There are number of LAN technologies and each technology is classified into a category according to its topology , one such topology is star topology. The hub accepts data from a sender and delivers it to receiver .
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.
There are number of LAN technologies and each technology is classified into a category according to its topology , two such topologies are star and ring topology. In star topology ,The hub accepts data from a sender and delivers it to receiver, there is no security in star topology . In Ring topology Computers are connected in a circle- the first computer is cabled with the second computer.

There are number of LAN technologies and each technology is classified into a category according to its topology , two such topologies are star and bus topologies . In star topology ,The hub accepts data from a sender and delivers it to receiver, there is no security in star topology . In Bus topology all system are connected to a single , long cable.
Bus topology is also the best depending upon the situation concern
Token ring uses star topology . The data token is being passed from one computer to other allowing all the computer to have network access and avoids data collision.
A network in which there are multiple network links between computers to provide multiple paths for data to travel is called a mesh network or topology.
Layer 2 addressing not required for this topology
the ring topology is a network within which all computer are connected like in a circle. The ring topology data transmission is depending on a token. it's a programme given to a computer to allow it to communicate with others computers. it's useful but if one computer goes down, the topology is down too.
Ring topology is a setup in which the systems are connected to their adjacent systems directly....if a system wants to connect / communicate with a farther system....it sends the data through the different systems on the path, so, there is very less security of data and encryption algorithms are the only way to protect the data
A network topology in which network nodes are connected in a circular configuration. Each nodes Examines the data sent through the ring and passes on data not addresses to it.this iz ring topology A network layout or design in which each node is connected to a central hub. The hub establishes, maintains and terminates all connections between the nodes. In a LAN, the hub is likely to be a workstation, whereas in larger multi-point networks the hub is more likely to a multiplexer.this is star topology jyoti bhubanesw3ar
The logical topology for a bus topology is the same it is a bus topology
With all network topologies there is the ability to send data either way, e.g. uploading and downloading.
Ring topology is the passive topology in computer networks
VSAT is the acronym for Very Small Aperture Terminals. VSAT are mostly configured in one of the following network topologies: a star topology, which uses a central uplink site such as an NOC (network operations centre) to transport the data back and forth to each VSAT terminal. This transportation of data to each VSAT takes place through satellite communication. The mesh topology is a type of network topology in which each of the VSAT terminals relays the data via satellite to another terminal. The VSAT terminals act as an information hub. The main advantage of this type of network topology is that it minimizes the need for a centralised uplink site. At times the star network topology and the mesh network topology are combined, which combines the main activity of both network topologies, namely acting as both a central uplinking site and an information hub, which transfers data back and forth to each of its interconnected terminals via satellite communication.
