Although there is no standard definition for the network complexity yet, there are many subjective definitions.

In today network designs decisions are taken based on an estimation of network complexity rather than absolute, solid answer.

If you are designing a network, probably you heard many times a KISS (Keep it simple and stupid) principle.

We said that during a network design you should follow this principle. As you will see in the later in the article ,if you want to have robust network you need some amount of  complexity.

Today I throw a new idea which we should use as a principle for the network design.

“SUCK” it is the abbreviation of “SO UNNECESSARY COMPLEXITY IS KEY”.

People refuse to have network complexity and believe that network complexity is bad. But this is wrong !

Every network needs complexity, network complexity is good !

Let me explain: Read more
