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.
