Product Line Strategy
Address emerging Desktop MM Application needs...
• Desktop Multimedia Collaboration
– High Quality, Interactive
• Multimedia Information on Demand
– Simultaneous, High Quality, Real-time/Offline Audio/Video
• High Performance Data Workgroups
– Bandwidth on Demand, Virtual Workgroups, Realtime Data
... In a scaleable, transparent fashion
– Scaleable: Number of Users & Simulataneous Applications
– Transparent: Preserve existing LAN, Client/Server investment

Native ATMServices
Desktop ATM network to front-end the LAN Media Operating Software (MOS) to augment the NOS Native ATM Services such as Stored A/V, Realtime A/V, Video Conferencing
Emerging Client-Server Model
ServerFile, Message, Database Servers manage (naming, browsing, authentication, billing) specific multimedia services
MM ServicesStored A/VRealtime A/VVideo ConferencingVoice
LAN, WAN
Desktop ATM
MM ClientCan simultaneously access Data, A/V, VideoConferencing and Voice services
Why Desktop ATM?
• Provides more bandwidth, “smart” bandwidth• Allows multiple, simultaneous Classes of Service• Allows emulation of LAN, ISDN, POTs services• Is affordable, uses existing structured wiring• Enables convergence of LAN/MAN/WAN

MOS advantage
• Current NOS’s are optimised to support high throughput, burst data client/server applications
• MOS coexists with the NOS, and enables realtime multimedia applications such as stored or live Audio/Video and Video Conferencing, to directly leverage ATM’s sophisticated Classes of Service

• MOS augments the NOS to provide QoS MM• Client MOS enables Windows Client to
transparently access MM Server/Service• Server MOS frontends the MM Resource or
Service and delivers it over the ATM Network
