Difference between Network Topology and Network Architecture

This is a question that we get time after time in comments and direct messages – it looks like that these 2 terms sometimes are confused, and in today’s post we decided to write our own opinion on this topic.

 

In our understanding difference between Network Topology and Network Architecture is mainly as follows:

 

  • By Architecture, we understand Layer Structures of network – Usually it will be or Three-Tier architecture including Core, Access and Distribution Layers

 

Example of Three Tier Network Architecture then will look something like this:

  • By Topology, we understand how network elements are connected with each other, within one Layer, or between Layers as well.

 

As an example of different network Topologies, we can mention Mesh, Star and Hybrid Topologies.

We suggest learn more about Network Architectures in this article, and about Network Topologies in this article.

 

 

Testimonials

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
