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

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
