Xiaobian to share with you what is the ring topology in the computer, I hope you have something to gain after reading this article, let's discuss it together!

If the nodes of the network are connected into a closed loop by repeaters, this topology is called a ring topology. A ring topology is one in which nodes are connected to a closed loop by repeaters, and data travels in one direction.

If the nodes of the network are connected into a closed loop by repeaters, this topology is called a ring topology.

A ring topology is a closed ring formed using common cables. Each node is directly connected to the ring, and information is transmitted from one node to another along the ring in a certain direction. Ring interfaces generally consist of transmitters, receivers, controllers, line controllers, and line receivers. In a ring topology, there is a "token" that controls the right to send data. It is transmitted in a certain direction around the back. Every time it passes through a node, it must be received. It is judged once. If it is sent to the node, it will receive it. Otherwise, it will send the data back to the ring and continue to transmit it.

Each node in the ring structure is connected in a closed ring communication line connected end to end through the ring interface. Each node in the ring has the same status. Any node on the ring can request to send information. Once the request is approved, it can send information to the ring. The data in the ring network is mainly unidirectional and can also be transmitted bidirectionally (bidirectional ring) according to the design. Because the loop is common, the message sent by a node must pass through all the loop interfaces in the ring. When the destination address of the message stream matches the address of a node on the ring, the message is received by the loop interface of that node and continues to flow to the next loop interface until it flows back to the loop interface that sent the message.

The characteristics of ring topology are as follows:

(1) The cable length is short, and only the nodes need to be connected one by one.

(2) Optical fiber can be used. The transmission rate of optical fiber is very high, which is very suitable for unilateral transmission of ring topology.

(3) All sites have fair access to other parts of the network, and the network performance is stable.
