Ring topology
A typical ring topology is illustrated in Fig. 6.3.4.-1.
It is very similar to the bus topology except that the loop is closed from the
switch N back to switch 1. This provides some level of redundancy, if any of
the ring connections should fail.
This topology is more cost effective of the star topology, but less than the bus
one. In addition, it offers a redundancy in the loop, but in this case it requires
the use of switch able to change to linear topology in case of a fault.
