9. Paradigm

10. The Enterprise Challenge I want to watch the VP speech I want to watch VoD I want to upgrade my MS Office I want to run ERP Deployment of new applications Increasing data traffic Demand for rich media (video, java, etc.) services Customers complain of slow application performance!

11. Scale 100 feet100 miles
