In a ring topology, the nodes on both sides of the break will loop the path (self-healing) back towards the ring, so every node is still communicating with each other.
star topology,bus topology,ring topology,mesh topology etc...
Ring topology
Ring and star are two.
Ring Topology is least affected by addition or removal of nodes

How does Token Bus (IEEE 802.4) enforce discipline on a logical ring topology? ----
An old topology called Token Ring
Token Ring is an active topology - each packet must be recreated as it goes from client to client.
Star topology:- In this topology all PC are connected with the central device. Central may be HUB and SWITCH. Star widely use in all over word. Ring topology:- In this ring topology all PC are connected in the frame of ring are close Ring topology use MSAU each PC has a two never road one is called up Stream and called down stream. It used token passing Matterhorn which implement the token ring network. " Is the best of star topology".
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
protocol, token, proxy or packet
You are thinking ring topology. Not used much today.
