10. System Flexible Networking
Completely IP Based ：“Why IP Technology?
IP Technology is basis for converging networks
IP Technology potentially allows for an easy and full-fledged integration in the existing IP infrastructure of the customer
IP Technology holds potential cost advantages for network operators and promotes the use of standard HW (COTS)
One IP/MPLS backbone network for several communication & data services
Evolution from customer-specific or proprietary HW in IT environments
IP Technology has become mature in offering high quality media services by MPLS, QoS Tagging and Traffic Shaping
