Ring Network In Information Technology – When it comes to network design, it is important to understand the advantages and limitations of different topologies, especially the use of ring and star topologies.
In a ring Each button connects to adjacent buttons on either side, creating a ring or loop. Although there are two paths to each button. The disadvantage of requiring a protocol such as Spanning Tree Protocol (STP) or Ethernet Protection Switching Rings (EPSR) is the advantage of adding redundancy to prevent transmission storms from occurring.

In addition, When a change or failure occurs in the network; Switches must remove their internal tables and learn about the network topology, which can disrupt services such as video and IP telephony. This outage is particularly noticeable in STP because the protocol takes some time to recover. Ringing protocols such as EPSR are specifically designed for fast recovery to limit disruption to real-time services such as voice and video.
What Is Ring Topology? Definition
Within the star topology, A core switch connects to every other switch to form a star. to deliver redundancy within a star topology; Then you need two links to each switch that are combined using link aggregation. Since the core switch represents a single point of failure; It is important to add a second switch, and ideally it uses a chassis stacking technology such as Virtual Chassis Stacking (VCS) so that both switches can be managed as one logical switch.
Star topologies require more interfaces than ring topologies without disrupting service in the event of a fault. Cost implications can depend on many factors, including the type and speed of fiber used.
It is not a simple matter of which topology is better, but it is important to understand to ensure that the solution meets the needs of the customer and their applications. In general, A star topology provides a more resilient network than a ring topology, but requires more interfaces. Because each switch has dedicated bandwidth; Bandwidth requirements for links in a star topology will be lower than for a ring. This means that a star topology can actually result in lower cost solutions than a ring topology when there are more interfaces.
It is also important to understand that a star topology can be delivered over the cable infrastructure used as a ring to accommodate the band diversity of a ring and the tolerance of a star topology. This is illustrated in the figure below.

When using a ring topology; It is important to use an advanced protection protocol such as EPSR to ensure that services are minimally interrupted in the event of a link or device failure.

Solution Guide: Distributed Network Cores Build distributed network cores with Allied Telesis switches; Ideal for large campuses and data mirroring environments. We consider topologies, star topology; An introduction to bus topology and mesh or fully connected topology has already been discussed. This is the last in a series of blog posts on network topologies. In this blog post, We have a ring topology; We will discuss its advantages and disadvantages and typical uses of its architecture.
In ring topology, All the nodes are connected to form a closed loop as shown in the figure below:
Welcome! Thank You For Joining Us. We’ll Get Started In A Few Minutes.
However, Data can travel within a ring network in only one direction using a token. A token contains certain information and the data along with this information is sent across the network.
For example, Suppose A wants to send data to C; Let’s assume that the token rotates the circle counter-clockwise. Then the first E receives the token and the addresses don’t match, so E moves on. Then D receives it and goes through it that way because the addresses don’t match. C then receives it and since the addresses match, C takes the token and retrieves the information stored in it.
Similarly, If a device wants to send data; It has to wait until it receives the token. The data is then transferred to the destination and sent in a similar process as shown in the above figure.
Since there is only one token and no two stations can transmit at the same time, Collisions are very rare (unless there is a bug in the system). Compared to bus topology, ring topology is an efficient approach.

As with star topology, No other station is preferred. All machines share the same resources. Therefore, in terms of performance, The system is fair.
There is no need for hardware such as switches or hubs as in star topology. The distance between any two nodes is also limited or can be limited as opposed to the bus topology. Therefore, ring topology is a very economical approach compared to other topologies.
This is evident from the tokenization mechanism described above. If a link breaks, tokens can no longer be sent and the entire system can be shut down.
Even if one computer goes down, the entire network can go down because the token goes from computer to computer.

Compared to star topology. Ring topologies are slow because the token must pass through all computers before reaching the destination. Some computers that need to send data to others may have to wait a long time until they receive a token. Therefore, the efficiency of this mechanism is low compared to other techniques.
Ring topologies can be used in computer labs to interconnect a few computers. But the use of ring technology has decreased over time.
In the last blog posts we talked about the star policy and the bus policy. This is the third in a series of blog posts on network topologies. In this blog post, mesh/fully connected topology; I will explain its pros and cons and typical usage of its architecture. Mesh or Fully Connected Topology – In a mesh or fully connected topology; All nodes are interconnected with each other without using a common interface. In this blog post: Advantages of Mesh / Disadvantages of Fully Connected Topology / Uses of Mesh / Fully Connected Topology For example, As we discussed, In a star topology, All network devices are interconnected using a switch or hub; In bus topology, All devices are interconnected using a bus line. More topics to discover: Bus Topology Ring Topology Star Topology But as the name suggests, in a mesh or fully connected topology. All devices are reciprocal
In a previous blog post, We discussed a brief introduction to network topologies and focused on “>star topology. In this blog post, we will discuss the features, advantages and disadvantages and usages of bus topology. In this blog post – Advantages of using bus topologies Disadvantages of using bus topologies Usage Bus topology – In a bus topology, all devices are connected to a central cable (called a bus). Through interface connections (BNC connections) as shown below: More topics to search: Star Topology Mesh or fully connected topology Ring topology Bus topology terminators are added as shown at the end of the red boxes in the figure above to prevent signal reflection. In bus topology, only one device can communicate at a time. To avoid packet collision, All other devices should wait until the bus line is free so they can communicate using a protocol called Distributed Access Protocol (DAP).

Network topologies deal with how network devices are connected. Suppose you have a switch and 4 computers; There are many ways to connect it. The figure below illustrates some ways to connect them: Thus, Network topologies are about the study and connection of such computers in different ways. When connecting in different directions; It is necessary to pay special attention to the advantages and disadvantages of each method rather than randomly using some topology. Therefore, This blog post covers different topologies; We will discuss their pros and cons and where each of these topologies is commonly used. Star Topology – As shown below, a star topology is a topology where all computers are connected to a centralized hub or switch. Therefore, Each of these devices is given the same opportunity (directly) to contact the switch, and all devices extend from a centralized hub or switch. In this
