ATM Goals
Simplified Network Infrastructure
- Seamless LANMANWAN - Simpler Network
Management - Higher network availability - Enable
business re-engineering - Enable collaborative
computing - Data center consolidation - Payoff
is simplicity of technology - Electronic
Co-Location (Virtual workgroup)
Scalability and Flexibility
- Technology to last 10years - Future proof
nature of ATM - Faster LAN - Enable New
application - Faster Speeds - Improved
performance - Scalable Bandwidth - Bandwidth on
demand
Accommodation of Mixed Media Traffic
- Voice, video and data - Collapse various
backbones - Video Desktop conferencing - Video
seen more as an application driver than voice

  killer application,
• ATM can do all these things,

Simplified Network Infrastructure
Accommodation of mixed media traffic
ATM
Scalability Flexibility

• That's the point --- that's WHY ATM!
