Transparent bridges are devices which connects more than one network segments
with other
bridges to make all
routing decisions. A transparent bridge is essentially used to learn the
MAC addresses of all
nodes
and their associated
port, to
filter incoming frames whose destination MAC addresses are located on the
same incoming port, and to forward incoming frames to the destination MAC
through their associated port@.
There are two types of Transparent Bridge Modes:
- Store-and-Forward: Stores the entire frame and verifies
the CRC before forwarding the frame. If a CRC error
is detected, the frame is discarded.
- Cut-Through: Forwards the frame just after it reads the
destination MAC address without performing a CRC check.
