Hello,   
   I'm curious as to what a Content Delivery Network is. For example, if someone   
   in China is watching a French TV station, my intuitive idea as to CDNs is that   
   there is some company's *private fiber* between France and China, or maybe   
   somplace else in Asia.    
   And then of course, they have what Youtube calls an "Edge" server, that is, it   
   degrades the video in real time according to the bandwidth, but that's another   
   story.   
      
   But doesn't this Fiber cost a LOT of money? How is the whole thing financially   
   viable?   
      
   Can anyone explain - give me the *entire* picture of how a CDN works?   
      
      
   Thanks :)
