An illustration of three ATM switches and the forwarding table in
each switch that allows a single VC to span the network. Only
those table entries that correspond to the VC are shown.

(a) Arrows showing the directions that data flows around
counter-rotating rings, and (b) the same network after a station
has failed. After the failure, stations use the
reverse path to form a closed ring.

The conceptual flow of bits during a transmission on a token ring
network. Except for the sender, computers on the network pass bits of the
frame to the next station. The destination makes a copy.
