles 00-03-03 / #9
Three emerging classes of next-generation service Access services Single-pipe access to the service provider network for voice, data and multimedia traffic Can also include user control & configuration and bandwidth-on-demand Interconnectivity services Virtual network equipment, providing customer-specific switching functionality: IP VPNs IP centrex Application services Address the particular need of a vertical or horizontal market. Examples include: web-enabled call centres unified call & message management multimedia conferencing 00-03-03 / #10
