Token Ring
• A token ring network uses a token-passing access
method. A token is small packet that move clockwise in a
circle from node to node. Only one free or unused token
is available per network; a node cannot transmit until it
has the token.
• When the node is ready to transmit, it intercepts the
token, adds data and the destination node’s address, and
then sends the token on to the next node. The token
moves from node to node around the network until it
reaches the destination node, which intercepts the token
and sends an acknowledgment back to the originating
node.
