A protocol is a set of rules for describing how to successfully exchange information between two systems.
1.) Mesh topology:- Routing protocol such as RIP(routing information protocol) or OSPF (open shortest path protocol) is used. 2.) Star topology:- Ethernet, token ring, Local Talk, ATM........... all are used... 3.)Bus topology:- Ethernet protocol using CS-MA/CD as access method.....

You are thinking ring topology. Not used much today.
A spanning tree protocol, or STP, is characteristic to a LAN. It provides a loop-free topology for networks within the system.
The media access control protocol can be very simple
For WANs depending on the protocol the packets can be very different. For LANs, the ring topology insists on special packets proceeded by a "token".
Enhanced Interior Gateway Protocol It is a Cisco proprietary protocol. It uses bandwidth and delay by default to calculate the best path. It can also use load and delay, but these are usually not used. It is a distance vector routing protocol. It keeps a topology map, but it is only similar to the topology map of link state routing protocols.
protocol, token, proxy or packet
Also called signal topology. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data -- the physical structure of the network -- is called the physical topology. The logical topology, in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. Logical topologies are bound to the network protocols that direct how the data moves across a network. The Ethernet protocol is a common logical bus topology protocol. LocalTalk is a common logical bus or star topology protocol. IBM's Token Ring is a common logical ring topology protocol. A network's logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology.
A ring topology graph will normally indicate the details of a network's structure. In a ring topology graph, information on individual machines will be shown and indicated. This information will include a Media Access Control address, as well as the Internet Protocol address for a network communicating device. Ring topology graphs are meant for understanding the layout of any given network design.
