I believe that non blocking states that a switch fabric can support all
ports at maximum speed and throughput without running out of capacity, where
as a blocking fabric cannot. There is a good book that explains cross bar
and shared bus architectures in routers, I assume that the same would follow
for switches. The title is Inside Cisco IOS Software Architecture from
Cisco Press, it is also very good at the explanation of the difference
between switching methods within routers, some of the stuff that it is not
easy to find information on.

Hi Group,
Anybody got a good explanation (or links) about the differences and
advantages between crossbar, shared bus (central/distributed) and shared
memory swithing architectures ??? Also those terms as blocking and
non-blocking, there significance on switching performance.
Appreciate any response.
Thanks and regards,
Neil
