  • 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.
