What is the difference between BACKPLANE and SWITCHING FABRIC?

Hi

I was looking at the specs of a 3560E and saw this:

Performance
68Gbps Backplane Speed
128Gbps Switching Fabric
101.2Mpps Forwarding Rate

What's the difference between backplane and switching fabric. Does that mean the 3560E has a built in switching fabric? If so, then frames or packets would use that instead of the backplane?

The capacity of "switched fabric"  refers to the available traffic throughput between ports on the same switching module  (ASIC).

Backplane throughput  refers to the capacity to send traffic between different modules connected to the backplane.

I believe on the 3560,  there are  8 ports connected to each ASIC,
on a  24-port switch  there would be at least 3 ASICs.

So switching frames would be faster between two ports on the same module, than
between a pair of ports on different modules.
