What exactly is Ring Topology?

 The Ring Topology (or Ring) is configuration for networks. Each device is connected to its next device (Workstation Server, Printer,). The ring is formed to be moved through the signal.

In this manner, the data packets travel from one device to the next until they get to their final destination. Ring topology is also known as active topology because it delivers messages to every device.

The definition of Ring Topology

In a ring topology, devices are linked to a ring, and within a rings, they share information to one another or to one another according to devices that are near them. A lot of Repeaters are utilized together with Nodes to perform the task of transmitting data within Ring Topology.

What is ring topology?

In rings, topology is defined as a loop network. This means that each node in the network is connected to two connections. Because of this, it is sometimes referred to as Dual Ring Topology. This topology is utilized in computers based on networks cards in Lan or Wan.

An Coaxial Cable and an RJ-45 Network Cable are used to connect computers, depending on the network card that are used by all computers in Ring Topology.

How does ring topology get formed?

Within Ring Topology, each device is connected to two other devices. In this way, all devices connect to form a circle. This is known as a Ring Network. The data is transferred through one node and then to another via the token. This topology is known as Token Ring Topology.

If there is a huge number of nodes, the token will have to go across various types of nodes prior to reaching the destination. Because of this, data loss may occur. to stop this loss and to boost the strength of signal repeaters are regularly installed.

Unidirectional Ring - In a Unidirectional Ring Network, data flows in only one direction, clockwise or counter-clockwise. The network is referred to as Half-duplex Network.

Bidirectional Ring Bidirectional Ring Unidirectional Ring Network can be transformed into a Bidirectional Network as it has the two connection between two nodes of the network. It is also known as Dual-ring Network. In this case, two rings are created to send the information in the opposite direction.

Selecting the best topology for your network will guarantee the ease of managing network operations, as well as high performance, and improved data efficiency.

About Access Protocols

Rings are used to access circuits, packets, or a mix of both. The circuit is designed with signals that are out of band, but the packets are routed to circuits using the Medium Access Control Protocol (MAC).

Media access control controls the stations that broadcast at any given time. Media Access Protocol is divided into three classes: Slotted, token, and register insertion.

The history of Ring Topology

Ring topology was created in 1984 by IBM in 1984, and was later was defined in IEEE 802.5 standards in 1984 by the Institute of Electrical and Electronics Engineers.

Typically, this was 4mbps, but the systems that are currently in use have been upgraded to 16 mbps. Additionally, the latest systems operate at a higher speed.

The history of the ring topology, earlier times, it was utilized in schools, offices, and smaller buildings. Since networks were often small rings, but ring topology is not widely utilized today.

Benefits of Ring Topology

  • The speed at which data is transferred by this topology is very excellent.

  • The network server is not required to manage connectivity between the workstations.

  • It's a highly organised network. Each device is able to access the token.

  • You can also add more workstations and not affect the performance of your network.

  • In this particular topology data flows in one direction, thanks to which the possibility of clashing packets is lower.

  • It's very affordable to build and expand.

  • Ring Protection Reconfiguration to prevent Line faults in Bidirectional Rings is faster due to the high degree of switching.

Advantages and disadvantages of Ring Topology

  • When a workstation is closed, it affects the whole network.

  • Due to the unidirectional ring information packet (Token) must go through all nodes.

  • The Ethernet Cards and Hubs/Switches needed to connect every working station to the Internet are expensive.

  • It is extremely difficult to add or remove any node in the network that could cause issues in network's activity.

  • Moving, adding or switching devices can affect the network.

Myths of Ring Topology

Rings can prevent clashes. Rings is a term used to describe the layout of the cable. There are no clashes whatsoever that result on IBM Token Ring. This is due to Layer 2 Media Access Control.

A token rings is an example of the ring topology. 802.5 (token rings) network at Layer 1 don't use Ring Topology. In fact, the IBM Token Ring (802.5) at Layer 2 mimics a Ring.

Token passing takes place by using the rings alone. Passing tokens is only done on the rings. Passing is a way of controlling access to cables, that is implemented by Layer 2's Mac Sublayer of Layer 2.
