Ring Network Topology

Ring Network Topology Diagram


A network topology in which each of the nodes connects to two other nodes, resulting in forming a continuous pathway for the signals through each of the nodes known to be called the “rings”, is known to be called as a “ring network”. Data within such networks is known to be traveling from one node to another node, through all the nodes one by one along its way handling every single packet. The mentioned “rings” can be “unidirectional”, having all its traffic travelling clockwise or anticlockwise all the way around the ring. Also, it can be the so called “bidirectional”, providing only one single pathway between two nodes out of many other nodes. A unidirectional ring network is known to be very likely disrupted by the failure of some link appearing to be nearby.

A node failure as well as any cable break may lead to isolation of every single node, which is attached to the “ring”. Some of the ring networks are known to be adding a so called "counter-rotating ring", also known to be called a “C-Ring”. Adding the mentioned ring can be done for forming a redundant topology. Thus, once break happens, a data may get wrapped back on the ring before it reaches the end of the cable. Such data is known to be maintaining a path to every single node all the way along the resulting counter-rotating ring.

The "dual ring" networks are known to be including the so called “Spatial Reuse Protocol”, as well as the “Fiber Distributed Data Interface”, or “FDDI”, and the “Resilient Packet Ring”. The well-known “IBM token ring networks” are also sometimes called as the “802.5 networks”. They are commonly used for avoiding all the possible and existing weakness of a ring topology by using another topology — a “star” one. Such mentioned topology is usually used at the physical layer for imitating a ring at the so called “data link layer”.

Some of the previously mentioned “SONET/SDH rings” have two sets of the bidirectional links, which can be found between the nodes, allowing the failures or maintenance at the multiple points of the same ring resulting in no loss of the primary traffic on the outer ring in a way of switching the traffic on the inner ring after the so called “failure points”.

One of the advantages of using such network topology can be mentioned the convenience of using it for performing in a better way than a bus topology does, especially in the cases of the need of loading under the so called “heavy network”. The mentioned network topology is known to be used within a very orderly network having every device accessing to the “token” having the opportunity to transmit. Such ring network topologies do not require any central nodes for managing the connectivity between different computers. Because of such point to point line configuration of devices with a device on another side, it is quite simple to install as well as to re-configure whatever is needed by removing or adding any device.

Another special feature of the ring network topologies is its “point to point” line configuration, which makes it much simpler to isolate all the previously identified faults. Also, the reconfiguration for line faults of bidirectional rings in ring network topology can be very fast, having all the switching happening at the highest level, leading to the traffic not requiring any individual re-routing.

The disadvantages of the ring network topology: first of all, it is always more difficult to configure using it to compare to using a “star” one as any node adjunction equals to the ring reconfiguration and shutdown. One of the malfunctioning workstations within the ring network topology can create lots of problems for all the network. This can be solved by using a switch or a dual ring used for closing off the break. Every time there’s some moving, changing and adding the devices can affect the entire ring network and the communication delay is known to be directly proportional to the number of all the existing nodes in the ring network.

It is important to remember that any ring network may afford the so called “fault tolerance” to the telecommunication network having two paths between any two nodes on the network. Ring protection is known to be a system commonly used for assuring any needed communications, continuing in the event of failure of only one path. The most widely used protection architectures are “1+1” as well as “1:1”.

In 1+1 architecture, every single protection path is known to be used for protecting the signal having the bridge at the head of the path on a permanent basis, while the switching occurs at its tail end. There are more than two parallel routes are sent in this architecture traffic and the receiving end is known to be selecting the better of the mentioned two signals. Once some failure occurs, the destination switches into one of the alternative paths. The mentioned architecture is quite a widely used for as it is simple for implementing, resulting quite fast restoration. Although, there’s still a drawback, which is the wastage of the bandwidth, occurring for a reason of no traffic traveling through the redundant path.

    Network Topologies

    When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.Common Network Topologies Diagram

    Fully Connected Network Topology Diagram

    There are several basic topologies including bus, star, point-to-point, ring and a hybrid. Two computers can form a fully connected network topology, and as the number of network nodes increases, the network diagram gets more complicated. This type of topology is also called a full mesh. This is a visual example of a computer network built using a mesh topology. This diagram presents the schematic structure of the full mesh network topology. A common mesh network topology means that each network device is connected with several points in the network, so if the one node of the network goes down, it does not cause an issue with an operability of the entire computer network. In a full mesh network topology, every computer or device in the network is interconnected with each of the other devices in the network.Network Topology - Fully Connected
