What is network topology?

Network topology is the description of the arrangement of nodes (e.g. networking switches and routers) and connections in a network, often represented as a graph.

No matter how identical two organizations are, no two networks are exactly alike. However, many organizations are relying on well-established network topology models. Network topologies outline how devices are connected together and how data is transmitted from one node to another.

A logical network topology is a conceptual representation of how devices operate at particular layers of abstraction. A physical topology details how devices are physically connected. Logical and physical topologies can both be represented as visual diagrams.

A network topology map is a map that allows an administrator to see the physical network layout of connected devices. Having the map of a network’s topology on hand is very useful for understanding how devices connect to each other and the best techniques for troubleshooting.

Types of network topology

There are many different types of topologies that enterprise networks have built on today and in the past. Some of the network topologies we’re going to look at include bus topology, ring topology, star topology, mesh topology, and hybrid topology.

What are the types of network topology?

Bus Topology Simple layout and cheap but vulnerable to failure and only suitable for low traffic volumes. Not used for office networks today, but can still be found within some consumer products.Ring Topology Easy to manage and with a low risk of collision but reliant on all nodes being powered up and in full working order. Rarely used today.Star Topology All devices are connected to a central switch, which makes it easy to add new nodes without rebooting all currently connected devices. This topology makes efficient use of cable and is easy to administer. On the other hand, the health of the switch is vital. This topology requires monitoring and maintenance. However, it is a commonly encountered topology.Tree Topology A hierarchical layout that links together groups of nodes. Creates parent-child dependencies between root nodes and regular nodes. This layout can be vulnerable to failure if a root node has a problem. This topology is complicated and difficult to manage and it uses a lot of cable.Mesh Topology Each node is connected to every other mode with a direct link. This topology creates a very reliable network, but requires a large amount of cable and is difficult to administer. Wifi networks make this topology more feasible.Hybrid Topology Combines two or more of the standard topologies. This can be a good solution to create quickly link together different existing networks into a unified system. Don’t confuse the term “hybrid network topology” with “hybrid system” – a term that is applied to the combination of onsite and cloud resources.

Bus Topology

Pros:

Easy installation

Fewer cables required than Mesh and star topology

Good for small businesses

Low cost

Easy to manage and expand

Cons:

Backbone performance is critical

Easily congested on busy periods

Efficiency decreases rapidly with each added node

Data can only travel in one direction at any point in time

Bus topology is a network type where every device is connected to a single cable that runs from one end of the network to the other. This type of network topology is often referred to as line topology. In a bus topology, data is transmitted in one direction only. If the bus topology has two endpoints then it is referred to as a linear bus topology.

Smaller networks with this type of topology use a coaxial or RJ45 cable to link devices together. However, the bus topology layout is outdated and you’re unlikely to encounter a company using a bus topology today.

Advantages

Bus topologies were often used in smaller networks. One of the main reasons is that they keep the layout simple. All devices are connected to a single cable so you don’t need to manage a complex topological setup.

The layout also helped make bus topologies cost-effective because they can be run with a single cable. In the event that more devices need to be added then you could simply join your cable to another cable.

Disadvantages

However, relying on one cable does mean that bus topologies have a single point of failure. If the cable fails then the entire network will go down. A cable failure would cost organizations a lot of time while they attempt to resume service. Further to this, high network traffic would decrease network performance because all the data travels through one cable.
