Accommodation of Mixed Media TrafficAccommodation of Mixed Media Traffic
- Seamless LAN=MAN=WAN - 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)
- Technology to last 10+years - Future proof nature of ATM- Faster LAN - Enable New application- Faster Speeds - Improved performance- Scalable Bandwidth - Bandwidth on demand
- Voice, video and data- Collapse various backbones- Video Desktop conferencing- Video seen more as an application driver than voice
Conclusion: Why ATM!Conclusion: Why ATM!ATM deployment is not dependent on any ATM deployment is not dependent on any single “killer application”,single “killer application”,ATM can do all these things,ATM can do all these things,
That's the point --- that's “WHY ATM!”
