CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Switch Theory of Operation
Three Switching Modes
Feature Function Benefit
Cut-Through
Switches with
minimum and
constant latency,
approximately 35 µs Lowest possible switch-latency,
which means optimal response
time for end-users.
Store and Forward Each packet is
forwarded only after
the entire packet has
been received by the
switch. This is used
for data transfer
between LAN
segments of different
speeds or for LAN
segments with a high
error rate. Does not propagate errors to
other segments.
Auto
(Adaptive
Cut-Through) Cut-through
switching that checks
for error packets. If a
port’s errors exceed a
user-defined threshold
then the port switches
to store and forward. Same speed as cut-through
switching, but with built-in
adaptation to errors which
means that bandwidth is
effectively preserved
