   One of the links in the diagrammed network has lower bandwidth than the   
   link to the left of it, and the device between those links doesn't have   
   enough buffering to handle this bottleneck, so it drops packets.   
      
   E.g. A->B is 10K frames/sec, B->C is 5K frames/sec, and B can buffer   
   only 4,000 frames.
