some users have complained about performance. Fuster Bunn is very satisfied with the Net
Greeting program, but it is concerned that the rest of the network's performance seems to be
suffering as a result. After performing network analysis, Peter determined that when 10 Net

network. ATM is recommended as the key core infrastructure technology because of ATM's
guarantee of true multiservice capability with high-bandwidth efficiency and service quality
across all services. ATM also addresses the broadband traffic demand within the Distributed
Learning WAN backbone and provides the transport service for locations requiring only
narrowband resources. Of equal significance are ATM's access and gateway devices, which can
handle the classes of service needed for video with fairness and high quality.
