What is Hybrid Topology in computer networks?

The network topology is a logical and physical arrangement of the connected computers or devices.  There are five basic types of network topologies we have described.

Hybrid Network Topology

As the name suggests, the hybrid topology is the combination of one or more basic network topologies.  While planning for a hybrid topology, we need to select a topology for the backbone to connect sub-networks.  Each sub-network has its network topologies, and those could be the same or different.

The mainly used backbone topology is the bus topology.  In this tutorial, we will discuss the details of the hybrid network topology.  Possibly will cover the network sub-network of each type.

What is a hybrid topology example in real life?

The hybrid topology comes into the picture where various independent segments connect to each other.  For example, you may have various departments in an office on each floor when there will need to connect all departments. A backbone will be created, and then each sub-network will have a link to the backbone.  This section will cover various examples of hybrid topology.

Bus and star hybrid topology example:

Bus and star hybrid topology example

With the help of the diagram, we can explain the hybrid topology with star and bus types.  The two-star topology subnetworks connect to each other over a bus network.  Each star network has a switch that connects to the computers in the subnetwork.  Each subnetwork connects to the other sub-network with the link between bus and switch or hub.

Advantages of hybrid topology:

There are many advantages of the hybrid network topology tope. Here we are listing them.

  • Hybridge topology gives the flexibility to join various types of independent networks.
  • It is cost-effective, as each network can be developed based in a cost-effective manner. E.g., If a subnetwork just needs a few machines, then we can use a bus topology rater, spending more money on purchasing a costly router or switch.
  • Easy to scale computer networks using existing various types of subnetworks.
  • It can take advantage of each type of network topology feature.

Disadvantages of hybrid topology:

Like any other thing, the hybrid topology also comes with some disadvantages.  Following is the list.

  • Single point of failure. If the backbone fails, all communication stops.
  • There are various types of devices are involved, so sometimes, it is expensive to create an intentional hybrid topology network.
  • More complexity.  A mix of types of items and networks creates complications in the network.
