  "The impact of memory architecture is a much researched, but little
   publicized element to the performance of today's network switches.
   Many academic papers have been written about the advantages of output
   queued shared memory vs. combined input-output queued (CIOQ) memory
   architectures over the years."



Traditional CIOQ Architectures
Output Queued Fabric Architecture
Multicast Capability
Memory Size Comparison
Measured Results
  "To show the performance advantage of this memory article it's
   important to look at the performance of both architectures.  We'll
   do that now through an examination of the FocalPoint FM4000, one of
   the first switches on the market to feature an output queued shared
   memory switch."

最後の一文は予想通り
  "Test results using a FocalPoint FM4000 series switch show that an
   output queued shared memory architecture can provide low latency,
   fairness and excellent multicast performance in the face of
   disruptive background traffic."
