Editor's Notes
- Why is control plane needed? Manual configuration was acceptable for yesterday’s traffic patterns: file sharing from fixed locations. Today’s traffic patterns: mobile & [mobile] video, are better suited with a CP due to the unpredictable location of the endpoints (combined with the large traffic).
- The points on this slide speak for themselves.
