What is token ring and how it works?
What is token ring and how it works?
A token-ring network is a local area network (LAN) topology that sends data in one direction throughout a specified number of locations by using a token. The switch then establishes a dedicated connection between the two stations, enabling data to be transmitted and received at the same time.
Where is token ring used?
Token Ring is a computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a token that is passed around a logical ring of workstations or servers.
What is the purpose of token in ring topology?
To prevent congestion and collision, a token ring topology uses a token to ensure that only one node/station on the line is used at a time, thereby easily denoting media users of its activity. A token ring LAN is physically wired as a star topology but configured as a ring topology.
How collision is avoided in Ethernet?
Collisions can mostly be avoided by using switches instead of hubs. Switches enable for the segmentation of Ethernet networks into smaller collision domain. Whereas the use of a hub creates a large single collision domain, each port on a switch represents a separate collision domain.
How do you understand the concept of token ring?
A token ring is a data link for a local area network (LAN) in which all devices are connected in a ring or star topology and pass one or more tokens from host to host. A token is a frame of data transmitted between network points.
Why is Token Ring not used?
Probably the main reason why Token Ring failed however was pricing. IBM charged too much for royalties to vendors that wanted to produce Token Ring cards and MAUs. This made all Token Ring equipment too expensive. A Token Ring card could cost 5 and 6 times as much as an Ethernet card.
Who developed Token Ring?
IBM
One of the earliest local area networking protocols was Token Ring, originally developed by IBM in the early 1980s.
What is the topology of a token ring network?
A token ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and pass one or more logical tokens from host to host. Only a host that holds a token can send data, and tokens are released when receipt of the data is confirmed.
How are stations wired in a token ring network?
In a Token Ring network, stations (computers) are wired in a star formation to a central wiring concentrating unit called a Multistation Access Unit (MAU). This unit concentrates wiring in a star topology but internally forms a logical ring topology over which network traffic can travel.
